using wordpress CLI to post to wordpress

2011-03-24 1 min read Bash Wordpress

There is a very nice post here: How to post content to a WordPress blog from the command line

I tried this in Fedora 14 and here is the way to get this working in Fedora

  <td>
    <div class="text codecolorer">
      su -<br /> <br /> cpan<br /> <br /> install WordPress::CLI WordPress::Post
    </div>
  </td>
</tr>

Now, once the above completes make sure that the path /usr/local/bin is in you path.

Try all colors in xterm with script before setting the color

2011-03-18 2 min read Bash Fedora Learning Linux

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

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.

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

2011-03-09 9 min read Bash Fedora Learning Linux Vim Tips

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:

print every nth line

2011-03-01 2 min read Bash Linux

Some time back I was working with lot of data and wanted to analyze only the every 10 line sometimes and sometimes every 20th line. I had to keep doing these changes in vim or otherwise so finally I wrote a program to do this for me. If you need such a program then here it is:

  <td>
    <div class="text codecolorer">
      #!/bin/bash -<br /> #===============================================================================<br /> #<br /> #          FILE:  print_nth_line.sh<br /> #<br /> #         USAGE:  ./print_nth_line.sh<br /> #<br /> #   DESCRIPTION:  Print every nth line<br /> #<br /> #       OPTIONS:  ---<br /> #  REQUIREMENTS:  ---<br /> #          BUGS:  ---<br /> #         NOTES:  ---<br /> #        AUTHOR:   (),<br /> #       COMPANY:<br /> #       VERSION:  1.0<br /> #       CREATED:  12/08/2010 05:36:53 PM IST<br /> #      REVISION:  ---<br /> #===============================================================================<br /> <br /> if [ x"$1" == "x" ]<br /> then<br /> echo "Please provide the line numbers to print .. .ex 3 will print 3,6,9"<br /> exit -1;<br /> fi<br /> if [ x"$2" == "x" ]<br /> then<br /> echo "Please provide the filename"<br /> exit -2;<br /> fi<br /> awk 'temp++ { if ( temp % '$1' == 0) print $1};' $2
    </div>

/bash debugger

9.2. A bash Debugger

In this section we’ll develop a very basic debugger for bash.[10] Most debuggers have numerous sophisticated features that help a programmer in dissecting a program, but just about all of them include the ability to step through a running program, stop it at selected places, and examine the values of variables. These simple features are what we will concentrate on providing in our debugger. Specifically, we’ll provide the ability to:
