I pipe the output to a program that keeps the last 25 lines in a file.

I wouldn't recommend the "> /dev/null" command. If you start it remotely, the stdout and stderr usually (but not always) go to e-mail.

On the other hand, if you do not have root access or do not want to fool around with init files (always dangerous), you can start mprime via cron as a normal user: this is what I do and here is my script file which is called every hour via cron. See the crontab command. #!/bin/tcsh set mersenne=`ps aux | grep -v grep | grep nicolau | grep mprime | wc -l` if ( $mersenne == 0 ) then echo "No mprime program running! Program will be initialized..." pushd ~/mprime >& /dev/null nice +19 ./mprime >& /dev/null & popd >& /dev/null else if ( $mersenne > 5 ) then echo $mersenne "mprime programs running!" endif endif The variable "mersenne" counts the number of processes called mprime run by nicolau; make sure your script is *not* called mprime_init or it will count the script itself! You must of course substitute your login where "nicolau" is. You may also want to add parameters to mprime, or change the path where mprime is located, or change the level of niceness. http://www.mat.puc-rio.br/~nicolau Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm

You might also want to look at the nohup and nice commands, depending on what exactly you are trying to do. If you've got root access (and the permission on the box's owner) you can also set mprime up to start when the system boots by modifying the init files in /etc/rc.d. -- Kevin Jaget (or an FDA approved generic equivalent) kcjaget at mindspring.com Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm

Mersenne: Prime95 on linux, a tech question
I'm trying to run mprime on a (test)webserver (linux/apache) with no console access. Now I can start mprime remotely through telnet - which works fine. But as soon as I quit the particular telnet-session - mprime quits too. Anybody can give me a hint how do keep mprime running? thanks in advance Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm
