Running script as user with root permissions
Solution 1:
One way would be to create a systemd unit.
All the possible options you can find here: www.freedesktop.org/.../systemd.unit.html
but I am going to present simple example:
1.Lets create a bash script which will write the date and time of each system bootup to the file: /root/file
Only root
user has permissions to write and edit files in /root
directory.
I am going to switch user to the root
with sudo su -
Lets create a script /root/timelog.sh
and make it executable chmod +x /root/timelog.sh
#!/bin/bash
if ! [ /root/file ]; then touch /root/file; fi
echo $(date) >> /root/file
2.Now we need the System Unit
file: /etc/systemd/system/timelog.service
[Unit]
Description=timelog.service
[Service]
Type=oneshot
ExecStart=/root/timelog.sh
[Install]
WantedBy=multi-user.target
3.Last task is to make sure it will start with the system:
systemctl enable timelog
