When in bash, I can type the beginning of a command name (which is not necessarily in the current directory), hit tab a couple times, and a list of commands is displayed which start with what I have typed (almost looks like the list is being displayed with 'more', but I have to press Enter to scroll down the list).

My question is this, how does this functionality work? I want to be able to get a list of all commands that are auto-complete-able via hitting tab twice, so that I can pipe it to a file or grep.

Well, I was able to come up with a script to somewhat do this, I put the script in the snippets at http://www.dreamincode.net/code/snippet1537.htm

It doesn't do everything though, because if there are some built in bash commands, this script won't find them.

Why can't you just run a find with the start of the file name, against your path, or /usr/bin,/usr/sbin & pipe that with grep? Or an ls...?

Right, that is what I want to do, but I want to do it for every directory in my $PATH. I read through the man page for find a couple times and couldn't find an option that would accept a list of directories.
