Try 'man 5 crontab' - there's an @reboot string that can be used instead of the normal time specification in a crontab file to have the command run once at startup (of the cron daemon, presumably). > is there a way to do it with cron ? or otherwise is there another way ? > > I guess there might be a way to put a script in /etc/rd.d/ but I > don't know how to run it under a specifid uid Your rc.d script could just use 'su' to switch to the desired user and execute another script as that user: su - someuser -c /path/to/some/script su passes everything after the username as arguments to the shell running as someuser. I guess the advantage of running your script out of /etc/rc.d is that you can control when it gets run relative to all the other startup scripts - 'man rcorder' for details on this.
