Any way to create bash short cuts (like CTRL+l for clear and Ctrl+D for exit)

as the subject says ...
i want to create short cuts for some commands like these ones..
(it shud be possible as Ctrl+l executes the clear command)
Ctrl+Shift+Delete-->ps aux
Ctrl+Left --->cd $OLDPWD
Ctrl+Up--->cd ..

If those keys produce some text (like Ctrl+C produces ^C) You should be able to alias them in your user's .bashrc.

I'm not sure if it is possible and I really can't try at the moment but see if it works.

You can find more information on aliases here:http://www.ss64.com/bash/alias.html

If you want to do this in a shell script, consider reading user input and then checking their ASCII values. For example ctrl + a = 01 in ASCII and ctrl + b = 02 in ASCII.

Alright here is the solution. In order to bind keys in bash you need to add entries for those bindings in the /etc/inputrc file. For example the following entry maps CTRL-o to cd $OLDPWD

"\C-o": 'cd $OLDPWD\n'

Similarly the following entry would bind CTRL-l to ls:

"\C-l": 'ls\n'

Hope this helps.
