Linux - Run Script after reboot

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.

Doesn't seem to be working.

systemctl status crond.service

I would assume systemd based on the above.

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

added the line

@reboot /home/set-up.sh

but when I reboot and log back in as root nothing guess i'm missing something

Have you verified that the script can be run manually (have you set 'execute' permission)?

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

I 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.

Not every cron implementation supports @reboot states.

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

Not back in till Wednesday but it's a simple one so far

Asks for a hostname on a prompt and runs hostnamectl
Then asks for ip to assign and runs a few sed commands to edit the cfg-eth0 file.

So the main idea is to run the command/script when root logs in next.
