> Could check for e.g., sleep 4 5 This is a well-defined extension of GNU sleep; it is equivalent to sleep 9. GNU adds its arguments, so that you can do, for example, 'sleep 1m 30s' to sleep for 90 seconds.
However, it does raise the point that sleep does not like negative numbers, even though it might be useful: 'sleep 1m -1s' could sleep 59 seconds rather than giving an error. -- Eric Blake _______________________________________________ Bug-coreutils mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-coreutils
