See if your file-system has gotten hurt. Boot with init=/bin/bash and execute `/sbin/fsck -f /` to force a check of the root file-system.
The next check is to see if you can fix the protections when you are the only one accessing the file-system:
# mount -n -o remount / # re-mount root r/w # cd /usr # chmod 755 bin # ls -la # See if it worked # unmount /
The next check is to replace the /usr/bin directory. Since `mv` and `mkdir` are in /bin, the following should work.
# mount -n -o remount / # re-mount root r/w # cd /usr # mv bin foo # Rename 'strange' directory # mkdir bin # Make a new one # cd foo # Change to original # mv * ../bin # Rename all contents to new # cd .. # rmdir foo # Remove bad directory # chmod 755 bin # Fix protection # umount /
After you have fixed things, you don't have to re-boot. Just execute:
# exec /sbin/init auto
