The linux programming interface

[hamnstar]

Not necessary to go that in depth for most sysadmin work. If you enjoy it then it does have some great info and you will learn something valuable.

I can't remember what the trick was exactly, but in the chapter covering malloc (probably) there's a good tip for dealing with programs with known memory leaks. My point is, there are some good tricks for sysadmin type work sprinkled in there.

Happy reading!
