One of the more intriguing capabilities of the BSD operating systems is their ability to run binaries for other Unix-like operating systems. I recently found myself requiring the commercial PGP Command Line for a project. Rather than install a Linux box just for this one piece of software, I jumped through some hoops and made it work perfectly on one of my existing FreeBSD systems. Getting a random piece of commercial Linux software running on a FreeBSD system isn't always as transparent as you might like, but you can do it with a minimum of fuss if you have a few extra troubleshooting skills.
