I run a private centos mirror. Using rsync from the es.net mirror I'm sure you get this all the time, but how do I use lock files with the rsync client to keep multiple from spawning because of cron jobs? My mirror also hosts ubuntu and a few others which run at the same time, if this info is needed. Right now the cron job just SH's a script containing a screen call with the rsync command in it. And I would like to keep it this way. At least that sh script. What im really looking for is a script that checks for the lockfile if its running. And then if its not SH's the script. I would have the cron job run that script, and that script would run my sh script called centos.sh located in /root/ Server is run on centos 5.3 i386 Let me know any other info needed -------------- next part -------------- An HTML attachment was scrubbed...
