Synopsis
which file
The which
command locates
an executable file in your shell’s search path. If you’ve been
invoking a program by typing its name:
$ who
the which
command tells you
where this command is located:
$ which who /usr/bin/who
You can even find the which
program itself:
$ which which /usr/bin/which
If several programs in your search path have the same name
(for example, /usr/bin/who and
/usr/local/bin/who), which
reports only the first.
