Re: A nice-like command for making processes sleep from time to time

Hi, is there some way of launching a command from the shell in such a
way that the process will sleep x seconds every n seconds ? Of course I
am asking wether you can do it from "outside" (not by including it in
your own shell script for instance) a little like with the "nice"
command?

Regards,

If you don't want to use the real supercontroller (with 'nice')
you'll then have to mimic the interrupt/semaphore mechanisms.
Simplest way will be to include in your scripts some access to a
resource you'll control from outside the script, like loop and
wait/(test&set) for the presence of a file/fifo.

If your question concerns scripts to which you don't have
write access on machines to which you don't have 'nice' rights,
hey, wait a minute, freeze! ;D)
