I am trying to figure out how to call oascript using do shell script from an AppleScript, and am having some problems.
So for testing, I am using this simple script (which works fine in the AppleScript editor):
--Simple AppleScript
tell application "System Events" to count (every application process whose visible = true)
Now when I try this, it does NOT work (generates syntax error)m, and I cannot figure out how to make it work… probably has something to do with nested quatation marks, but have tried many variations and cannot figure it out:
--This does NOT work
do shell script "/usr/bin/osascript -e \"tell application \"System Events\" to count (every application process whose visible = true)\""
However, I did come across this method which does work:
--This does work
do shell script "/usr/bin/osascript <<EOF
tell application \"System Events\" to count (every application process whose visible = true)
EOF"
Now, if you want to fork something off to osascript and have the applescript continue without waiting for osascript to finish, you can theoretically use “&> /dev/null &” to send it to null and have it return to applescript right away.
So on the command line it would look like
osascript -e "some commnad" &> /dev/null &
The problem is, that I cannot get “&> /dev/null &” to work with the EOF method, and since the first (non EOF) method does not work at all, I cannot even test this on it.
So any ideas on why the non-EOF do shell script does not work?
And any ideas on how to get “&> /dev/null &” to work?
Thanks
