which - locate a command; display its pathname or alias
which [ filename ] ...
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.
~/.cshrc source of aliases and path values
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
Only aliases and paths from ~/.cshrc are used; importing from the cur-
rent environment is not attempted. Must be executed by csh(1), since
only csh knows about aliases.
To compensate for ~/.cshrc files in which aliases depend upon the
prompt variable being set, which sets this variable. If the ~/.cshrc
produces output or prompts for input when prompt is set, which may pro-
duce some strange results.
