<nitpick> [ may be a built in but then again (as its presence in /usr/bin implies) it may not be :).
Like any other command.
But unlike '[[' which is the point I was replying to. Afaik you can't provide a '[[' binary and have it mimic the builtin exactly.
Because [[ is not a command, it is a reserved word, part of the shell grammar. That is the key difference, not the built-in property.
