$ ./waitexit -h
Prints a countdown in terminal while waiting to exit. When timer reaches zero or
any input occurs, the program exits.
Use: waitexit [opts] N, where N is number of seconds to wait.
Options:
-m MSG Use a custom countdown message template, where '%S' is replaced by
number of seconds left.
-e CODE Exit with status CODE.
-f Exit with status 0 if user presses a key within the timeout, otherwise
exit with non-zero code.
-z Suppress printing of wait time and status code on exit.
-s Be completely silent, do not output anything while waiting or on exit.
-h Show this help.
May be a useful command for scripts which run in pop-up terminal windows, and for which you would like to keep the terminal open for some amount of time at exit, before automatically closing the window.
Other than that, maybe as an example of how to write a "press any key" CLI event
handler in C or using the getopt argument parser.
