So I've made a huge mistake and moved /lib and /opt folders to subfolder. Now almost every command returns "No such file or directory" or "/bin/sh: bad interpreter: No such file or directory". I need to move these files back, but I can't run mv. Can I do it somehow or should I start restoring server from backups?
My provider allowed external access to file system, so I was able to move directories to main directory and everything went back to normal:) Thanks for help.
