WHICH(1)

NAME
which - report full paths of commands

SYNOPSIS
    which [-a] filename ...

DESCRIPTION
which prints the full paths to the commands given as arguments, depending on the $PATH environment variable. Nothing is printed if the command is not found.

  OPTIONS
which accepts the following options:

-a  Print out all instances of command on $PATH not just the first.

--  Stop parsing for options. Use which -- -- to find the path to --.

ENVIRONMENT
The environment variable $PATH (also DCL$PATH under DCL; or $Commands under MPW) is used to find the list of directories to check for commands. The variable %PATHEXT% is examined for command extensions if it exists.

BUGS
which has no known bugs.

COMPATABILITY
Traditionally, which also parses ones ~/.cshrc file to look for aliases, and reporting the alias when applicable. This version of which does not do that, because there are more shells than csh.

which will examine aliases under MPW (Mac) and symbols under DCL (VMS).
