I have an /etc/init.d/iptables start|stop|restart
script on different ubuntu servers (which is a normal shell script)
For each new service I have to edit and insert a line to open a port. This leads to many different versions of the init.d script on different machines.
Is it possible to automatically include let's say all files in /etc/iptables/include.d/
?
The target is that there should only a line in the start function of /etc/init.d/iptables like
include /etc/iptables/include.d/*
And after an additional file in /etc/iptables/include.d/
I'd simply say
/etc/init.d/iptables restart
Edit: As Saurabh pointed out this can lead to problems when commands need a certain order. An advanced setup could have different directories like:
/etc/iptables/include01.d/
/etc/iptables/include02.d/
/etc/iptables/include03.d/
and including them like this:
include /etc/iptables/include01.d/* ... maybe some code goes here in the main file... include /etc/iptables/include02.d/* include /etc/iptables/include03.d/*
