Hello all. I have a python script here which is just a wrapper for 2 or more system commands. I would estimate the program spends at least 95.5% of 'real' time running the system commands.
I want to trap the [crtl-c] key combo and exit (somewhat) gracefully if the user decides to abort the program. I am using os.system for the system call, and I have wrapped the entire main loop in a try: except KeyboardInterrupt statement to try to attain these ends. As it is though, if the program is currently in the system command, only that system command is terminated, and the next loop of my program starts. Is there a way to make this work? ie: terminate the entire script? Will popen do this? I don't really want to use popen because all I need is for the system command to run, and check the exit status. Also, popen will pooch the output of the system commands (which I want to be printed to the console) because the system commands (faad, mpg123, and oggenc) have buffered output which won't properly be displayed if I simply print each line of the file object returned by popen. I don't want to use subprocess because I can't expect my users to have 2.4 installed... OS is Linux, if it matters. If you need to see the code it is here: http://badcomputer.org/unix/dir2ogg/dir2ogg.bot Although, this code is the program as it stands, not the code I am testing.
