I'm using FC 14, but this is probably a fairly generic Linux question.
I want to be able to bind a key in the Linux terminal driver that will cause a signal other than
SIGQUIT to be raised for the running application. I don't want to co-opt either of those. If it rings a bell for you, think along the lines of the old
CTRL/T capability, only with the signal being caught and handled by the app rather than the OS.
Since this is for status reporting for long-running activities,
SIGUSR1 seems appropriate. However, if specifically raising that from the terminal keyboard isn't an option, I'll take what I can get. I don't want to attempt the impossible and catch
SIGKILL B-) but I would like to be able to raise signals other than
SIGINT from the terminal keyboard.
- Set up the terminal to do the signal-raising thing
- Run application from shell in terminal window
- Wait until it gets into the complex long-running section
CTRL/whatzitto raise the signal
- Application catches the signal, does some sort of status report, and resumes
I could do this with no problems on VMS/OpenVMS, and it kinda frosts my pumpkins to think it's more difficult on Linux.
