Thanks centos2 .... but regarding your example, I cannot see where you configure that this services needs to be stopped before anyone else....

I don't have a CentOS 8 machine to test on but on a CentOS 7.9, this works for me:
/etc/systemd/system/shutdown-test.service
------------------------------------------------------ [Unit] Description=Remote copy some files before reboot/shutdown
[Service] Type=oneshot ExecStart=/bin/true ExecStop=/usr/local/bin/remote_copy RemainAfterExit=true
[Install] WantedBy=multi-user.target ------------------------------------------------------
the mode and contents of remote_copy:
-rwxr-xr-x 1 root root 44 Dec 22 08:23 /usr/local/bin/remote_copy
------------------------------------------------------ #!/bin/bash
date >> /tmp/remote_copy_result ------------------------------------------------------
After enabling the service and rebooting, I get a file in /tmp/remote_copy_result that contains the date.
My success is attributable not to me but to this post: https://unix.stackexchange.com/questions/39226/how-to-run-a-script-with-syst... Your unit file seems similar but when I used it, it didn't work on my CentOS 7.9 system either. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
