Why aren't you just installing the launchd agent
in /Library/
...
LaunchAgents ?
...
This way you don't have to know or care who is currently logged in,
...
and it will work for all users (current and future) of the machine.
XO: I do install the plist in /Library/LaunchAgents.
 The reason that I care is that if either of our programs is running
when the installer runs, I have to stop the program before installing again.
 This doesn't work nicely if other users are logged in because I can't
stop the agent for them also.
...
sudo shouldn't give you a second user via a "who"
command.  But a
...
Terminal window (or multiple terminal windows) will:
...
XO: It doesn't give me an extra user.  What happens
is that when the Installer GUI is used to install the package, the $USER
environment variable is set as my user, 'xlunde'.  If I use 'sudo'
to run the installer on the command line, the $USER parameter is set to
'root' instead.  Because my script checks for users logged in who
are not $USER, I get the error.
My post install scripts also try to start the launch
agent for the $USER, so this might work weird or not at all if 'root' is
the $USER.
...
When you run it from a command line what your
script is seeing is the
...
console session and the tty session.  When run via ARD, if no
users
...
are logged in, that script should run fine (but I still suggest
...
testing it).
XO: I don't have ARD that I know of, and it doesn't
look like it's free. This software is going to an external testing house
later, so they'll have to test that. : /
...

...
Short of building an array based on the awk $1 of the who command,
my
...
only other suggest would be to grep for "console" between
your who and
...
your awk, ie:
...

...
who | grep console | awk ' { print $1 } '.

xlunde is logged in!

Obviously, I did this to myself.

for name in `who | awk {'print $1'}`

do

if [ ! $name = $USER ] ; then

echo "${name} is logged in!"

exit 112;

done
