Yes. To schedule a one-time job you should use 'at' instead. >Also, what do i do if i want the info to be sent to someone other that >root when the virus scan and back up run?

It would probably be best to put all the required commands into a script and just call the script using cron. Such a script might look like this: #!/bin/sh # # Scan files for viruses and email a notice of the results. # Who gets notified. [EMAIL PROTECTED] msgsubj='Antivirus Scan Results' # Set the list of directories to scan dirlist='/www/servers/skylight.ubc.ca/media/ /www/servers/skylight.ubc.ca/profsTalk' # Send scan output to this file. reportfile=`date +%Y-%m-%d.txt` # Run the scan and send the result notice. if sun sweep $dirlist > $reportfile; then msgbody="Scan completed successfully. See $reportfile" else msgbody="Scan failed. See $reportfile" fi echo "$msgbody" | mail -s "$msgsubj" $recipient # End of script >Second, the cron tab will run the backup.sh script file.

Actually, you should avoid using bash and use sh instead. Your scripts will be more portable: #!/bin/sh >$currDate = getDate; When setting a variable, do not use '$'. That symbol is used to retrieve a variable value. You're trying to set the variable, not retrieve its value. Do not put whitespace around the equals (=) sign when setting a variable. Bash respects end-of-line. You do not have to end your lines with a semi-colon. Perl/C habits die hard, huh? ;-) The command would look like this: currDate=`date +%Y-%m-%d` Today, the $currDate variable would contain "2002-08-20", which is a good format for sorting. >mkdir /data/backups/$currDate > ># Backup the web server files >tar cfv www.tar /data/www >gzip www.tar You can tar and gzip in one step: tar -czvf www.tar.gz /data/www [snip] >Also, I think i have to be root to run the above commands, should this be a >problem, or does the crontab run the backup.sh script as root? In /etc/crontab, you can specify the user that the command should run as. Specifying root is no problem, if that is necessary for the command to function properly. Tony - -- Anthony E.
