Cronjob not being executed

Question

I'm trying to run rsync-books with a crontab. Typing crontab -e outputs:

55 12 * * * diegoaguilar /storage/bin/rsync-books

Where /storage/bin/rsync-books looks like this:

if [ -d "/media/Beagle/books" ]; then
  rsync -rP --delete --verbose /storage/Copy/Books/ /media/Beagle/books >> ~/rsync-books.log
fi

Just to confirm, this script has got executable permissions. I tried waiting at that time the command, when /media/Beagle/books existed and it neither rsync anyhing or the log file was created.

Is there something I'm missing?

Answer 1

Cron runs commands without an environment so there's no PATH variable set. Because of this you need to specify the full path to rsync in your script.

if [ -d "/media/Beagle/books" ]; then
  /usr/bin/rsync -rP --delete --verbose /storage/Copy/Books/ /media/Beagle/books >> ~/rsync-books.log
fi

Also, if you're running crontab -e don't include the username in the crontab entry. Your crontab should look like

55 12 * * * /storage/bin/rsync-books

EDIT: cron runs in a non-interactive shell so the environment (and PATH) may be different from what you expect. It's always best to specify full paths in any script that will be run from cron.
