accidentally lost rc.local

[Guest bonzai]

While trying to add a few route add's to my rc.local file via WinSCP, this program crashed and when I reconnected rc.local was completely empty !

Is there a way to recreate this file and have full functionality again after reboot ? I have a backup from 2 months ago, would it be safe to use that one or would I lose some stuff?

I'm a little desperate to know what's best here...

All help welcome...thx

yes, it is perfectly safe to use your rc.local backup copy. But if you want to use the default one you can find it in initscripts rpm package (1). rc.local is a file that usually isn't modify often.

 

(1) Here is a way to extract that file w/o having to reinstall the full rpm package:

~$ rpm2cpio ftp://WHATEVER_RPM_MIRROR/initscripts-your_version.rpm |cpio -idv rc.local && cp -i ./etc/rc.local /etc

In the example, I'm using a rpmpackage from the net, but you may have your own mdk-CDROM at hand.

oops, pmpatrick you were faster ;)

[offtopic]The trick, if any is inerested could be something like this (I believe I posted it somtime ago in tips&tricks):

rpm_fastextr () {
   # usage: rpm_fastextr fullpath/rpmpackage filetoextract
   local rpm_pkg="$1" file="$2" timeout=${3:-10}
   rpm2cpio $rpm_pkg | cpio -idv "*${file}" 2>&1 | tee rpm2cpio.out & while :; do
       if grep "${file}"; then
           sleep $timeout;
           killall rpm2cpio;
           break;
       else
           sleep 2;
       fi;
   done
}

Using it you'll ensure that rpm2cpio stops just after finding the file you want and don't parses the full rpm package.
