Look: if you're a Unix sysadmin, you need this book. It really is that simple.

If you're a sysadmin, your expertise might be limited -- as mine was -- to something like "%wheel ALL=(ALL) ALL", then making sure you're in the wheel group. But sudo can do more, so very much more. Did you know that sudo -i can replace "sudo su -"? I didn't. How about sudoreplay, which lets you see exactly what someone did to bring down the system? News to me. Michael W. Lucas takes us through sudo from start to finish, from local files to LDAP, from let-the-sysadmin-do-anything to precisely delimited DBA-appropriate commands, and explains the wherefores, the whys and the WTFs along the way. He's careful, he's precise, and he lets you know the shortcomings that inevitably accompany any problem's solution.
Lucas' writing is great, as always. I've read many of his books, and I enjoy the way he will step back and bring some levity. If that's not your cup of tea, I suppose you could pass this up...but man, you'd be missing out.
It's awesome, it's Lucas, it's sudo. Buy it now.
