Get all commands from unix

[Yadagiri Rao KP]

I am doing a assignment which involves getting all possible unix
commands and add to to a list box.
Firstly I used Runtime and Process classes and used the "env" as an
arguement to process.
but where all commands are stored in order to retrieve?
pls help

Try to list the files under /bin/

Get the PATH variable, a list of directories separated by ':'. The
possible commands for the current user are found in those directories.
You'll probably also need to consider the permissions associated with
each executable along with the identity (user and groups) of the
current user, since the existence alone of a file in one of those
directories doesn't mean that you can run it.

That still won't get all commands inherent in the user's shell - not
all of them need exist in program form.

A potential solution could be to scan the files in "man" section 1.

Look at all the executable files in all the directories in the
environment variable PATH.
