Lets run those command on the machines

New instanceOld instance
find / -xdev | sort > new.txt find / -xdev | sort > old.txt

Pull the files locally

scp -i ~/.ssh/somekey [email protected]:/new.txt  /tmp/new.txt
scp -i ~/.ssh/somekey [email protected]:/old.txt  /tmp/old.txt

Then use this great delta tool to compare the files

delta -s /tmp/new.txt /tmp/old.txt
