Find Duplicate Files (based on size first, then MD5 hash)

This is a modified version of the OP, wrapped into a bash function.

This version handles newlines and other whitespace correctly, the original has problems with the thankfully rare case of newlines in the file names.

It also allows checking an arbitrary number of directories against each other, which is nice when the directories that you think might have duplicates don't have a convenient common ancestor directory.

Unique sort

Uniq command is mostly used in combination with sort command, as

uniq removes duplicates only from a sorted file. i.e In order for uniq to

work, all the duplicate entries should be in the adjacent lines.

See who is using a specific port. Especially when you're using AIX. In Ubuntu, for example, this can easily be seen with the netstat command.
