[SOLVED] I need a one time script to kick off after a reboot

Thaidog · 01-08-2014, 07:45 AM

What is the best method to kick off a one time script to run after a system has succesfully rebooted? I have an issue where VMware tools needs to be re-ran after I run yum update and reboot the VM. I was thinking an at job but what if the time to get the system up has passed the time supplied for the script to run?

Maybe you can use /etc/rc.local to kick of your script. The rc.local script is run once after all the rc stuff is done and before you can log in.

I just noticed you mention Gentoo as being your distro. I do believe Gentoo uses /etc/conf/local.start (or something similar) instead.

a working example I have used:

/root/runmeonce.sh:

Code:

#!/bin/bash
do stuff here...
chmod 0000 `basename $0`
# EOF

the

Code:

chmod 0000 `basename $0`

will make non-executable, so success "runs" won't do anything at all.

for the system to do it automatically, i would put it in /etc/rc.local.
for the user to do it once logged in you can put it in ~/.bash_profile.
some newer distros support a @reboot directive in the users crontab.

I went with the @reboot command thanks!

@Thaidog: If you consider this solved, can you put up the [SOLVED] tag?
