WHICH(1)                    General Commands Manual                   WHICH(1)

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

     which [-a] name [...]

     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.

     The which command appeared in 3.0BSD.

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