He may also be running "cd /usr" from inside a script and expecting his
working directory to be "/usr" after the script exits. That won't work
either, because scripts are executed in a forked shell. If this is
what he wants to accomplish, then he must source the script instead of
running it.

In addition "builtin" is not the name of a command, so naturally Bash
will complain about that.

home> echo $SHELL
/bin/bash
home> type builtin
builtin is a shell builtin

Actually, it is. It is a builtin command. Which makes me suspect
strongly that he is not running the script under bash. Maybe sh,
although builtin is also a builtin under sh.
