How to restore system? messed up libs. [solved]

Em.. I exidently moved some libs, somewhere. Don't know how exactly, I was playing with sasl in

/usr/lib/sasl2/

I backed up sql libs to sql folder

mkdir sql
cp mysql* sql/*

then I deleted sql libs for testing purposes, and after a while I came back to this directory, to restore libs.

inside /usr/lib/sasl2/ I executed

mv /sql/* ../*

I might have misstyped something, but I'm not sure because after that the system went down. nothing worked pacman said I missing some libs, wget said I'm missing some libs, ls command didint worked /bin/ls no such file or directory and so on. now the system won't even start, says grub error 15.

I could reinstall the system, but I'd learn the approach to fix something like this

First make sure that you still have the required files in the directory you made first by

 ls /usr/lib/sasl2/sql

then

mv /sql/* ../*

Should read

mv sql/* ./

That's assuming that you are in /usr/lib/sasl2/

/sql = /sql
where in this case
sql = /usr/lib/sasl2/sql

I understand all that, and thats why its so interesting why everything stopped working if in worst case scenario I only messed sasl2 libs.

every command stoped working, I could not execute even "ls" which said /bin/ls no such file or directory.

I'll try to boot from usb, mount hard drive and check if files are there or something, I was running couple services like postfix and bind with public access without finishing confugring them. maybe it was just coincidence that I was playing with libs, and I was actually hacked

You have to be very careful using mv command [I prefer to cp! just in case]

Try chrooting in [see wiki!] to fix some of the problems to get booting system

Failing that backup important files configs etc and reinstall

I booted from arch usb, mounted partition to check whats there, and it looks weird, I got only "dev lib proc sbin srv sys tmp usr var". can't figure out what happened which log should I check and what to look for?
