which(1)                (BSD Compatibility Package)                which(1)

NAME
     which - locate a command; display its pathname or alias

SYNOPSIS
     /usr/ucb/which [filename] ...

DESCRIPTION
     which 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.

DIAGNOSTICS
     A diagnostic is given for names which are aliased to more than a sin-
     gle word, or if an executable file with the argument name was not
     found in the path.

NOTES
     Only aliases and paths from ~/.cshrc are used; importing from the
     current environment is not attempted.

     which must be executed by csh(1), since only csh knows about aliases.
     If you are using sh instead of csh, whence -v provides similar func-
     tionality.

     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
     produce some strange results.

FILES
     ~/.cshrc
          Source of aliases and path values
