which \- locate a program file including aliases and paths (\fIcsh\fR only)
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.
~/\&.cshrc source of aliases and path values
A diagnostic is given for names which are aliased to more than a single
or if an executable file with the argument name was not found in the path.
Only aliases and paths from ~/\&.cshrc are used, importing from the current
environment is not attempted.
Must be executed by a csh, since only csh's know about aliases.
