NAME
     which -- locate a program file in the users $PATH environment variable

SYNOPSIS
     which [-a] name [...]

DESCRIPTION
     which takes a list of names and looks for the files which would be executed had these names been given as commands.  Each argument is
     searched for along the user's PATH.

     If the -a flag is given, which will continue to search the PATH until all instances of a program file are found.

HISTORY
     The which command appeared in 3.0BSD.

BUGS
     This implementation does not expand csh(1) aliases, and is shell agnostic.  This is really a feature.
