very possible, as nicole and tim pointed out with nohup and background operator. however, if your simulations are like mine, they spit out useful information every once in a while like whether the simulation has lost too much precision or how near it is to completion. screen might be a better choice if this is the case. simply instructions: 1. log into the machine that will run the simulation. 2. run screen. 3. start your simulation. 4. type ^d to detach your screen session. 5. log out. whenever you want to check up on your simulation, you can: 1. ssh back into the machine 2. run screen 3. your session will be restored 4. type ^d to detach it again if your simulation isn't done. for completeness, i used to use cron and atd for this same purpose. atd worked well. but screen is a much better solution. i was a newbie back then. :) also, i've found this helpful: ./mysimulation ; mail -s "i'm done" [EMAIL PROTECTED] so you know when the thing is done and don't have to keep checking back every few hours. hth, pete -- GPG Instructions: http://www.dirac.org/linux/gpg GPG Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D _______________________________________________ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
