They're not scripts. They are programs!

No process can change the working directory of another.

To make a shell change directories based on commands in a file, you
need to "source" the commands into that shell.

i.e.
	restore3:~ admin$ . ./somescript.sh

Note the leading dot, all by its lonesome. It's a shorthand for
"source". You can use either but there's less opportunity to
mis-type "."
