I put one script in /etc/init.d/abc.sh. Now I want it to run at startup.

How can I do that with chkconfig?

chkconfig --add abc.sh

But I am not sure how it works.

There's an old but still useful article at linuxjournal.com/article/4445 –  RedGrittyBrick Nov 13 '11 at 21:35

You can't unless you read /usr/share/doc/initscripts-*/sysvinitfiles and structure your script accordingly.

I often just use

/etc/rc.local

So, like...

echo "/etc/init.d/abc.sh" >> /etc/rc.local

should hack it for ya. There are probably more proper places, but whatever, it works, on most distros it seems.

that script is a daemon and i have abc start stop restart configurd –  Moorage Jul 12 '11 at 20:42

Have a look at other, existing init-scripts. In every proper rh-style init-script there are three hints: the runlevels, where the script should be started and the priority at which it should be started/stopped. The sum of start+stop should be normally 100.

This comment-line is evaluated by chkconfig.

Scripts which run on startup are not said to be a script — if you want the script to be executed at startup, change the following in /etc/crontab:

@reboot /path/to/script

You are on the right track. Your bash script is in the right location and you have added it to your chkconfig, which means your script is installed.

Please note that /etc/init.d is a symbolic link to /etc/rc.d/init.d

After adding your script, you need to select which runlevel you want to activate it on: chkconfig --level 35 abc on will activate your script on runlevels 3 and 5, your most common startups.

Please consult chkconfig --help for more info.

PS. you can also use ntsysv which is a tui for chkconfig.
