NAME
     which -- locate a program file in the user's path

SYNOPSIS
     which [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
     expanded if it is aliased, and searched for along the user's path.  Both aliases and path are taken from the user's .cshrc file.

FILES
     ~/.cshrc  source of aliases and path values

DIAGNOSTICS
     A diagnostic is given for names which are aliased to more than a single word, or if an executable file with the argument name was not found
     in the path.

BUGS
     Must be executed by a csh(1), or some other shell which knows about aliases.

HISTORY
     The which command appeared in 3.0BSD.
