Please help me, Its urgent.

I was in /tmp directory

and I accidentally executed as root

Code:

mv ../* .

export PATH=$PATH:/tmp/bin:/tmp/sbin:/tmp/usr/sbin:/tmp/usr/bin

/tmp/bin/mv /tmp/bin /tmp

Doesn't find, or won't run them successfully?

The stuff in /bin (now /tmp/bin) should be statically linked, and so should work even if /lib is now in /tmp/lib

You could of course try to play with the LD_* stuff to also point to /tmp/lib instead of /lib, but this type of scenario is precisely why some of the most essential utilities in /bin are statically linked.

Idle thought: if you chroot /tmp there is no way then to move stuff to its parent directory (-:

If all else fails, do you have a rescue CD you could boot to fix things?

I would think that it should be:

/tmp/bin/mv /tmp/bin /bin
or
/tmp/bin/mv -R /tmp/bin /bin

You may have to create the /bin directory first.

Untested - do not try it, just thinking.

 /tmp/bin/mv * ../
