# NAME

`which` —
locate a program file in the users $PATH environment variable

# SYNOPSIS

`which` | [`-a`] name [...]

# DESCRIPTION

`which` takes a list of names and looks for the files which would be executed had these names been given as commands. Each argument is searched for along the user's `PATH`.

If the `-a` flag is given, `which` will continue to search the `PATH` until all instances of a program file are found.

# HISTORY

The `which` command appeared in 3.0BSD.

# BUGS

This implementation does not expand csh(1) aliases, and is shell agnostic. This is really a feature.
