The files I enter there are actually in either ~/shell-scripts/ (for my crontabs) or in /root for root's crontabs. I suggest you use the same storage devices. These files are date-time specific; for example, in my crontab I have: # run postgres backup daily at 11:15 pm #15 23 * * mon-fri /home/rshepard/shell-scripts/postgres-daily-backup.sh # process spam-uncaught 10 2 * * sun /home/rshepard/shell-scripts/process-spam.sh Some of root's crontab files are: # dirvish backup each day at 00:30. 30 0 * * * /root/dirvish-backup.sh # copy bkup1 to bkup2 each day at 01:00 0 1 * * * /root/copy-backup.sh # postfix mail log report 45 3 * * * /usr/bin/pflogsumm.pl -d yesterday /var/log/maillog.1 HTH, Rich

Names of what? I still haven't found where cron is storing the jobs. The cron man page is silent on the subject, and online I haven't found it mentioned yet. It's not /var/spool/cron; empty on both systems. And it's not in /etc/cron.d or any of the /etc/cron. folders, because all they have is the standard default folders and files, all with old timestamps. Several GUI cron alternatives are mentioned on the net, but none seem to be in the Debian or Xubuntu repositories. I also haven't found a cron tutorial that is useful. I don't need instructions, I just need several pages of examples that I can crib from. Web 'tutorials' mostly just copy and paste man cron, which has zero examples. I'm just going to have to muddle through and rewrite them.

In Xubuntu I did 'sudo crontab -e,' and it had one small job: a monthly reminder to pay my T-Mobile bill, The daily jobs to back up /home and / were nowhere to be seen. There was also nothing in anacron. Yet, in Xubuntu /home and / were getting backed up every night, and there was another daily cron job to pop up a message with the date and rsync exit code. In Xubuntu every morning that message was on the middle of my screen. But right now I have no idea what was making the rsync scripts run in Xubuntu. Sparky's crontab is empty, so I can paste in the T-Mobile job from Xubuntu, but it looks like I'll have to rewrite the two backup jobs and the job to pop up the rsync exit codes.

There is a /var/spool/crontabs folder in Xubuntu's /, but it is empty. And I read about anacron and a couple more, but what I did before worked well. I have it on tomorrow's to-do list to reboot to Xubuntu, go to crontab -e, copy my jobs to a text file, and get back to Sparky. In theory that's all I need to do. It's taken about a week, but I'm almost done. And I'm liking Sparky more than Xubuntu. And there's nothing snapping at me or flat packages to deal with.

Yeah, both distros have /etc/cron/daily folders, which is where both cron jobs should be; they ran daily only. Most of the files are identical between the two distros. None have my name on them or anything that looks like it might be something that I produced. On Xubuntu I originally had 20.04, then 22.04, so if the timestamp on a file is before 2020 it couldn't be mine. But here's something that makes no sense: In the cron/daily folder for Xubuntu there is a file 'brave-browser ... 9.27.2023.' WTH? The last time I booted to Xubuntu was a week ago, for only a couple of hours, and the OS hasn't been run since. My gast is flabbered. The cron jobs were just one-liners in crontab, so an easier way to deal with this would be to boot to Xubuntu, run crontab -e, copy the jobs to a small text file somewhere accessible, then reboot to Sparky and paste them into Sparky's crontab-e.

[PLUG] Move cron jobs to new computer
Several years ago I created a couple shell scripts to make rsync create mirrors of / and /home on another drive installed in the computer. Although it took awhile I created cron jobs to run the scripts every day at 3am and 4am. My efforts worked perfectly for years, but now I'm migrating from Xubuntu 22.04.3 to SparkyLinux 7.0, and I'd like to migrate cron jobs in the process. SparkyLinux automatically mounts / and /home from Xubuntu, so I can just copy config files from the old OS to the new OS. However, I can't figure out where cron on Xubuntu kept the jobs.
