we move the folder by mistake as

mv /usr/lib64 /usr/lib64_bck

now we try to move back as

mv /usr/lib64_bck /usr/lib64

but we get

-bash: /usr/bin/mv: /lib64/ld-linux-x86-64.so.2: bad ELF interpreter: No such file or directory

any idea how to resolve it?

You need to manually specify the dynamic loader and library path:

LD_LIBRARY_PATH=/usr/lib64_bck /usr/lib64_bck/ld-linux-x86-64.so.2 /usr/bin/mv /usr/lib64_bck /usr/lib64

The way this works is as follows. mv can no longer run on its own, because its interpreter, /lib64/ld-linux-x86-64.so.2, has disappeared (on RHEL 7, /lib64 is a symlink to /usr/lib64); so instead of running mv directly, we run the interpreter, asking it to load mv:

/usr/lib64_bck/ld-linux-x86-64.so.2 /usr/bin/mv /usr/lib64_bck /usr/lib64

This will still fail because the dynamic linker can’t find the required libraries, so we specify the updated path, resulting in the command given at the top.

  • @yael that sounds like you should ask another question with the details of the issues... May 28, 2020 at 11:11
  • @yael I can’t remember how I figured out where you are (at least, what country you’re in), perhaps from a timezone? May 28, 2020 at 12:41
