[Linux] How to make your own program also supports auto-complement (bash environment) __linux

You wrote a command-line program called NB, and you want the tab to automatically list the prompts you want after bash enters NB spaces.

Or you want to be able to list all the names of the machines you have permission to connect to by the Space tab after bash has entered SSH.

Or more directly, you've written a Nb_ls program that's more NB than the system's own, and then you want it to be fully functional like LS.

Bash Complete is doing this, and it can support custom completion.

This article describes the detailed setup method: http://www.blogjava.net/sean/archive/2009/06/01/279316.html

(bash complete can actually specify ' any output of any program ' as a hint or a full complement of content)
