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.
