Not sure if I am using the correct terminology:
I have a user setup in a menu. I want to let the user browse a file using the pg.
I want to prevent the person from doing <ctrl>c and being able to exit the script to the command line.
How do I do this?
man trap.
you can also do a search on this site for that command.
Interesting. No man pages on trap on my servers.
syntax
trap "command to run when signal trapped" "list of signals"
trap "" signals # Will trap the signals you define but not allow them to affect your script.
you can get a list of signals by typing kill -l on the command line. Note: You cannot trap signal 9. Your "command to run" can be a function if you so choose.
The syntax depends on your shell. If you are using ksh, you would do a "man ksh".
the man page gives examples for various shells.

Yeah, but only Sun has that trap man page. At least it's not on HP. On linux I get a bash man page with "man trap".
