Get Examples for Random Bash Commands

Following my post about a script to query bash commands from shell-fu, here is another script, which queries shell-fu for examples of a random bash command:

The script is not bullet-proof and might fail if the guys at shell-fu decide to change the website’s layout, but it works for now, and this is good

Open a new text file and type this:

1
2
3
4
#!/bin/bash

PAGER="/usr/bin/less -rXF"

lynx -width=$COLUMS -nonumbers -dump "http://www.shell-fu.org/lister.php?random" |\

sed -n '/Tailrank/,/View Comments/p' shrnd.tmp | sed '$d' | sed '1,2d' | $PAGER

Now save the file as shexrand, or any other name (shexrand is for shell example – random)

Make the file executable:

chmod +x shexrand

Now move the file to /usr/local/bin

Thats it, to use it, just type:

shexrand

and you should get an example of a random bash command.

Enjoy
