Linux - Run Script after reboot
-
On windows you can add a registry key to run a command in the RunOnce option.
But what's the command/procedure for doing this on Linux???? I've got a script /tmp/set-up.sh that I need to run after a reboot when Root logs back in
-
I would use a cron job for this.

-
Cron is scheduled tasks for Linux. Definitely the way to do this.
-
Doesn't seem to be working.
systemctl status crond.service
shows cron is running.
crontab -e
added the line
@reboot /home/set-up.sh
but when I reboot and log back in as root nothing
guess i'm missing something -

What distro are you using?

The question should be: which cron? vixie, anacron, fcron or systemd maybe?

I suppose, the distro should have given us that info though.

I would assume systemd based on the above.

Reboot again and then post the output of
journalctl -u cron -n 25. -

guess i'm missing somethingI doubt /home/set-up.sh is the correct path, if it is, you need to create more users! Or did you mean /root/set-up.sh?

@travisdh1 Good eye. In the OP, he indicated /tmp, not /home.

But all on available Linux do.

Yes script runs and does what I want. I should of mentioned it has some prompts for user input.
It's a script to basically set-up networking on CentOS7 for basic IT Staff on new VM's so they don't have to edit the files direct.So I idea is once CentOS is installed add the script to start on next boot, shut the VM down then use it to clone new ones. As it will ask for hostname and static IP.

Interesting idea. Does it force it, or just remind to do it?

I'm with these two. Are you 100% you have the correct path?
-
I might implement a script like this. Care to share the script itself?

You could also use something like Ansible instead
