Disable keys?

[Chua Wen Ching]

If i want to disable ctrl + c, i will use:
trap '' 1 2 3 15

Can i use trap to disable enter key, backspace key, spacebar key, F1 key, etc? Is there other solutions than using trap.

I am using HP-UX 10.20. Can anyone show me an example in bourne shell script? Thank you.

You really can never disable a key on a keyboard unless you take a five pound sledge hammer to it.

You CAN though, ignore the key with your application. Most key strokes can be ignored via stty.

man stty

You mean i need to specify stty command in my application. What if i set the intr key in my application to "^H" but my .profile intr key is "^c". So when i execute it, which one come first? Thank you.

What you are asking is a more general question: how to process every keystroke, sort of like vi? The answer is that you can use stty to set the appropriate options and then have a very long shell script to handle each character based on the previous character(s).

NOTE: The trap command does not disable a specific character. Instead, the trap numbers refer to kill signals (use kill -l to see a list) and some of these kill signals are assigned by stty to special characters.
