I'm not sure what you are after. A custom program can be anything from a program written in a higher language (C, JAVA, ...), a script (Perl, awk, bash, ...) or even an alias or function based on an already existing program.

The example you give can be accomplished by an alias:

Code:

alias sd='shutdown'

Add this alias to your /etc/profile (for global usage) or in ~/.bashrc to make it local.

If this is not what you are after then please explain a bit more.

BTW: The shutdown command needs root permissions.

In that case you need to learn C++

There are many on-line articles that can help you. Feed your search engine with Linux C++ Programming HOWTO and take your pick.

EDIT: Looking for something else I just ran into this right here at LQ: C/C++ TUTORIALS
