Don't you have to have the user in here?
Not unless you're /etc/crontab. See 'man 5 crontab':
The format of a cron command is very much the V7 standard, with
a number of upward-compatible extensions. Each line has five
time and date fields, followed by a command, followed by a new-
line character ('0). The system crontab (/etc/crontab) uses
the same format, except that the username for the command is
specified after the time and date fields and before the com-
mand.

In linux.debian.user, you wrote: I use crontab -e to edit my personal crontab. The format that you are looking for is: * * * * * command \n The first star is the minutes: every 5 minutes would be 0-59/5 or 0,5,10,15,20,25,30,35,40,45,50,55 The second star is the hours: every hour is * The third star is day of the month The fourth star is month of the year The fifth star is day of the week: Sunday is both 0 and 7. The \n means that every line must end with a new line. So every five minutes is something like: 0-55/5 * * * * command \n I have put this in using crontab -e so that all the info is there when I do my next edit: #minute (0-59) #| hour (0-23) #| | day of the month (1-31) #| | | month of the year (1-12) #| | | | day of the week (0-6 with 0=Sunday) #| | | | | commands It is at the top and then my cron jobs are lined up under it. -- Anita GnuPG key: 1024D/9EDAC910 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Joyce, Matthew [EMAIL PROTECTED] [2002-11-11 10:47:51 +1100]: I have put this in using crontab -e so that all the info is there when I do my next edit: #minute (0-59) #|hour (0-23) #|| day of the month (1-31) #|| | month of the year (1-12) #|| | | day of the week (0-6 with 0=Sunday) It is at the top and then my cron jobs are lined up under it. I've long done similarly. Good practice. Me too. Isn't there a 'user' option before the 'command' ? In system level /etc/crontab and /etc/cron.d/* files yes, but not in user level 'crontab -e' files no. If you got to it with 'crontab -e' as above then no. The user is you. Only the root user on the machine has the option to run a crontab as another user. And for that you have to edit files elsewhere. Bob msg12229/pgp0.pgp Description: PGP signature
