How to add repository manually from command line in Ubuntu Linux

Sunday, January 8th, 2012

I'm on a way trying to install Free Mega Games Pack and I'm facing troubles in following the instructions to add a the latest development wine version described on
The guys from WineHQ has to update the wine install instructions, since the instructions are targetting older versions of Ubuntu which are not compatible with newer Ubuntus which comes natively with Unity
In order to complete the step in adding the WineHQ Ubuntu PPA development repository my only way was to add it using command line.
Here is how:

root@ubuntu:~# apt-add-repository ppa:ubuntu-wine/ppa
You are about to add the following PPA to your system:
Latest official WineHQ releases
Welcome to the Wine Team PPA. Here you can get the latest available Wine betas for every supported version of Ubuntu. This PPA is managed by Scott Ritchie, and is a replacement for the WineHQ repository used for Jaunty and earlier.
More info:
Press [ENTER] to continue or ctrl-c to cancel adding it
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.bvo21sFWKG --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp:// --recv 883E8688397576B6C509DF495A9A06AEF9CB8DB0
gpg: requesting key F9CB8DB0 from hkp server
gpg: key F9CB8DB0: public key "Launchpad PPA for Ubuntu Wine Team" imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)

Similarly adding a PPA repository on Debian is also possible by using a little shell script . simulates what ubuntu's apt-add-repositry python script does.

It is educative to mention PPA stands for (Personal package Archive) and the difference between normal repository and PPA is mainly in the fact that PPA repositories makes a package distributed by the repository like the native Ubuntu packages issued by Canonical.
Once for example a new version of a file is placed in PPA deb package repository, the newer package will be automatically installed to the system using it.

How to add multiple email accounts in qmail’s vpopmail with vpasswd via ssh (console) / Little shell script to add multiple email addresses

Sunday, June 12th, 2011

I’ve been assigned the task to add on one of the qmail powered servers I administrate about 50 email addresses via command line.

Each email addresses was required to be configured to have the same mail password.
Adding the email addresses via an interface would be a killing time consuming task and will probably require at least 1 hour of time to add the emails with qmailwebmin, qadmin, qubit or the other vpopmail qmail web administration interfaces available nowdays.

To solve the task, I’ve used a line oner bash shell script which reads all my 80 emails from a file and adds them with vpopmail’s command line tool vpasswd on the mail server.

Here is the one liner shell script I’ve written to solve the task:

debian:~# while read line; do vadduser $line Email_Pass_Phrase; done < email_list_file.txt

In above’s code I’ve used the email_list_file.txt file is a text file on the server and contains list of all my 50 email addresses, where each line in the file contains one email. The Email_Pass_Phrase is actually the password I’ve set for all the new email addresses being created with vpasswd

That’s all now the 50 email addresses on the server are created and I’ve saved at least one hour of boring repeating actions in the browser 😉
