the problem I end up with is that if I use a *.rrd, the source directory becomes part of the $FILE.
Code:
/backup/cacti_xml.sh: line 9: /backpu/cacti_xml//var/www/html/rra/rg100_traffic_in_1108.rrd.xml: No such file or directory
That is why I was thinking of cleaning up the whole 'cd' to directory, and then do stuff. I don't think it's necessary, and I don't know how to strip the /var/www/html/rra out of the $FILE variable so that when it writes the xml to /backup/cacti_xml, it won't include all of this information.
In that case do this.
Code:
for FILE in `cd sourceDir ; ls -1 *.rrd`
do
rrdtool dump "$FILE" > "/path/to/$FILE.xml"
done

Thanks for the all the help last evening on CRON jobs. It's now working.
Is it possible with cron to save a backup of a file to a different server or location? The idea being that if one host goes arse over tit, I'll have a backup of the DB on another server?
Many thanks,

cron
CRON(8) System Manager's Manual CRON(8)NAME
cron - clock daemon
SYNOPSIS
auth/cron [-c]
DESCRIPTION
Cron executes commands at specified dates and times according to instructions in the files /cron/user/cron. It runs only on an authentica-
tion server. Option -c causes cron to create /cron/user and /cron/user/cron for the current user; it can be run from any Plan 9 machine.
Blank lines and lines beginning with # in these files are ignored. Entries are lines with fields
minute hour day month weekday host command
Command is a string, which may contain spaces, that is passed to an rc(1) running on host for execution. The first five fields are integer
patterns for
minute 0-59
hour 0-23
day of month 1-31
month of year 1-12
day of week 0-6; 0=Sunday
The syntax for these patterns is
time : '*'
| range
range : number
| number '-' number
| range ',' range
Each number must be in the appropriate range. Hyphens specify inclusive ranges of valid times; commas specify lists of valid time ranges.
To run the job, cron calls host and authenticates remote execution, equivalent to running rx host command (see con(1)). The user's profile
is run with $service set to rx.
Cron is not a reliable service. It skips commands if it cannot reach host within two minutes, or if the cron daemon is not running at the
appropriate time.
EXAMPLES
Here is the job that mails system news.
% cat /cron/upas/cron
# send system news
15 8-17, 21 *** helix /mail/lib/mailnews
