WHICH(1) BSD General Commands Manual WHICH(1)
NAME
which -- locate a program file in the user's path
SYNOPSIS
which [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
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.
FILES
~/.cshrc source of aliases and path values
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.
BUGS
Must be executed by a csh(1), or some other shell which knows about aliases.
HISTORY
The which command appeared in 3.0BSD.
