i still need to do some cleanup, but this is basically done. from here the only changes should be cosmetic. unless I... well, we find another dumb entry of mine. lol
but here it is.
This was actually a lot of fun for me. This is why I like Linux, and the Linux community.Code:#!/bin/bash

I have another script project I am working on for unknown IP addresses. but I will post that under its own thread. Probably tomorrow.
leon.p, and deck_luck, you guys are great. thanks for hanging in there with me.
kudos
When checking for the return value of rsync, you use '[ "$?" = "0" ]', but I would advice using '[ "$?" == "0" ]'.
I don't exactly recall how bash parses that, but most programming languages I know would interpret the single
'=' as setting the value of '$?' to '0', a process which also has a return value, which than gets checked by the 'if' statement.
This means that you don't check if the variable is zero, but set if to zero and then check if that worked.
