Thread count of process x

applescriptunix

My AppleScript needs to get thread count of process x.

I have tried many ps etc codes but all these are not working for some reason.

I tried these:

do shell script "ps uH p 301 | wc -l" -->"       0"
do shell script "ps axo pid,ppid,rss,vsz,nlwp,cmd" --> error "ps: nlwp: keyword not found

ps on OS X takes different options than ps on Linux. Please have a look at man ps to see the detailed list of supported keywords. For threads I found the following (but I don't know whether this is the information you are looking for):

 wq         total number of workqueue threads
 wqb        number of blocked workqueue threads
 wqr        number of running workqueue threads

PS: I would recommend to first test any unix level commands in Terminal/bash and only move to AppleScript once they are working as expected. You are far more flexible in bash and also may get better/more helpful error messages back.

AppleScript “Kill” Command Error

You can do what you are trying to do using the killall command and referring directly to the application's name.

repeat
 delay 84600
 set app_name to "APPLICATION NAME"
 do shell script "killall " & app_name
 delay 30
 tell application app_name to activate
end repeat

Applescript – ignore modifier keys

Well, hard to prove a negative but, as the question you linked to yourself says: you are holding the ⌘ and ⇧ keys down when calling the script. It can not ignore them. Apple script is scripting, and much closer to GUI scripting than to applicative scripting.

I cannot offer any other idea than in the answer to the question you sent: just add a slight delay so that you release the keys before the keystrokes are sent.

delay 0.2
