问题
I set up some cronjobs a while back using crontab -e. My crontab includes the following line:
* * * * * /usr/bin/touch /home/blah/MADEBYCRON
It's been weeks since I did this. I have never seen /home/blah/MADEBYCRON. I set permissions on my home directory so it should be able to create files in this directory, so why does this file never exist?
/var/log/syslog does not exist.
回答1:
Ensure that the cron service is running. I use WSL with cron every day for my local backups using rsync so this should work.
Use which cron to check its installed, mine says /usr/sbin/cron.
Use crontab -l to list your configured jobs.
Use ps aux | grep cron to look see if cron is running, you should see /usr/sbin/cron if it is.
Use service cron status to check if the service is started.
Use sudo service cron start to start the cron service if it is not running.
