Page 170 of the Casper Suite 6.0 Documentation.pdf talks about scripts
briefly, and refers you to the example scripts. The example scripts
that come with Casper (they would've been in the original installation
DMG) show that $3 is the current user (although it is only populated
if the script is called at login or logoff.)
The 'w' and 'who' commands will give the users who are currently
logged in. I think
who | grep console | cut -d " " -f 1
will probably be the best way to get a list of all users logged in
graphically.
As for getting a list of all users who have accounts on the machine,
if they are all in the Users folder, you could do something like this:
for USER in `ls /Users` ; do echo $USER ; done
If your users aren't all in the Users folder, you probably have to
move on to using dscl, and it'll take a bit more effort.
Lastly, Casper has facilities to "Fill User Templates" (FUT) and "Fill
Existing Users" (FEU), which helps if you need to create or modify a
file for all users. Or, to really make use of the $3 parameter, you
should create a script that runs at login, scheduled to run once for
each user.
I hope this answers your question.
Cheers,
Clinton
