Try all colors in xterm with script before setting the color

If you are looking for testing the colors on how they would look like in the xterm before you set the color then here is a small script for you.

  <td>
    <div class="text codecolorer">
      #!/bin/bash -<br /> #===============================================================================<br /> #<br /> #          FILE:  xterm_colors-test.sh<br /> #<br /> #         USAGE:  ./xterm_colors-test.sh<br /> #<br /> #   DESCRIPTION:  Test all the colors for xterm bg<br /> #<br /> #       OPTIONS:  ---<br /> #  REQUIREMENTS:  ---<br /> #          BUGS:  ---<br /> #         NOTES:  ---<br /> #        AUTHOR:   Amit Agarwal (amit.agarwal@amit-agarwal.co.in), aka<br /> #       COMPANY:  Individual<br /> #       VERSION:  1.0<br /> #       CREATED:  02/18/2011 01:02:51 PM IST<br /> #      REVISION:  1.0<br /> #===============================================================================<br /> <br /> cat /usr/share/X11/rgb.txt |sed 's/\([0-9]\{1,3\}[ \t]*\)\{3\}//'|sed 's/^ *//' >~/rgb.txt<br /> while read line<br /> do<br /> bg=$(echo $line)<br /> echo $line<br /> echo "Trying $bg color"<br /> xterm -bg "$bg"&<br /> sleep 5<br /> kill -9 $!<br /> done < ~/rgb.txt
    </div>
  </td>
</tr>

This can be used in various ways but I will leave the choice to you. One option that I should probably still tell is :

cd across parallel directories

Here is a simple and fast way to cd across parallel directory.

  <td>
    <div class="text codecolorer">
      cd ${PWD/test/actual}
    </div>
  </td>
</tr>

Using ssmtp to send mail using gmail.

First install the package ssmtp using the command:

hostname=**username**@gmail.com

AuthUser=username
AuthPass=password

In order to make the default (root) “from” field be the server name,
edit the /etc/ssmtp/revaliases file as root user :

vino – connect to running GNome session like RDP

One thing that all of us Linux users have probably missed is connecting to the running GNome session to see what is going on in the running session. This can be quite handy in couple of situations:

1. Debugging remote sessions – where you do not want a new session, instead want to connect to running session.

2. Maintaining running session from another PC. If you are running some applications on some Linux box and want to gracefully stop it using some commands other than kill -9 then it is best that you connect to the running session, if you are not using screen.

shopt causes bash completion to stop working.

Couple of days, I added some scripts to my bash startup and suddenly realized that bash completions stopped working. This is tricky situation in bash to figure out what went wrong. So, I set my foot down to make sure that I find out the culprit. Thus I started with method of elimination. So, I started with nothing in .bashrc and kept adding my stuff in batches, until the said feature was broken. Once that happened I started removing the added ones, one by one, until my completion started working again.
