I simply want to check and see if iTunes is running, if it is -- do nothing, if it isn't -- custom trigger to update it.



This seems to be working for everything I throw at it except iTunes. Looks like ps is picking up iTunesHelper even when iTunes is quit. Any suggestions here?



process="iTunes"

processrunning=$( ps axc | grep "${process}" )

if [ "$processrunning" != "" ]; then

    /bin/echo "$process IS running, we do nothing now"

else

    /bin/echo "$process IS NOT running - run custom trigger here to update"

fi

Adjust the line to look like this:



processrunning=$( ps axc | grep "${process}$" )

As suggested, putting a dollar at the end will help prevent false positives. You could be more specific with:



osascript -e 'tell app "System Events" to count processes whose name is "iTunes"'


Alternatively, you may wish to consider doing updates as part of a logout process instead.

@mm2270 - bingo, that'll do it thank you very much.



sean -in this case yes, logout would be better technically. And at login I'm finding iTunes frequently launching before the update runs to completion, causing problems. I have varying 'social' problems running updates at both login and logout.

Howdy, all! I have a custom script here that leverages this basic concept into a policy that can be used in Self Service. It effectively just checks to see if a specified process/application is running and then executes the installation if it is not running. If it is running, the user is prompted with a JAMF Helper window which times out after 30 seconds.



Parameters are fun :)
