which(1)						      General Commands Manual							  which(1)

Name
       which - locate program file

Syntax
       which [name...]

Description
       The command 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.

Restrictions
       Must be executed by a csh, since only csh's know about aliases.

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

Files
       ~/.cshrc  source of aliases and path values

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.
