Ok, So I've made my script, I dropped it in
/etc/cron.hourly then I
chmod 777 the file but it won't run (automatically). If I manually run it, it works fine. Do I need to do anything else?
cron.hourly are run by the run-parts mechanism (
man run-parts for more info). And
run-parts is choosy about what filenames it considers valid.
For example, giving your script an extension will make it invalid and result in the job not being run.
[a-zA-Z0-9_-] are the valid characters, so the '.' makes it invalid.
When adding a job to
/etc/cron.hourly ( or
.weekly, etc), always test afterwards that
run-parts will actually run it by issuing the command:
run-parts --test /etc/cron.hourly
If by running this command it shows your file it means it worked. Otherwise, if doesn't show anything your file name is not valid.
What was the name of your script?
DaithiF's answer should be the right answer.
Also, my script didn't have
#!/bin/bash in the first line. Even though the script could be executed with the command line,
run-parts rejected it saying "Exec format error".
Changing the file name from
scriptname and adding the
#!/bin/bash into first line enabled my script to run hourly.
In my case I made these errors due to which
cron.hourly wont execute my script:
I forgot to check if crond service is running:
systemctl status crond
I haven't added new empty line in the very end of my script file like cron's scripts in other folders have.
I created my script file using WinSCP on Windows thus inserted Windows-like EOL symbol, which cron can't interpret correctly. So I needed to execute
sed -i -e 's/\r$//' /etc/cron.hourly/myscriptto fix it.
