Hi guys i'm wondering if any one can point me in the right direction I have a particular pkg file that i'm attempting to see the commands its running as well as the order they are running in, I've attempted to tear apart the file and hit a wall when i notice most of these files are pre -encrypted. what im wondering is there any way to view the commands while the pkg is being run aside from ps -e . any help would be appreciated.
