If you are using the System V shell (or SunOS /bin/sh these days), you
could also define a shell function:
	start(){
	    date
	    who
	    cd /users
	}
Put this -- and any others you invent -- in a standard place, such as
/usr/local/lib/sh-functions,
make it executable with chmod +x, and add
	if [ -x /usr/local/lib/sh-functions ]
	then
	    . /usr/local/lib/sh-functions
	fi
into either /etc/profile (at the end) or the users' own .profiles.

Then they don't need to type the dot.

This question seems to come up a lot, but this particular (somewhat
pragmatic) solution seems not to be suggested often, so I have posted it here.
