/lib has been moved accidentally
How to run all the commands in /bin and /usr/bin if the /lib has been moved accidentally 

 Scenario: 

 The /lib has been moved to /lib.old 

 If this has been done, all the commands like mv, ls and all that are in /bin and /usr/bin will not work since the /lib is needed 

 To resolve this and move back the /lib.old to /lib perform the following. 

 export LD_LIBRARY_PATH=/lib.old:/lib.old/x86_64-linux-gnu 

 /lib.old/x86_64-linux-gnu/ld-linux-x86-64.so.2  /bin/mv /lib.old /lib
