I have a shell script currently that cron runs as a user called nbsnet which starts up a monitoring program and is left to run throughout the day. At the end of the day, this user's cron will kill the process and do some work with the data it received. I take the machine down once a month for backups, etc but this process is never restarted ( I have reset it in cron now) What I would like to do is have the rc.local run this script and start up this monitoring program as a part of its startup but I want it to start the process so the user is nbsnet not root. Is there a way to do this and if so, how? Your assistance is appreciated. Without the net, my job would be twice as hard. coleman@bldrdoc.gov Sean Coleman NIST Boulder, CO

Is there a way to do this and if so, how? Use: su -c user "command string" My (AT&T sysV) man page gives very little information about this form but as I recall, it runs the users shell as per the passwd file as well as using the uid, and if that shell is ksh, it will execute the user's .profile, where sh will not (watch out for interactive commands!). I prefer to let init respawn this kind of program, since it can then exit under whatever conditions you want and a new copy will always restart, and a screw-up like an interactive prompt won't hang the machine like it does in the rc.d files. You probably only want it at run-level 2 and 3 anyway. Les Mikesell les@chinet.chi.il.us
