that would be a "batch" system that runs forever. fortunately, he's going to sleep, so it doesn't eat CPU too much, but it *will* eat memory, and start and stop processes continuously (usually not a problem, but if the system is heavily loaded, this might overload it, particularly if many users will be running this batch system). crontab -e lets users schedule their own cron jobs without needing to be root. the thing lang about that is, the syntax still gets in the way of non-techies. there are lots of possible workarounds here, still, using cron or at. i've said before, that i've seen perl and bash jobs that run for too long and then start eating up the CPU for no reason. maybe the current kernels and perl and bash implementations won't do this anymore (this was a few years ago, and i've forgotten the details, except i moved that system to use cron instead because of the problem), but maybe they still do and he's going to find out the hard way. if you can do it right (with cron or at), then it's better to do it right. although, if he's just in the mood to hack, well, that's fine too as long as he knows the potential problems and accepts the responsibility if the thing blows up :). tiger -- Gerald Timothy Quimpo [EMAIL PROTECTED] [EMAIL PROTECTED] http://bopolissimus.sni.ph Public Key: "gpg --keyserver pgp.mit.edu --recv-keys 672F4C78" malapit na ang september "My name is Ozymandias, King of Kings: Look upon my works, ye Mighty, and despair!" -- Percy Bysshe Shelley, "Ozymandias" -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
