SUMMARY: cron problem

Cron prob has been resolved.

The manpage from crontab seems to indicate that the fields are an OR not
an AND.

eg

> 0      2       1-24    *       0
> /usr/openv/netbackup/ext/db_ext/sap/scripts/sap_offline_backup

Would run every day from the 1st to the 24th AND every Sunday.


But if you had the following:
> 0      2       *       *       0
> /usr/openv/netbackup/ext/db_ext/sap/scripts/sap_offline_backup

It would only run on Sundays.  If it followed the logic above it would
run on every days AND Sundays!

therefore the fields operate under the OR logic.   My thinking was that
if I restricted the dates then it would run between the 1-24 and only on
Sundays.
I guess not!


Thanks to all that replied.

Having a problem with cron on a Sol 9 (09/04) box.

Relevant root crontab entries:

#
# 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
#
# SAP BACKUPS
#-------------
#
0       23      *       *       1-5
/usr/openv/netbackup/ext/db_ext/sap/scripts/sap_online_backup
0      2       1-24    *       0
/usr/openv/netbackup/ext/db_ext/sap/scripts/sap_offline_backup
#
# Monthly Offsite Backups - Set date -  last Sat of every month.
0      2       25-31   *       0
/usr/openv/netbackup/ext/db_ext/sap/scripts/monthly_offline_backup

Problems:

1.  the sap_offline_backup script runs every night but is specified to
run on day 0 only.

2.  the monthly_offline_script ran last Sunday even though it was the
11th of the month.  It is specified to run on the 25th - 31st of each
month.
