Hi
Not 100% sure (has to be validated) tcl isn't supported on asa.
The best way to handle that is running a perl or python script that'll connect on all your boxes and get these informations for you.
With which tool are you more comfortable.
Behind the scene, you'll need to paste the acl output to get the line you requested through a variable.
Thanks
Francesco
