EDIT:
A few more details: a user's personal services can (by default) be placed in $HOME/.config/systemd/user/ and managed accordingly with systemctl --user <commands>. No root needed just like with a personal crontab.

And check the file ownership of the output:
ls /tmp/infinite/date -rw-r--r-- 1 fiximan fiximan 300 Mai 28 14:31 infinite_date So the script is run by the correct user as set in the service file.
Of course you can stop and disable the service:

Maybe a short example for a systemd service will do.
This is our infinite script, location /path/to/infinite_script , executable bit set:
#!/bin/bash while ((1)) ; do date >> /tmp/infinite_date sleep 2 done No we need to define a service file:
[Unit] #just what it does Description= infinite date service [Service] #not run by root, but by me User=fiximan #we assume the full service as active one the script was started Type=simple #where to find the executable ExecStart=/path/to/infinite_script #what you want: make sure it always is running Restart=always [Install] #which service wants this to run - default.target is just it is loaded by default WantedBy=default.target and place it in /etc/systemd/system/infinite_script.service
Now load and start the service (as root):
systemctl enable infinite_script.service systemctl start infinite_script.service The service is running now and we can check its status
systemctl status infinite_script.service ● infinite_script.service - infinite date service Loaded: loaded (/etc/systemd/system/infinite_script.service; enabled; vendor preset: enabled) Active: active (running) since Tue 2019-05-28 14:18:52 CEST; 1min 33s ago Main PID: 7349 (infinite_script) Tasks: 2 (limit: 4915) Memory: 1.5M CGroup: /system.slice/infinite_script.service ├─7349 /bin/bash /path/to/infinite_script └─7457 sleep 2 Mai 28 14:18:52 <host> systemd[1]: Started infinite date service. Now if you kill the script (kill 7349 - main PID) and check the status again:
● infinite_script.service - infinite date service Loaded: loaded (/etc/systemd/system/infinite_script.service; enabled; vendor preset: enabled) Active: active (running) since Tue 2019-05-28 14:22:21 CEST; 12s ago Main PID: 7583 (infinite_script) Tasks: 2 (limit: 4915) Memory: 1.5M CGroup: /system.slice/infinite_script.service ├─7583 /bin/bash /path/to/infinite_script └─7606 sleep 2 Mai 28 14:22:21 <host> systemd[1]: Started infinite date service. So note how it was just restarted instantly with a new PID.
Of course you can stop and disable the service:
systemctl stop infinite_script.service systemctl disable infinite_script.service
