- I need to have a shell script that sits and waits for a signal and then
- performs some action, e.g.:
-
- trap "command" signum
-
- while :
- do
- sleep 60
- done
-
- (I think).
-
- It appears, though, that certain signals are recognized, but some (like
- USR1 and USR2) never get caught. Any clues?
-
- I notice that signal 20 (SIGPOLL) seems to work OK. What other programs/drivers
- might send SIGPOLL in a strictly character-based, ASCII terminal type
- of environment?
-
- Is any of this different under SCO UNIX?
