Scheduled tasks

Anacron jobs

Files under /etc/cron.xyz (i.e. daily) dirs.
These files have to be executable, owned by root, not writable by group or other.
Symlinks have to point to files owned by root.
File names must be made up of letters, digits, underscores or hyphens only.

Test (manually run) scripts.

sudo run-parts /etc/cron.daily

note

Tested on Fedora 29.

Redirect STDOUT and STDERR to a file.

* * * * * myjob.sh >> /var/log/myjob.log 2>&1

note

Whether cron tried to execute the job is stored in /var/log/syslog or /var/log/cron.log.
