 NAME    [Toc]    [Back]
      which - locate a program file including aliases and paths

 SYNOPSIS    [Toc]    [Back]
      which [name ...]

 DESCRIPTION    [Toc]    [Back]
      For each name given, which searches for the file that would be
      executed if name were given as a command, and displays the absolute
      path of that file.  Each argument is expanded if it is aliased, and
      searched for along the user's path.  Both aliases and path are
      determined by sourcing (executing) the user's .cshrc file.

 DIAGNOSTICS    [Toc]    [Back]
      A diagnostic is given for names that are aliased to more than a single
      word, or if an executable file with the argument name was not found in
      the path.

 EXAMPLES    [Toc]    [Back]
      The command:

           which sh

      specifies where the executable program of the sh(1) command is found.
      For example, the response might be:

           /usr/bin/sh

      if the sh(1) being used is located in /usr/bin.

 WARNINGS    [Toc]    [Back]
      which reports .cshrc aliases even when not invoked from csh.

      which cannot find csh built-in commands (e.g. jobs).

      which's information may be incorrect because it is unaware of any path
      or alias changes that have occurred in the current shell session.

 AUTHOR    [Toc]    [Back]
