I’m starting to learn perl, and I’ve found the perldoc intro/tutorial stuff to be pretty useful, but I’d like to get a good printed book or two to read through and use as a reference.

Similarly, while I’d say I’m pretty *NIX savvy, I’m not too familiar with some BSD-isms, particularly where they differ from Linux. Are there any good books out there to help with the transition from Linux to FreeBSD? (No, I’m not abandoning Linux… it’s just that my current employer used FreeBSD for many things.)

Any suggestions?
