Controlling program execution...

echobase · 08-10-2009, 03:11 PM

Hi-

I need to be able to run a program from the command line and then have it terminate only when I type in a special code of my choosing. I would want to deactivate the usual CTRL-C method of termination. Is this possible?

I guess, if your keyboard will be on other then english lang set, CTRL+C won't work

Try the 'trap' cmd in bash

to begin with, deactivating crtl-c should be as easy as this:

Code:

trap : SIGINT

Well I'm sure that works in shell script mode but not sure in direct interactive mode.
The other one will be a lot more difficult though. Perhaps in bash, you can do that by modifying readline settings. I never have done that before though. Do 'man bash'.
