What is your operating system ?? Your default shell ? csh ? bash ? sh ? ksh ??

Is ebarnes@jupiter - /etc> prompt oki for you ? Or you'll need the whole domain name ? Which is very hard to get depending on
the OS.

You could put the following in your .login file

set prompt="$USER\\!hostname` - `pwd`>"

That should do it.

ooppss typo...

set prompt="$USER\\!`hostname` - `pwd`>"

also note that those are back tics around hostname and pwd not single quotes.

This will only set the prompt correctly at login.  If the user changes directories then the prompt is no longer valid.  You would also have to alias the cd command to re-do the set each time it was executed.

bchew is right, csh has no possibility to do this itself, you also must alias the cd,  pushd commands.
In tcsh you may use:
set prompt="$USER\\!`hostname` - %C%"

(assuming that hostname returns the fqdn)
