WHICH(1)						    BSD General Commands Manual 						  WHICH(1)

NAME
which -- locate a program file in the user's path SYNOPSIS
which [-as] program ... DESCRIPTION
The which utility takes a list of command names and searches the path for each executable file that would be run had these commands actually been invoked. The following options are available: -a List all instances of executables found (instead of just the first one of each). -s No output, just return 0 if all of the executables are found, or 1 if some were not found. Some shells may provide a builtin which command which is similar or identical to this utility. Consult the builtin(1) manual page. SEE ALSO
builtin(1), csh(1), find(1), locate(1), whereis(1) HISTORY
The which command first appeared in FreeBSD 2.1. AUTHORS
The which utility was originally written in Perl and was contributed by Wolfram Schneider <wosch@FreeBSD.org>. The current version of which was rewritten in C by Daniel Papasian <dpapasia@andrew.cmu.edu>. BSD
