Thank you very much for your reply . Can you please do me favor and let me know where I have to check for the scripts that may wipe out these files on reboot ? How can I check if /var/spool on transient storage ? Please be informed that I have two CentOS servers , one is running CentOS 5.0 and the other is CentOS5.2 . For the CentOS5.2 , the cron job does not disappear after server reboot but for the 5.0 one it does . Can you please let me know what is wrong here ?
this would be something specific you've done intentionally... its certianly not something that happens by default in any normal installation
I'd agree with John that this isn't normal UNIX/Linux behavior, that something somewhere has been added to the system code to cancel the change you make to crontab.
As a kludge, you could add your "crontab /tmp/temp" to the end of /etc/rc.local so that it is invoked again after the reboot.
Do a "crontab -l" periodically throughout the day to see if there's a particular time when your reboot command disappears from it.
