Swap the two last arguments of the current command line

Say you just typed a long command like this:

rsync -navupogz --delete /long/path/to/dir_a /very/long/path/to/dir_b

but you really want to sync dir_b to dir_a. Instead of rewriting all the command line, just type followed by , and your command line will read

rsync -navupogz --delete /very/long/path/to/dir_b /long/path/to/dir_a

Completly blank a disk

Instead of zeroing the filesystem, this command overwrites N times (default is 3) the disk content, making data recovery much harder.

The command accepts many more options

Rank top 10 most frequently used commands

I make an extensive use of sudo, so I had to exclude the sudo part of the command history
