Hi ppl,

I wanna know how to catch the signal <DELETE> in the command prompt? Also, <Ctrl-S> is a special character to suspend the terminal, so how can I catch this character? Should I simply monitor the stdin(fd=0)? And stdin by default is line-buffered, so how do I handle the command promt like an editor (display any character typed and read the line after <EOL>) and also handle other signals (e.g. send SIGINT to the own process when <ctrl-c> is pressed) ?

Thanz!! :D

I read something about this when reading a book on Bourne shell programming. You can catch those signals there (^Z for example, to prevent accidential logoffs).

What scripting language are you using? I'm guessing Perl... but, I have no way to know for sure.
