Works even if file name contains \n. Spawns one job per core.

If you have two sets of files that may share hard-linked files, it can be useful to identify which ones are hard links to same underlying inode (file). This command shows you all of those, sorted by inode#. In my example the two directory trees to compare share a common parent, so I run the command in that parent and just use find . to start from the current directory. If yours are in different locations, you can pass both paths to find: find /directory1 /directory2 -type f -printf '%10i %p\n' | sort | uniq -w 11 -d -D | less Show Sample Output

Splitting on tags in awk is a handy way to parse html.

Applying filter rules is what makes this a really useful command. It's usually a pain to figure out how to sync ONLY files matching a particular pattern, and often one reverts to goofy stuff like find .. -exec rsync .. The filter hides all folders from the transfer, so that only the matching folders that store the filename are left for the sync.

Change the IP address from 127.0.0.1 to the target machines ip address. Even if the target has ICMP (ping) blocked, it will show you what ports are open on the target. Very handy for situations where you know the target is up and online but wont respond to pings. Show Sample Output
