The Ultimate Guide to Getting Support on Linux
Installing Linux has become effortless to the extent that anyone with a little knowledge of computers can get a Linux machine up and running instantly. However, many of them throw in the towel when faced with even the slightest of glitches. The main reason for this is the belief that Linux doesn’t offer any kind of support.

Other problem users face is that the regular technician who repairs their computer refuses even to touch a machine that’s running Linux. So, if you are one of those users disgruntled after encountering a multitude of problems with a fresh Linux install — don’t panic and read on to know some ways in which you could get support for your Linux installation.

vim autocomplete – automagically without tab.

Lets first do the setup in one line. Get my vim script downloader.

Use the script to add the script with script ID : :1879 (vim-autocomplpop) to your list of plugins for vim and you  are done.

If you are using snipmate, then make sure that you read the description of the plugin to add the required lines to the vimrc file to get the full functionality. You would love to type henceforth in your favourite editor. We will talk about more on Intellisense in few days time.. Chao till then.

Easy ssh configuration with .ssh/config file

If you ssh to many hosts then you are aware of the pain that it takes to ssh with different username and hostname. There is an alias that you can creat with native ssh though. Here I will show you the same with an example.

  <td>
    <div class="text codecolorer">
      cat <<EOF >>~/.ssh/config<br /> Host <alias><br /> Username <user name><br /> Port <port number><br /> Hostname <hostname>
    </div>
  </td>
</tr>

You can optionally omit the parameters that you do not require explicitly. For example, if your port number is default then you can simply ignore the parameter.

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 :

what is vim in 6Kb..

If you thought that vim is very bloated and nothing abuot this editor can be small, then you are not alone. I was myself in the same bandwagon.

Well, I never thought that there could be anything about vim that can be explained in Kb’s, lest alone the complete vim features. But looks like vim.org had thought about this and thus came up with this. And here is the direct link to the vim in 6kb in English.

All in one solution for all the scripts of vim from vim.org

For quite sometime now, I was looking for some console based program which would help me get the scripts from vim.org. A simple solution would have been to do a wget for the scripts. But since there are so many scripts coming up daily and with a need to search based on script ID and name of the script, I thought better to write a script that can do all of those things. Now, what was required was that the script should be either able to download this or add to the GLVS script. Also note that, I had done something similar in the past here. There are some additions in the below script. You can download a copy of the script get_vim_scripts. Or you can copy the script from below:

using gnuplot for time plotting

Couple of days back, I was working with some data and wanted to plot it. I had couple of options Excel, ploticus and then our own gnuplot. My choice here was gnuplot, as this is most commonly available and helps me write scripts that can automate my repetitive task. So far, so good. The data I was plotting was against time, that was the problem. Couple of quick searches did not result into any luck to get me on the path and hence with some man pages and some documentation, finally I found this, might be this will be helpful for others.
