In Praise of Holy 40 Martyrs of Sebaste – a medieval work by Saint Clement of Ohrid (The Wonderworker)

Wednesday, March 9th, 2022


I consider / think for the will of the same mind and the equality of wisdom of these fourty martyrs and in amazement, I resort to Christ,  by whom clearly comes every good giving and every gift, as the Many-Blessed Paul said and blessed: “Thou are Christ – a God’s power and wisdom.” And with that power, were filled the many-blessed fourty warriors, martyrs for Christ.

They shone in the world like the brightest stars and illuminated the whole universe with the rays of the knowledge of God, having among them the spiritual sun – Christ. Illuminated by its light and adorned with great beauty, they blossomed with special faith like fragrant lilies, abundantly watered with the dew of the Holy Spirit. Decorating themselves with good deeds, they became beloved of their Lord, because in purity and love they surpassed each other. They shone like lamps with spiritual radiance: some with fasting and abstinence, others with good faith and hospitality; some with kneeling prayer and sincerity, and others with humility and meekness; some with vigilance and sincere love, and others with love and mercy for the poor. Indeed, the power of the Holy Spirit was with them, urging them to every good deed and by faith protecting them from every calamity.

And so, they were as homogeneous in appearance and beauty. Weaved through faith and love like a golden necklace, they were connected to each other by unanimity. Leaving the vain way of life, they zealously wished to stand before the unspoken glory of God through good deeds and sincere love. They urged each other to hurry to the holy path of feat. Instead of armor, they put on the faith, and instead of a shield, they armed themselves with The Cross and appeared in battle like Lightning – Riding against thousands and tens of thousands and were glorified with Victory. They fought a double war – with Visible and Invisible enemies.

The devil, who could not see their beauty and faith, as well as their pure life, fought against them by entering the malevolent court of Licinius, who was autocratic at the time. He raised persecution against Christians. Wanting to deceitfully capture the faithful martyrs, Licinius forced everyone to worship idols. But the ancient prophet proclaimed and said: “Lord will not leave the rod of the wicked on the lot of the righteous, so that the righteous do not stretch out their hands to iniquity. Lord, do good to the good and to the righteous at heart! ” With this light they illuminated themselves, striving brilliantly and wonderfully in martyrdom, despising the ordinary pleasure of joy. Cheering each other on, they said to each other, “Brethren, let us not be afraid of this short-lived torment, which passes quickly like a shadow, but brings us into the eternal dwellings. Therefore, brothers, stand firmly armed against the adversery-enemy, so that we may be adorned with victorious crowns of Christ God!
Because for the sake of earthly life and for the sake of the mortal king we did not spare ourselves in battles, but, having fallen into many troubles, protected by the power of God, we emerged victorious, then – if we try to follow him, taking upon ourselves his voluntary sufferings, we hope that he will be with us, as he promised: “When you are taken to assemblies, to authorities, to prisons, to kings and princes, and to tormentors for my name's sake, do not worry about what to say or what to answer, for I will give you words and wisdom that all your adversaries will not be able to resist or contradict. And do not be afraid of those who kill the body and can do no harm to the soul; but be afraid of him; who, after the murder, has the power to throw into hell. "

With these words, they learned and supported each other, and powerfully trampled on the devil's cunning. They gladly endured all kinds of sorrows, saying to themselves the apostolic word: "God is not unjust, brethren, to forget your labor."


40 Holy Martyrs of Sebaste martyrdon in the Lake Εκκλησιαστικό Μουσείο (Alexandrupoli, Greece Church Museum)

When they stood at night, in the cold, in the middle of the swamp, near the town of Sebastia, here is one of them, turning away, ran to the bathroom (built near the plateau) and, touching the heat, it melted like ice and died. And suddenly an unspeakable light shone from the sky on them, and the cold turned from it into warmth. And forty crowns descended from heaven upon their heads. Only one wreath remained, with nowhere to stop.The guardian, seeing this miracle, took off his clothes, jumped to the martyrs and cried out in a loud voice: “I believe in the Son of God Jesus Christ, in whom even these holy martyrs believe; may He honor me with the same glory, so that I may complete with them a martyr's deed! ” And immediately the crown of unspeakable glory descended on his head and stood. This is God's mercy, as the Lord Himself said, "The last shall be first, and the first last."

Therefore, how can we praise the most holy company, from which this wretched man fell away, as Judas once fell away from God's chosen company, and as the devil fell away from the angelic staff and from the light and became the ruler of darkness and deserved eternal torment. His envy engulfed this wretched man. But still the devil was trampled by the invincibles.

The church nourished them with spiritual food, crowned them with the brightest wreaths; he made them companions of the angels and showed them to the whole universe as bright lamps. With their miracles they shine more than the sun. The prophet announced about them in antiquity, saying: “You have tested us, O God, you have melted us as silver is melted; put men over our heads. We went through fire and water and you set us free. " As they desired this eternal peace, they left behind the beauty of life, houses, wealth, fathers, mothers, sisters and brothers, wife, children, and even despised their lives, according to the Lord's command. That is why the Lord has miraculously shown all His favor to them. Indeed, they were vessels of good use, chosen for the service of the only ruler and our savior, Jesus Christ. Nothing could separate Christ's love from them: no fire, no water, no other suffering.

That is why today we celebrate their memory with respect and, giving them the due praise, we say: "Rejoice, all-honorable and wonderful company of the most glorious army!"

They became like the disembodied forces and surpassed them; for they, being disembodied, stand in their place and enjoy the unspeakable beauty. And the martyrs, having swum the earthly ravaged sea , illuminated the whole world with their blood. With spiritual wings, they flew up and stood before the unspeakable glory of God. They abundantly heal the sick, cast out demons, alleviate suffering, enlighten churches, keep the peace, guide people to good deeds, cast out demons and quickly destroy their cunning, enrich the poor in two ways – mentally and physically – destroy heresies. Shining with the brightest dawns, they became great advocates – martyrs for the faith.

So what mouth or which tongue will be able to praise these heavenly lamps, which appeared brighter than the sun? With their pure relics, they illuminated the whole world like stars. They warmed the day's frost, ignited by the Holy Spirit. And fiery flames extinguished them, as once the godly youths in Babylon. With their golden bones they illuminated the streams of the river, adorned all the churches with their fragrant relics, delighted the world with their unspeakable miracles, banished deception, and planted the truth, stepped on the devil, rejoiced Christ! That is why the right hand of the Almighty adorned them with bright wreaths and illuminated them with the rays of the unspeakable light, honored them wonderfully and with the honor to stand before God, clothed them with God-woven clothes, filled them with the power of the Holy Spirit and made them equal to disembodied forces. . That is why God is wonderful among his saints, always glorifying those who glorify him, and miraculously honoring them with unspeakable miracles. I want to tell one of their many miracles, namely how children listen to their noble mother.

When these blessed martyrs surrendered their holy souls into the hands of the Lord, one of them was still breathing. His mother, seeing that he was left alive, rejected the female weakness, took male audacity, took his beloved son on his shoulders and, following him (after the car loaded with the bodies of the martyrs), said to him: "Do your best, Sufferer for Christ, be courageous and strengthen your heart, and may my soul rejoice for you! Do not fall away, as Judas once fell away from the apostles, nor as one of you has now fallen away, but give God all your hope and your spirit, and he will support you; for, behold, Christ is standing before you, brother, to receive your soul and await your arrival. ” As she spoke this, her son, carried by her, surrendered his soul into the hands of the Lord. She took it, placed it with the saints, and said, "Rest, child, with your holy company, and remember me with them in your holy prayers, so that I may accomplish your martyrdom." Then she returned with joy, praising God. Have you heard, brethren, of the love and boldness of the Christ-loving mother? How she feared neither the king, nor the tormentor, nor the sword, nor the fire, but only the life-giver of God.

Therefore, if we reject from ourselves any fear of men, let us make room in ourselves for the fear of God. May he enlighten our souls and hearts! May we always abide in fasting, in purity and sincere love, in meekness and obedience, abstaining from all evil. Let us adorn ourselves with good deeds, like these most holy martyrs, glorifying the Most Holy Trinity, one in three persons – the Father, and the Son, and the Holy Spirit – now and always, and forever. Amen!

Text originally existing in Church Slavonic and translated to Bulgarian language by Archimandrite Dr. Atanasii Bonchev (who was also the Author of the Book the Living of the Saints used in the Bulgarian Orthodox Church even today)

The Menaion (one of Liturgy service books) of the Eastern Orthodox Church lists the names of the Forty Martyrs as follows:

  • Hesychius, Meliton, Heraclius, Smaragdus, Domnus, Eunoicus, Valens, Vivianus, Claudius, Priscus, Theodulus, Euthychius, John, Xantheas, Helianus, Sisinius, Cyrion, Angius, Aetius, Flavius, Acacius, Ecditius, Lysimachus, Alexander, Elias, Candidus, Theophilus, Dometian, Gaius, Gorgonius, Eutyches, Athanasius, Cyril, Sacerdon, Nicholas, Valaerius, Philoctimon, Severian, Chudion, and Aglaius.

A curious fact is in the Eastern Orthodox Church, there is a prayer mentioning the Forty Holy Martyrs of Sebaste is also placed in the Orthodox Wedding Service (referred to as a "crowning") to remind the bride and groom that spiritual crowns await them in Heaven also if they remain as faithful to Christ as these saints of long ago.

Hearing on the enormousness of Saintship of the Holy Fourty Martyrs and their endurance. 
Let us ask them for their holy prayers for more peace, love, faith and hope and endurance and patience on the hard trials each one of us face constantly!

Holy 40 Martyrs of Sebastia Pray the Lord Jesus Christ so we find mercy in God!

Linux show largest sized packages / Which Deb, RPM Linux installed package use most disk space and How to Free Space for critical system updates

Sunday, January 12th, 2020


A very common problem that happens on both Linux installed servers and Desktop Linux is a starting to fill / (root partition). This problem could happen due to several reasons just to point few of them out of my experience low disk space (ending free space) could be due to:

– Improper initial partitioning / bad space planning / or OS install made in a hurry (due to time constrains)
– Linux installed on old laptop machine with low Hard Disk Drive capacity (e.g. 80 Giga / 160 GB)
– Custom user partitioning on install time aiming for a small root partition originally and changing space requirements in time
– Due to increasing space taken by Linux updates / user stored files etc / distribution OS Level upgrades dist-upgrades.
– Improperly assigned install time partitions cause of lack of knowledge to understand how partitioning is managed.
– Due to install being made in a hurry

– Linux OS installed on a Cloud based VPN (e.g. running) in a Cloud Instance that is hosted in Amazon EC2, Linode, Digital Ocean, Hostgator etc.

So here is a real time situation that happened me many times, you're launching an apt-get upgrade / apt-get dist-upgrade or yum upgrade the packages are about to start downloading or downloaded and suddenly you get a message of not enough disk space to apply OS package updates …
That's nasty stuff mostly irritating and here there are few approaches to take.

a. perhaps easiest you can ofcourse extend the partition (with a free spaced other Primary or Extended partition) with something like:

parted (the disk partitioning manipulator for Linux), gparted (in case if Desktop with GUI / XOrg server running)

b. if not enough space on the Hard Disk Drive or SSD (Solid State Drive) and you have a budget to buy and free laptop / PC slot to place another physical HDD to clone it to a larger sized HDD and use some kind of partition clone tool, such as:

or any of the other multiple clone tools available in Linux.

But what if you don't have the option for some reason to extend the paritiotn, how can you apply the Critical Security Errata Updates issued to patch security vulnerabilities reported by well known CVEs?
Well you can start with the obvious easy you can start removing unnecessery stuff from the system (if home is also stored on the / – root partiiton) to delete something from there, even delete the /usr/local/man pages if you don't plan to read it free some logs by archiving purging logs from /var/log/* …

But if this is not possible, a better approach is simply try to remove / purge any .deb / .rpm whatever distro package manager packages that are not necessery used and just hanging around, that is often the case especially on Linux installed on Notebooks for a personal home use, where with years you have installed a growing number of packages which you don't actively use but installed just to take a look, while hunting for Cool Linux games and you wanted to give a try to Battle of Wesnoth  / FreeCIV / AlienArena / SuperTux Kart / TuxRacer etc.  or some GUI heavy programs like Krita / Inskape / Audacity etc.

To select which package might be not needed and just takes space hence you need to to list all installed packages on the system ordered by their size this is different in Debian based Linuces e.g. – Debian GNU / Linux / Ubuntu / Mint etc. and RPM based ones Fedora / CentOS / OpenSuSE


1. List all RPM installed packages by Size on CentOS / SuSE

Finding how much space each of the installed rpm packages take on the HDD and displaying them in a sorted order is done with:

rpm -qa –queryformat '%10{size} – %-25{name} \t %{version}\n' | sort -n

From the command above,  the '%10{size}' option aligns the size of the package to the right with a padding of 10 characters. The '%-25{name} aligns the name of the package to the left, padded to 25 characters. The '%{version} indicates the version and 'sort -n' flag sorts the packages according to size from the smallest to the largest in bytes.


2. List all installed RPM packages sorted by size on Fedora

Fedora has introduced the dnf package manager instead of yum, to get how much size individual rpm package occupies on system:

dnf info samba
Available Packages
Name        : samba
Arch        : x86_64
Epoch       : 2
Version     : 4.1.20
Release     : 1.fc21
Size        : 558 k
Repo        : updates
Summary     : Server and Client software to interoperate with Windows machines
URL         :
License     : GPLv3+ and LGPLv3+
Description : Samba is the standard Windows interoperability suite of programs
            : for Linux and Unix.


To get a list of all packages on system with their size

dnf info * | grep -i "Installed size" |sort -n


3. List all installed DEB packages on Debian / Ubuntu / Mint etc. with dpkg / aptitude / apt-get and wajig


The most simple way to get a list of largest packages is through dpkg


# dpkg-query -Wf '${Installed-Size}\t${Package}\n' | sort -n
6       default-jre
6       libpython-all-dev
6       libtinfo-dev
6       python-all
6       python-all-dev
6       task-cinnamon-desktop
6       task-cyrillic
6       task-desktop
6       task-english
6       task-gnome-desktop
6       task-laptop
6       task-lxde-desktop
6       task-mate-desktop
6       task-print-server
6       task-ssh-server
6       task-xfce-desktop
8       mysql-client
8       printer-driver-all

207766    libwine
215625    google-chrome-stable
221908    libwine
249401    frogatto-data
260717    linux-image-4.19.0-5-amd64
262512    linux-image-4.19.0-6-amd64
264899    mame
270589    fonts-noto-extra
278903    skypeforlinux
480126    metasploit-framework

above cmd displays packages in size order, largest package last, but the output will include also size of packages, that used to exist,
have been removed but was not purged. Thus if you find  a package that is shown as very large by size but further dpkg -l |grep -i package-name shows package as purged e.g. package state is not 'ii' but 'rc', the quickest work around is to purge all removed packages, that are still not purged and have some configuration remains and other chunks of data that just take space for nothing with:

# dpkg –list |grep "^rc" | cut -d " " -f 3 | xargs sudo dpkg –purge

Be cautious when you execute above command, because if for some reason you uninstalled a package with the idea to keep old configuration files only and in case if you decide to use it some time in future to reuse already custom made configs but do run above purge commands all such package saved kept configs will disappear.
For people who don't want to mess up with, uninstalled but present packages use this to filter out ready to be purged state packages.

# dpkg-query -Wf '${db:Status-Status} ${Installed-Size}\t${Package}\n' | sed -ne 's/^installed //p'|sort -n

aptitude – (high level ncurses interface like to package management) can also be easily used to list largest size packages eating up your hard drive in both interactive or cli mode, like so:


# aptitude search –sort '~installsize' –display-format '%p %I' '~i' | head
metasploit-framework 492 MB
skypeforlinux 286 MB
fonts-noto-extra 277 MB
mame 271 MB
linux-image-4.19.0-6-amd64 269 MB
linux-image-4.19.0-5-amd64 267 MB
frogatto-data 255 MB
libwine 227 MB
google-chrome-stable 221 MB
libwine:i386 213 MB


  • –sort is package sort order, and ~installsize specifies a package sort policy.
  • installsize means 'sort on (estimated) installed size', and the preceding ~ means sort descending (since default for all sort policies is ascending).
  • –display-format changes the <you guessed :->. The format string '%p %I' tells aptitude to output package name, then installed size.
  • '~i' tells aptitude to search only installed packages.

How much a certain .deb package removal will free up on the disk can be seen with apt-get as well to do so for the famous 3D acceleration Graphic Card (enabled) or not  test game extremetuxracer

apt-get –assume-no –purge remove "texlive*" | grep "be freed" | 
   awk '{print $4, $5}'

Perhaps,  the easiest to remember and more human readable output biggest packages occupied space on disk is to install and use a little proggie called wajig to do so


# apt install –yes wajig


Here is how to pick up 10 biggest size packages.

root@jeremiah:/home/hipo# wajig large|tail -n 10
fonts-noto-cjk-extra               204,486      installed
google-chrome-stable               215,625      installed
libwine                            221,908      installed
frogatto-data                      249,401      installed
linux-image-4.19.0-5-amd64         260,717      installed
linux-image-4.19.0-6-amd64         262,512      installed
mame                               264,899      installed
fonts-noto-extra                   270,589      installed
skypeforlinux                      278,903      installed
metasploit-framework               480,126      installed

As above example lists a short package name and no description for those who want get more in depth knowledge on what exactly is the package bundle used for use:

# aptitude search –sort '~installsize' –display-format '%30p %I %r %60d' '~i' |head

%30p %I %r %60d display more information in your format string, or change field widths, enhanced format string

Meaning of parameters is:

  • %30p : package name in field width=30 char
  • %I : estimated install size
  • %r : 'reverse depends count': approximate number of other installed packages which depend upon this package
  • %60d : package's short description in field width=60 char

wajig is capable is a python written and idea is to easify Debian console package management (so you don't have to all time remember when and with which arguments to use apt-get / apt-cache etc.), below is list of commands it accepts.

4. List installed packages order by size in Arch Linux

ArchLinux is using the funny named package manager – pacman (a nice prank for the good old arcade game).
What is distinctive of pacman uses libalpm (Arch Linux Package Management (ALPM) library) as a back-end to perform all the actions.


# pacman -Qi | awk '/^Name/{name=$3} /^Installed Size/{print $4$5, name}' | sort -hr | head -25

4. Debian Goodies



Most debian users perhaps never hear of debian-goodies package, but I thought it is worthy to mention it as sooner or later as a sysadmin or .deb based Desktop user it might help you somewhere.

Debian-goodies is sall toolbox-style utilities for Debian systems
 These programs are designed to integrate with standard shell tools,
 extending them to operate on the Debian packaging system.

  dglob  – Generate a list of package names which match a pattern
           [dctrl-tools, apt*, apt-file*, perl*]
  dgrep  – Search all files in specified packages for a regex
           [dctrl-tools, apt-file (both via dglob)]
 These are also included, because they are useful and don't justify
 their own packages:
           – find packages which enhance installed packages [apt,
           – Help to find and restart processes which are using old versions
               of upgraded files (such as libraries) [python3, procps, lsof*]
  debget     – Fetch a .deb for a package in APT's database [apt]
  debman     – Easily view man pages from a binary .deb without extracting
               [man, apt* (via debget)]
  debmany    – Select manpages of installed or uninstalled packages [man |
               sensible-utils, whiptail | dialog | zenity, apt*, konqueror*,
               libgnome2-bin*, xdg-utils*]
  dhomepage  – Open homepage of a package in a web browser [dctrl-tools,
               sensible-utils*, www-browser* | x-www-browser*]
  dman       – Fetch manpages from online service [curl,
               man, lsb-release*]
  dpigs      – Show which installed packages occupy the most space
             – Get list of dbgsym packages from core dump or PID [dctrl-tools,
               elfutils, libfile-which-perl, libipc-system-simple-perl]
  popbugs    – Display a customized release-critical bug list based on
               packages you use (using popularity-contest data) [python3,
             – find which package might have broken another [python3, apt]
             – find which package might have broken the build of another
               [python3 (via which-pkg-broke), apt]

Even simpler by that is to use dpigs shell script part of the debian-goodies package which will automatically print out the largest packages.

dpigs command output is exactly the same as 'dpkg-query -Wf '${Installed-Size}\t${Package}\n' | sort -nr | head', but is useful cause you don't have to remember that complex syntax.


5. Checking where your space is gone in a Spacesniffer like GUI manner with Baobab

In my prior article Must have software on a new installed Windows 2 of the  of the precious tools to set are Spacesniffer and WinDirStat.
Windows users will be highly delighted to know that SpaceSniffer equivallent is already present on Linux – say hello baobab.
is simple but useful Graphic disk usage overview program for those who don't want to mess to much with the console / terminal to find out which might be the possible directory candidate for removal. It is very simplistic but it does well what it is aimed for, to install it on a Debian or .deb based OS.

# apt install –yes baobab


baobab Linux Hard Disk Usage Analyzer for GNOME. – It can easily scan either the whole filesystem or a specific user-requested branch (Iocal or remote)



Baobab / (root) directory statistics Rings Chart pie



baobab – Treemap Chart for directory usage sorted by size on disk 

!!! Note that before removing any files found as taking up too much space with baobab – make sure this files are not essential parts of a .deb package first, otherwise you might break up your system !!!

KDE (Plasma) QT library users could use Qdirstat instead of baobab 

qdirstat-on-gnu-linur checking what is the disk space bottleneck qdirstat KDE

6. Use ncdu or duper perl script tool to generate directory disk usage in ASCII chart bar

ncdu and duper are basicly the same except one is using ncurses and is interactive in a very simplistic interface with midnight commander.

# apt install –yes ncdu
# ncdu /root



# apt-get install –yes durep
# durep -td 1 /usr

[ /usr    14.4G (0 files, 11 dirs) ]
   6.6G [#############                 ]  45.54% lib/
   5.5G [###########                   ]  38.23% share/
   1.1G [##                            ]   7.94% bin/
 552.0M [#                             ]   3.74% local/
 269.2M [                              ]   1.83% games/
 210.4M [                              ]   1.43% src/
  88.9M [                              ]   0.60% libexec/
  51.3M [                              ]   0.35% sbin/
  41.2M [                              ]   0.28% include/
   8.3M [                              ]   0.06% lib32/
 193.8K [                              ]   0.00% lib64/




In this article, I've shortly explained the few approach you can take to handle low disk space preventing you to update a regular security updates on Linux.
The easiest one is to clone your drive to a bigger (larger) sized SATA HDD or SDD Drive or using a free space left on a hard drive to exnted the current filling up the root partition. 

Further, I looked through the common reasons for endind with a disk being low spaced and a quick work around to free disk space through listing and purging larges sized package, this is made differently in different Linux distributions, because different Linux has different package managers. As I'm primary using Debian, I explained thoroughfully on how this is achieved with apt-get / dpkg-query / dpkg / aptitude and the little known debian-goodies .deb package manager helper pack. For GUI Desktop users there is baobab / qdirstat. ASCII lovers could enjoy durep and ncdu.

That's all folks hope you enjoyed and learned something new. If you know of other cool tools or things this article is missing please share.

Howto create Linux Music Audio CD from MP3 files / Create playable WAV format Audio CD Albums from MP3s

Tuesday, July 16th, 2019


Recently my Mother asked me to prepare a Music Audio CD for her from a popular musician accordionist Stefan Georgiev from Dobrudja who has a unique folklore Bulgarian music.

As some of older people who still remember the age of the CD and who had most likely been into the CD burning Copy / Piracy business so popular in the countries of the ex-USSR so popular in the years 1995-2000 audio ,  Old CD Player Devices were not able to play the MP3 file format due to missing codecs (as MP3 was a proprietary compression that can't be installed on every device without paying the patent to the MP3 compression rights holder.

The revolutionary MP3 compression used to be booming standard for transferring Music data due to its high compression which made an ordinary MP3 of 5 minutes of 5MB (10+ times more compression than an ordinary classic WAV Audio the CPU intensiveness of MP3 files that puts on the reading device, requiring the CD Player to have a more powerful CPU.

Hence  due to high licensing cost and requirement for more powerful CPU enabled Audio Player many procuders of Audio Players never introduced MP3 to their devices and MP3 Neve become a standard for the Audio CD that was the standard for music listening inside almost every car out there.

Nowdays it is very rare need to create a Audio CD as audio CDs seems to be almost dead (As I heard from a Richard Stallman lecture In USA nowadays there is only 1 shop in the country where you can still buy CD or DVD drives) and only in third world as Africa Audio CDs perhaps are still in circulation.

Nomatter that as we have an old Stereo CD player on my village and perhaps many others, still have some old retired CD reading devices being able to burn out a CD is a useful thing.

Thus to make mother happy and as a learning excercise, I decided to prepare the CD for her on my Linux notebook.
Here I'll shortly describe the takes I took to make it happen which hopefully will be useful for other people that need to Convert and burn Audio CD from MP3 Album.


1. First I downloaded the Album in Mp3 format from Torrent tracker

My homeland Bulgaria and specific birth place place the city of Dobrich has been famous its folklore:  Galina Durmushlijska and Stefan Georgiev are just 2 of the many names along with Оркестър Кристал (Orchestra Crystal) and the multitude of gifted singers. My mother has a santiment for Stefan Georgiev, as she listened to this gifted accordinist on her Uncle's marriage.

Thus In my case this was (Стефан Георгиев Хора и ръченици от Добруджа) the album full song list here If you're interested to listen the Album and Enjoy unique Folklore from Dobrudja (Dobrich) my home city, Stefan Georgiev's album Hora and Rachenica Dances is available here


I've downloaded them from Bulgarian famous torrent tracker in MP3 format.
Of course you need to have a CD / DVD readed and write device on the PC which nowdays is not present on most modern notebooks and PCs but as a last resort you can buy some cheap External Optical CD / DVD drive for 25 to 30$ from Amazon / Ebay etc.


2. You will need to install a couple of programs on Linux host (if you don't have it already)

To be able to convert from command line from MP3 to WAV you will need as minimum ffmpeg and normalize-audio packages as well as some kind of command line burning tool like cdrskin  wodim which is
the fork of old good known cdrecord, so in case if you you're wondering what happened with it just
use instead wodim.

Below is a good list of tools (assuming you have enough HDD space) to install:


root@jeremiah:/ # apt-get install –yes dvd+rw-tools cdw cdrdao audiotools growisofs cdlabelgen dvd+rw-tools k3b brasero wodim ffmpeg lame normalize-audio libavcodec58


Note that some of above packages I've installed just for other Write / Read operations for DVD drives and you might not need that but it is good to have it as some day in future you will perhaps need to write out a DVD or something.
Also the k3b here is specific to KDE and if you're a GNOME user you could use Native GNOME Desktop app such brasero or if you're in a more minimalistic Linux desktop due to hardware contrains use XFCE's native xfburn program.

If you're a console / terminal geek like me you will definitely enjoy to use cdw

root@jeremiah:/ # apt-cache show cdw|grep -i description -A 1
Description-en: Tool for burning CD's – console version
 Ncurses-based frontend for wodim and genisoimage. It can handle audio and

Description-md5: 77dacb1e6c00dada63762b78b9a605d5


3. Selecting preferred CD / DVD / BD program to use to write out the CD from Linux console

cdw uses wodim (which is a successor of good old known console cdrecord command most of use used on Linux in the past to burn out new Redhat / Debian / different Linux OS distro versions for upgrade purposes on Desktop and Server machines.

To check whether your CD / DVD drive is detected and ready to burn on your old PC issue:


root@jeremiah:/# wodim -checkdrive
Device was not specified. Trying to find an appropriate drive…
Detected CD-R drive: /dev/cdrw
Using /dev/cdrom of unknown capabilities
Device type    : Removable CD-ROM
Version        : 5
Response Format: 2
Capabilities   :
Vendor_info    : 'HL-DT-ST'
Identification : 'DVDRAM GT50N    '
Revision       : 'LT20'
Device seems to be: Generic mmc2 DVD-R/DVD-RW.
Using generic SCSI-3/mmc   CD-R/CD-RW driver (mmc_cdr).
Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R RAW/R16 RAW/R96P RAW/R96R

You can also use xorriso (whose added value compared to other console burn cd tools is is not using external program for ISO9660 formatting neither it use an external or an external burn program for CD, DVD or BD (Blue Ray) drive but it has its own libraries incorporated from libs.

Below output is from my Thinkpad T420 notebook. If the old computer CD drive is there and still functional in most cases you should not get issues to detect it.

cdw ncurses text based CD burner tool's interface is super intuitive as you can see from below screenshot:


CDW has many advanced abilities such as “blanking” a disk or ripping an audio CD on a selected folder. To overcome the possible problem of CDW not automatically detecting the disk you have inserted you can go to the “Configuration” menu, press F5 to enter the Hardware options and then on the first entry press enter and choose your device (by pressing enter again). Save the setting with F9.

4. Convert MP3 / MP4 Files or whatever format to .WAV to be ready to burn to CD

Collect all the files you want to have collected from the CD album in .MP3 a certain directory and use a small one liner loop to convert files to WAV with ffmpeg:

cd /disk/Music/Mp3s/Singer-Album-directory-with-MP3/

for i in $( ls *.mp3); do ffmpeg -i $i $i.wav; done

If you don't have ffmpeg installed and have mpg123 you can also do the Mp3 to WAV conversion with mpg123 cmd like so:


for i in $( ls ); do mpg123 -w $i.wav $i.mp3; done

Another alternative for conversion is to use good old lame (used to create Mp3 audio files but abling to also) decode
mp3 to wav.


lame –decode somefile.mp3 somefile.wav

In the past there was a burn command tool that was able to easily convert MP3s to WAV but in up2date Linux modern releases it is no longer available most likely due to licensing issues, for those on older Debian Linux 7 / 8 / 9 / Ubuntu 8 to 12.XX / old Fedoras etc. if you have the command you can install burn and use it (and not bother with shell loops):

apt-get install burn


yum install burn

Once you have it to convert


$ burn -A -a *.mp3


5. Fix file naming to remove empty spaces such as " " and substitute to underscores as some Old CD Players are
unable to understand spaces in file naming with another short loop.


for f in *; do mv "$f" `echo $f | tr ' ' '_'`; done


6. Normalize audio produced .WAV files (set the music volume to a certain level)

In case if wondering why normalize audio is needed here is short extract from normalize-audio man page command description to shed some light.

"normalize-audio  is  used  to  adjust  the volume of WAV or MP3 audio files to a standard volume level.  This is useful for things like creating mp3 mixes, where different recording levels on different albums can cause the volume to  vary  greatly from song to song."

cd /disk/Music/Mp3s/Singer-Album-directory-with-MP3/

normalize-audio -m *.wav


7. Burn the produced normalized Audio WAV files to the the CD


wodim -v -fix -eject dev='/dev/sr0' -audio -pad *.wav

Alternatively you can conver all your MP3 files to .WAV with anything be it audacity
or another program or even use 
GNOME's CDBurn tool brasero (if gnome user) or KDE's CDBurn which in my opinion is
the best CD / DVD burning application for Linux K3B.

Burning Audio CD with K3b is up to few clicks and super easy and even k3b is going to handle the MP3 to WAV file Conversion itself. To burn audio with K3B just run it and click over 'New Audio CD Project'.


For those who want to learn a bit more on CD / DVD / Blue-Ray burning on GNU / Linux good readings are:
Linux CD Burning Mini Howto, is Linux's CD Writing Howto on ibiblio (though a bit obsolete) or Debian's official documentation on BurnCD.

8. What we learned here

Though the accent of this tutorial was how to Create Audio Music CD from MP3 on GNU / Linux, the same commands are available in most FreeBSD / NetBSD / OpenBSD ports tree so you can use the same method to build prepare Audio Music CD on *BSDs.

In this article, we went through few basic ways on how to prepare WAV files from MP3 normalize the new created WAV files on Linux, to prepare files for creation of Audio Music CD for the old mom or grandma's player or even just for fun to rewind some memories. For GUI users this is easily done with  k3b,  brasero or xfburn.

I've pointed you to cdw a super useful text ncurses tool that makes CD Burninng from plain text console (on servers) without a Xorg / WayLand  GUI installed super easy. It was shortly reviewed what has changed over the last few years and why and why cdrecord was substituted for wodim. A few examples were given on how to handle conversion through bash shell loops and you were pointed to some extra reading resources to learn a bit more on the topic.
There are plenty of custom scripts around for doing the same CD Burn / Covnersion tasks, so pointing me to any external / Shell / Perl scripts is mostly welcome.

Hope this learned you something new, Enjoy ! 🙂
