Hi,
This is possibly an easy thing to do but I’m fairly new to Linux so I’m not quite sure.
I need to run a shell script once when the system starts. How do I get that to happen?
I initially thought of using cron, but that seems to be for repeated tasks. So I then looked into using an entry in /etc/init.d/rc.5 (as an example) but those seem to be for ‘services’ which would seem to be over the top for what I want.
Is there a more commonly used option or is one of these the best way forward ?
I can’t put this into any logon processing for a user because the system in question is a server and hence on most times no user will logon.
a. Add your command to /etc/rc.local - this is the easiest
b. Write your own init script and install in init.d, then link to /etc/init.d/rc.d (on ubuntu, use “update-rc.d”)
c. Add to cron, with “crontab -e” (as root) then add “@reboot /” at the top, no time information
Many thanks for that, I used the “cron @reboot” option and it works a treat! My distro is SUSE v10.
Another question if I may.
In a script, how do I set the ‘current directory’ to be the one where the script is located? The situation I’ve got is as follows:
I use cron to run scripts as required
near the start of most of these I have a “cd” command to set the current directory. This allows my code which accesses files in the script directory to work fine.
as soon as I move the scripts or send them to a different machine (where I have no control over the directory names) then this is one thing that has to be changed.
I’m assuming that there will be a commend (or two) that I can use to “set current directory to thw one containing the script file”.
