1. Gnome Appearance modify command  in Linux instead – Intro

It is always handy to do stuff in console and as a GNU / Linux long time GNOME user I found it interesting to share here some nice tips on how Theme could be changed using command line.

Why would you ever want to change themes through console / Terminal? Well lets say you have to administrate remotely a bunch of GNU / Linux Desktop machines and you have to change themes simultaneously on a multiple hosts, changing theme using the command line then comes really handy.

Besides that in GNOME 3.X.X branch with Unity (yackes) if you have chosen to use GNOME (Flashback /Fallback) or Mate you might find it difficult to change some specifics of the default theme, that is especially true for GNOME (flashback) Fallback like me.

If you heard GNOME Flashback but you never used i and wonder what it is I think it is worthy to say few words about it:

GNOME Flashback is a session for GNOME 3 which was initially called "GNOME Fallback", and shipped as a stand-alone session in Debian and Ubuntu. It provides a similar user experience to the GNOME 2.x series sessions. The differences to the MATE project is that GNOME Flashback uses GTK+ 3 and tries to follow the current GNOME development by integrating recent changes of the GNOME libraries. The development currently lags behind a little but a lot of progress has been made in bug fixing lately. So in short GNOME Fallback is for anyone who wants to stick to GNOME 2.X interface but doesn't want to stick to Mate and wants still to use some more graphical goodies that comes with GNOME 3.

In MATE nowadays there is possibility to relatively Easy add / change appearance and add new themes, there is also the graphical tool called Appearance accessible via mate-control-center command or menus. Using Appearance you can modify themes and Window Decorations, however there is much more that can be done or tuned missing in the MATE GUI using a couple of GNOME desktop environment native commands.

3. Change GTK Theme


Below commands are for GNOME 3 based desktop environments this includes also any other GNOME based Graphical Environments or components of GNOME 3 such as (Ubuntu Unity, GNOME 3 Shell/Classic, Cinnamon), and even the old GNOME 2 desktop.

In GNOME 2 it was possible to set various variables directly from gconf-editor including GTK Themes but in GNOME 3 somehow this is no more … so to do we need to use some cryptic commands or use gnome-tweak-tool or MyUnity (Ubuntu Linux users with Unity) but configuration that can be made with them is unfortunately partial so in any case knowing below commands is a necessity to be able to tune up nicely your Linux Gnome Desktop.

And yes it is crazy why on Earth gnome developers scaped out the configuration from gconf-editor and left us with this user unfriendly method. Could it be that someone (Like the big corporations) has the interest to ruin Free Software?? What do you think…
 

Unity, GNOME 3 Shell/Classic, Cinnamon

In Unity GNOME 3 Shell / Classic and Cinnamon (the default Debian graphical env).

Before we start I recommend you check out what is the current installed and enabled theme, you might want decide to keep it after checking the number of themes available. To check your current installed GNOME theme run:

 

gsettings get org.gnome.desktop.interface gtk-theme
'Adwaita'


You see I have 'Adwaita' theme as a default.
Next lets change the gnome GTK theme interface.
 

gsettings set org.gnome.desktop.interface gtk-theme "Menta"

 


MATE (In Linux Mate the current fork of GNOME 2 for hardcore GNOME 2 users)

 

mateconftool-2 –type=string –set /desktop/mate/interface/gtk_theme "Menta"

 


GNOME 2 (In native GNOME 2 if you still own some old machines with old Debian / Ubuntu / Fedoras etc.

 

 

gconftool-2 –type=string –set /desktop/gnome/interface/gtk_theme "Menta"

 


4. Change WINDOW THEME (Metacity)
 

Unity, GNOME 3 Classic (Metacity), GNOME 3 Shell (Metacity > Mutter)

 

gsettings set org.gnome.desktop.wm.preferences theme "Menta"


Cinnamon (Metacity -> Muffin)

 

gconftool –type=string –set /desktop/cinnamon/windows/theme "Menta"

 

Note: Cinnamon must be restarted for the change to take effect.


GNOME 2 (In Gnome 2 with Metacity)

 

gconftool-2 –type=string –set /apps/metacity/general/theme "Menta"

 


MATE (Metacity)

 

mateconftool-2 –type=string –set /apps/marco/general/theme "Menta"

 


Change SHELL THEME (In Gnome Shell and Cinnamon)


GNOME Shell (user-theme extension must be enabled)
 

gsettings set org.gnome.shell.extensions.user-theme name "Menta"


Cinnamon

 

gsettings set org.cinnamon.theme name "Menta"

 


5. Change GTK COLOR SCHEME

Unity, GNOME 3 Shell/Classic, Cinnamon (Change GNOME3 Color scheme)

 

 

gsettings set org.gnome.desktop.interface gtk-color-scheme "bg_color:#e9efe9;fg_color:#444444;base_color:#ffffff;text_color:#333333;selected_bg_color:#6666cc;selected_fg_color:#eeeeee;tooltip_bg_color:#222222;tooltip_fg_color:#dfcfcf;link_color:#cc0099;"

Reset color (if you don't like it):

gsettings set org.gnome.desktop.interface gtk-color-scheme ""

 

MATE (Mate set color scheme)

 

 

mateconftool-2 –type=string –set /desktop/mate/interface/gtk_color_scheme "bg_color:#e9efe9;fg_color:#444444;base_color:#ffffff;text_color:#333333;selected_bg_color:#6666cc;selected_fg_color:#eeeeee;tooltip_bg_color:#222222;tooltip_fg_color:#dfcfcf;link_color:#cc0099;"

 

 

Reset color :

 

mateconftool-2 –type=string –set /desktop/mate/interface/gtk_color_scheme ""

 


6. GNOME 2 (Again for the old GNome 2 machines to change the GTK Color scheme)

 

gconftool-2 –type=string –set /desktop/gnome/interface/gtk_color_scheme "bg_color:#e9efe9;fg_color:#444444;base_color:#ffffff;text_color:#333333;selected_bg_color:#6666cc;selected_fg_color:#eeeeee;tooltip_bg_color:#222222;tooltip_fg_color:#dfcfcf;link_color:#cc0099;"

 

Reset color:
 

 

gconftool-2 –type=string –set /desktop/gnome/interface/gtk_color_scheme ""

 


What about colors, well the #444444 and #22222 and #eeeeee, #333333 seen as color codes in above examples can easily decrypted if you don't know them using a tiny tool called gcolor2
The tool is installable on most Linux distributions with a simple apt-get install gcolor2 or yum install gcolor the tool is convenient and a must have for anyone using Linux for basic design or graphic operations with some program as GIMP / Krita / Inkscape / Vectr / Karbon etc.

All gcolor2 does is to make easy for you to get HTML color codes and convert existing ones into colors for you, here is shot:

https://ubuntuforums.org/showthread.php?t=1778355

While talking about setting color another interesting Graphical tool related to article, that gives you abilities to change colors in GNOME is gnome-color-choose, the tool is really awesome and allows you to do many of the color tunings shown in above examples

# apt-get install –yes gnome-color-chooser

And finally for the gnome theme hungry people, here is a great bonus. If you need a ton of shiny new themes as possibility to set up on your GNOME download and install The Ultimate Edition Themes deb (Debian / Ubuntu Mint) etc. collection (mirrored):

Debian and other deb based distro users can easily download and install with:
 

linux:~# dpkg -i ultimate-edition-themes-.0.0.7_all.deb

 


Other Linux users such as Fedora ones and Slackware users (if anyone on Slack uses Gnome since KDE is default by default there), use alien tool to install it or directly open the file with Midnight Commander (mc) and copy the files to the /usr/share/themes dir.

 

This article is possible thanks to Change Theme Using Command Line in GNOME (Linux) command line examples are taken from there.

How to colorize your Mac OS X Terminal – Beautify your Mac OS terminal and proper Page Up / Page Down and Home / End bindings

Thursday, March 19th, 2015


If you're a sysadmin (like me) or a programmer and love working on console most of the time on a recently bought Apple (Mac) PC, probably not like that by default Terminal App lacks nice color highlighting, color highlighly is already standard on Ubuntu / Debian / Mint and many of the streamline Linux distros for years, so it's weird that the shiny Mac lacks that in console 🙂
 I'm not blaming Mac OS developers for shipping by default Mac's console so much greyish as most Mac userbase almost never use terminals, however adding some appearance candy makes my boring digital life much more entertaining.

beautify-add-colors-to-Mac-OSX-default-app-program-add-shiny-clolors-improve-mac-os-x-terminal-screenshot.png

Put in your home directory $HOME/.profile or in .bash_profile file below code:

 

vim ~/.profile
PS1='\[\e[0;33m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '
export PATH="/opt/local/bin:/opt/local/sbin:$PATH"
export CLICOLOR=1
export LSCOLORS=ExFxBxDxCxegedabagacad
alias ls='ls -GFh'

 

echo "PS1='\[\e[0;33m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '
export PATH="/opt/local/bin:/opt/local/sbin:$PATH"" >> ~/.profile

echo "export CLICOLOR=1" >> ~/.profile
echo "export LSCOLORS=ExFxBxDxCxegedabagacad" >> ~/.profile
echo "alias ls='ls -GFh'"  >> ~/.profile

 


PS1 with above string do colorize Terminal's default “username@hostname:cwd $” following alias makes by default ls (dir) command to have colors enabled (show files and folders in shiny colors like on GNU / Linux). As you see the ls command perameter -G which actually adds colors is the same like in FreeBSD (since very big part of Mac OS is based on BSD UNIX utils), -F makes directories to be marked with / and -h (stands for human readable).
If you want to enable terminal ls colors for all existing Mac computer users open /etc/profile and (uncomment) / include:

 

export CLICOLOR=1
export LSCOLORS=GxFxCxDxBxegedabagaced

 


If you want to customize further Mac OS's default Terminal App (add different Colorize Theme), change default shell, change default Title, add Transparency, Change Term Encoding etc.  go and check settings in:
 

Terminal -> Settings


Mac-OS-default-Terminal-shell-settings-interface-change-theme-mountain-lion-screenshot
One really annoying thing about Mac OS X terminal for being users is that by default Command + D which is like CTRL + D on a non-Mac PC sends Split Window command, splitting the screen by two,  if you're a new Mac user like me you will have to get used to Command + Shift + D which is the Mac equivalent of regular PC keyboard CTRL + D. Note that it is not possible to move between Splitted screens but instead the upper part of the split screen is just like a buffer where old output from terminal is put and can be used to keep an eye constantly on old content displayed on terminal …
If you're too lazy to edit files and stuff and just want to receive already well configured Terminal which has many of the features of gnome-terminal / konsole which are not there in  Mac's default Terminal App, just download and use iTerm2 (OS X Terminal Replacement)

iterm2-mac-osx-mounta-lion-10.8.5-best-terminal-application-for-mac-OSX-screenshot

Once over with Terminal customizations if you happen to use VI Improved (VIM) text editor as an editor of choice on Mac create at least following .vimrc in your HOME directory
 

$ vim ~/.vimrc

" End
map <C-E> <End>
imap <C-E> <C-O><End>

" Home
map <C-A> <Home>
map <C-A> <C-O><Home>

 


This maps Command + A / Command + E to (emulate) act like normal PC Home / End Keyboard key button, to emulate Page Up / Page Down keys on Mac OS keyboard inside Terminal app use Fn (key) + Up / Down arrows.
To make HOME / END buttons answer to Control + A / E on a Terminal App level:

 

Inside Terminal.app
Open the Preferences window (CMD+,)
Click the Settings tab
Select your current Settings theme, and click on the Keyboard tab
Edit (or Add) the entry for Home
Set Action: to send string to shell:
Set the string to \001 (or press Ctrl+a)
Edit (or Add) the entry for End
Set Action: to send string to shell:
Set the string to \005 (or press Ctrl+e)
Edit (or Add) the entry for Page Up
Set Action: to send string to shell:
Set the string to \033[5~ (copy and paste this in)
Edit (or Add) the entry for Page Down
Set Action: to send string to shell:
Set the string to \033[6~ (copy and paste this in)
Close the settings window.

Color Trick Microsoft and Google use to keep their users loyal and happy unwalfully

Tuesday, June 12th, 2012

Color mind influence has been longly researched. It is researched and there are some findingings on how we people react on colors. This researches are not much known and most of them are not put on the internet (??) One model claiming to have explained how colors influence is called HBDIHerrmann Brain Dominance Instruments.

In the picture beginning of this post, I have presented a quick "Personal Profile" of HBDI on how one think in order to determine in "which colors" one tends to think more ___

In short HBDI model claims to explain how people think in another model.
My personal view of it is it is like most science nowdays more based on faith than on a clearly conducted scientific research and facts. We know pretty well many people tried to explain how brain operates and many people give models to explain it however none of the models could grasp in completeness the complexity of human brain. Hence Businessman people who use this model in their daily life and they push it to us has put the model in action not that they know it is working but rather they believe it does .., Saying this few words as introduction I will contninue onwards to explain you about HBDI as in the business world it is considered as a "Strategic Asset" for a company success. Hence the use of richest companies of the model has a serious impact on us the common people and unknowing (uninformed) computer users.

Some of the companies who integrated the HBDI to their models we all know are of course not strangely Microsoft and Google
;;;

Below I present you a picture showing the HBDI The Whole Brain Model |||

HBDI The whole brain model

Next I show you Microsoft Windows OS worldly "infamous" flag |||

Microsoft Windows OS Flag

You can see for yourself the basic color from HBDI WHOLE brain model are integrated in the Microsoft flag, only the order of colors present and the color gamma is different;;;;

The basic colors in HBDI model to explain how human brain works is separated in 4 segments as you can see from above screenshot. There are a number of tests one can do to determine what is his exact HBDI profile, and in abstract terms in which kind of colors he prefers to think.

There are a whole "army" of people involved into this sect like philosophy (I call it philosophy as surely every model that tries to explain everything is doomed to fail it is the nature in which God created the universe so complex and he put us be part of it and not controllers of it that any Universal model trying to explain it has never succeeded so far. The HBDI has some fruits for the only reason it is believed to work well by the people with money.

As you see in the colors HBDI claims there are 4 segments corresponding to four basic colors

  • BLUE
  • YELLOW
  • GREEN
  • RED

Each of the colors is an indicator on how the person tends to think the BLUE people as HBDI practicioners (believers) calls them are —

Analytical, Fact Based, Logal, Quantitative

The YELLOW oriented people are claimed to be —

Holistic, Intuitive, Integrating, Synthesizing

The GREEN ones in model terms are interested in —

Organizing, Sequentiality, Planning, Detailizing facts

Finally the RED Ones are said to be —

Interpersonal, Feeling based, Kinesthetic, Emotional

Now as you can understand this model though it looks like promising is based on a philosophy which rejects the existing of spirit realm God Angels or good or evil. It claims everything we're are or we want to be can be achieved following the HBDI to develop your own brain.

This model as every human made model however does reject the fact that besides internal factors and brains we're put into external environment most of which we cannot control and therefore even if we try our best to have certain goals and complete them the external uncontrolled facts can be a reason to stop us to complete our goals.

Now back to my point, that Google, Microsoft and probably many other products and physical goods are heavily using the HBDI color scheme ;;;
Here is the Google Inc. Logo the color trait of HBDI is there:

Google Search Engine Logo and HBDI 4 colors embedded

For those doubting that Google Inc. and Microsoft Inc. are along the false believers of HBDI color scheme brain ideology I present below the Logo of Google Web Browser =- Google Chrome

Google Web Chrome Browser Logo 4 colors HBDI microsoft flag

It is evident 4 colors used as a main ones in the HBDI tool are present in Google Chrome just like in Microsoft Windows logo flag, the only difference is in the order of colors.
Also it is interesting the name Chrome that Google Chrome took is most likely taken from Aldous Huxley's – Brave New World (A book depicting a short future highly conditioned society) , the book story line goes around a society programmed to do the things they do.

I assume it is very likely that Google's founders Sergey Brin or some of their subordinate working for Google are very much into the idea of conditioning people just like in the book and this is most likely the reason they choose the Chrome as a title for Google's browser ,,,

The 4 Colors from HBDI yellow, green, blue, red are embedded also in the google .ico file (the little icon showing in browser URL bar), below is a screenshot of a tab where google is opened showing the .ico image:

Google Icon 4 colors Linux Debian Epiphany Browser tab screenshot

Do you remember the good old Windows XP start button, have you noticed the Windows flag embedded in it, if not let me show you;;;

Microsoft Windows XP Start Button and HBDI 4 colors scheme

But wait the Windows flag placed on the left bottom of Ms Windows-es is not only on XP it is also on Windows 3.11 cover, Winblows 98, Vista, Windows 2003, Windows 2007 and actually all the M$ operating systems ever produced since the very early days M$ become a top OS producer :::

Windows 3.11 Operating system logo flag

Microsoft Windows 95 4 colors flag and blue sky

Here is also the 4 colored (a bit like Nazi like looking) flag on M$ Win-doze 7 |||

MS Windows 7 start Menu m$ windows well known flag

Also the Microsoft Flag is positioned on the bottom left screen on purpose. It is well known fact that most of the world (except Arabic) are used to read the text from Left to Right

, therefore it is natural for our eyesight to look for the text on the left side. I just wonder why they placed the START on the bottom and not on top. It is natural we read text and books from the most top to the most bottom ,,,.,

Even Apple Computers nowdays Macs has most likely used the HBDI as the main 4 colors and some gamma from rainbow colors are present on their Classical Apple Computer logo

Old Apple Computer/s logo colors of rainbow 4 hbdi colors are there

Makes me wonder if Jobs employed the HBDI model in his company. Well what is the reason for people loving so much this rainbow colors combination. If we think for a second outside of HBDI's brainwashing ideology for what each color would stand for. Well it is simple is comes from our young years most of the people between age 2 and 50 years has been more or less exposed to the so colorful Kids Cartoons, which are all so colorfully painted. Since our very early age we've placed in us a love for colorfulness outlook (well again not all of us for example I prefer less colors, I'm sure there are plenty of people who don't like the heavy colors we see in almost everywhere around us).

The problem with this 4 colors use on purpose and all this unnatural color placing everywhere is that it is unnatural and not in good synergy with our surrounding natural environment. Therefore I personally think using a colorful color paintings on everywhere in both computer programs and the physical world plays us a bad joke and is one of the reasons so many people are on the virge to get crazy nowdays and many have already had already cracked out.

It is my firm believe more and more people should be educated on the harm of HBDI and the fact that, we're forced to 'live it' unwilfully every day by using even as "simple things" as computers and daily technology or buying food in the super market ,,,
