# 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.
