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 com-
     mands.  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.
