Get Examples for Bash Commands in Your Terminal

This one is by the great shell-fu, a website with many bash examples.

The following script is a powerful enhancement for the bash experience, and a great addition to the manpages, it allows you to query shell-fu for examples about almost any bash command you might want to use.

The following code is by shell-fu and is available here.

In order for this to work, you’ll need to have “lynx” – the command-line web browser. You can install it in Ubuntu with this command:

sudo apt-get install lynx

Here is the code:

Open a new file and type this:

1
2
3
4
#!/bin/bash

lynx -width=$COLUMNS -nonumbers -dump "http://www.shell-fu.org/lister.php?tag=$1" | \

sed -n '/^[a-zA-Z]/,$p' | egrep -v '^http|^javas|View Comm|HIDE|] \+|to Share|^ +\*|^ +[HV][a-z]* l|^ .*efu.*ep.*!$' | \

sed -e '/^  *__*/N;s/\n$//g' | \less -rX;

Save the file as sheg (or any other name, sheg stands for shell examples)

Now make the script executable:

chmod +x sheg

Now move the file to /usr/local/bin

That’s it, you can use the script like this:

sheg bc

Or

sheg sed

Enjoy
