NAME
     which - locate a program file including aliases and paths (csh(1))  only)

SYNOPSIS
     which [name] ...

DESCRIPTION
     Which takes a list of names and looks for the files which would be exe-
     cuted 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
