This can easily be done ... with the shell's integer arithmetic and due to the fact the GNU sleep adds all arguments to the final nanosleep(2) time: $ x=15500 $ sleep $((x/1000)) 0.$((x%1000)) I'm still not convinced - especially since the suggested suffix "ms" is a 2-character suffix and therefore would change the 1-character rule of suffix. I'm not sure if this could be a problem somewhere, though. If we want to support a suffix meaning a sub-second multiplier, then - as the underlying system call is nanosleep(2) - I'd rather go for using the single-char 'n' as suffix for nanoseconds. Have a nice day, Berny
