Every command returns "No such file or directory" or "/bin/sh: bad interpreter: No such file or directory"

  • 772

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?

EDIT:

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.

  1. You might be able to undo the move by something like:

     export LD_LIBRARY_PATH=/subfolder/lib
 /subfolder/lib/ld-linux.so.2 /bin/mv /subfolder/lib /lib

    ...replacing /subfolder with whatever directory you moved /lib into. If a 64-bit Linux host, try ld-linux-x86-64.so.2 instead.

    I haven't fully tested this, because I'm not going to break a system in order to do so!

    Step 1: Boot from live-cd...

    Step 2: Mount the Hard Disk

    Step 3: and move the files back.

    Step 4: NEVER do that again.

    (if you need specific instructions... just ask)

  3. Don't logout that Putty session ! You probably won't be able to get back into the server.

    Can you run busybox ? (it usually lives in /bin so try "/bin/busybox")

    Busybox is almost completely self-contained and has build-in versions of most standard Unix commands'. Busybox without any parameters gives you a list of all commands that it can emulate.

    You run the commands like "/bin/busybox {command} ".

    E.g.: "/bin/busybox mv file1 file2"

    If you have it on the system you can probably use it to move everything back to the original locations.

  4. You have a tool called sln which is a statically linked ln. You can use this one to symlink the folders to the previous place, and then work from there. So say, if you moved /lib to /datadrive/lib and then you broke the system, you could type this to temporarily fix it:

    sln /datadrive/lib /lib

    Do this for each library path you might have moved.
