Default [SOLVED] Cronjob script does not run in cron

Hello mateys!

I have a /root/backups.sh script which should be run by a cronjob. What it does is tar many directories, encrypt them with GnuPG and then move the gpg file to a usb stick that was mounted by that very same script.

It works flawlessly if I run the script manually from root. However, it does not seem to be run when I put it in a cronjob although I have an entry in /var/log/cron saying it was run. Also, I don't have any entry in /var/log/messages about the mounting of the usb stick.

I put some debug lines (as in echo "start" > /root/backups.log) and they do not even get executed!

Is there something I should know?


Thanks folks and thank you for building a new and better forum! ;-)

It could be helpful to post your script here

Be sure to sanitize anything that you might not want to be public (passwords, etc) but try not to remove too much of the script so that we might be able to hunt down the problem for you.

mount -t msdosfs /dev/da0s1 /mnt/usb-storage

echo "AFTER MOUNT" >> /root/backups.log

# Leave now if we're not on the backups usb stick
if [ ! -e /mnt/usb-storage/dummyfile ];
then
	echp "Error. Wrong USB stick plugged in." >> /root/backups.log
	echo "Error. Wrong USB stick plugged in."
	umount /mnt/usb-storage
	exit 1
fi

rm -f /mnt/usb-storage/*.gpg

echo "AFTER REMOVING ALL GPG FILES ON USB STORAGE" >> /root/backups.log

# Current date; used for filename
FILENAME=/home/frank/`date +'%Y-%m-%d'`-frank.tar.gz
FILENAMEGPG=$FILENAME.gpg

echo "FILENAME = $FILENAME" >> /root/backups.log
echo "FILENAMEGPG = $FILENAMEGPG" >> /root/backups.log

echo "BEFORE TAR" >> /root/backups.log

tar -cvzpf $FILENAME /home/frank/.mozilla/firefox/

echo "AFTER TAR" >> /root/backups.log

gpg -e -r email@domain.com $FILENAME

echo "AFTER GPG" >> /root/backups.log

rm -f $FILENAME

echo "REMOVED TAR FILE" >> /root/backups.log

Rem: cron runs effectively on a 24/7 machine.
If you reboot frequently you should install sysutils/anacron

The only thing you should know is that the PATH in a CRON environment is very limited compared to the PATH in the cron environment.

You either explicitly set and export the value of PATH in your cron script, or use fully qualified names for the utilities you use. For example: /bin/tar instead of tar.

Hello folks,
thanks for the answers.

My machine is always up. For my tests, I created cron jobs one minute after the current time and the job was executed every time according to /var/log/cron.

I have modified the first echo so it now looks like this: /bin/echo "START" > /root/backups.log

However, after the job was ran (according to /var/log/cron), the /root/backups.log does not contain that entry. It really looks like the script was not executed at all.

I really don't understand what's happening

Hmm... what does your crontab entry look like? Also, this may seem silly, but... is the "x" set for execute? "-rwxr-xr-x" for example?

Hello,
my crontab entry (for tests) looks like this:
43 17 * * * root /root/backups.sh

At first I tried without setting the username under which it should be run.

Yep, the permissions are set to a+rx.

Are you aware of http://www.freebsd.org/doc/en_US.ISO...ning-cron.html, which explains that FreeBSD has two different crontabs? The first is the system or root's crontabs, the second are the user crontabs. They have a slightly different format

I guess it was a case of RTFM!

I also added the PATH in my crontab and added /usr/local/bin to the PATH given in the handbook in order to resolve GnuPG correctly.

Thank you!
