Name
       which - locate program file

Syntax
       which [name...]

Description
       The command 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.

Restrictions
       Must be executed by a csh, since only csh's know about aliases.

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.

Files
       ~/.cshrc  source of aliases and path values
