POSIX requires these shell builtins to also exist as totally pointless external commands. Since they serve no useful purpose, it's OK that their implementation is not the most efficient possible. 2002-07-16 17:13:11 -04:00			`#!/bin/sh`

Use the "builtin" shell function to make sure that the requested command is handled as a shell function. This avoids the following peculiar behaviour when /usr/bin is on a case-insensitive filesystem: # READ foo (... long pause, depending upon the amount of swap space available ...) sh: Resource temporarily unavailable.
