.SH Description
.NXR "which command (csh)"
.NXR "file" "finding executable"
The
.PN which
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.
.SH Restrictions
Must be executed by a csh, since only csh's know about aliases.
.SH 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.
.SH Files
.ta 1i
~/\&.cshrc	source of aliases and path values
