NAME

       which - locate a program file including aliases and paths

SYNOPSIS

       [name...]

DESCRIPTION

       For  each  name given, 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  sourc-
       ing (executing) the user's file.

DIAGNOSTICS

       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

       The command:

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

       if the sh(1) being used is located in

WARNINGS

       reports aliases even when not invoked from csh.

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

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

AUTHOR

       was developed by the University of California, Berkeley.
