Title: Fantastic book
Review: Johnson and Troan is a great book for Linux programmers. It covers in good detail a wide range of topics in system programming, including process management, file and directory structures, linux development tools, signals, and terminal programming. Network programming is lightly covered, but network programming is a very large topic and is covered well in other books. Threads are also not covered, but again, threaded programming is a complex topic and is covered elsewhere. Johnson and Troan contains a long running example program, ladsh, which is a shell. This is a great example because developing a shell requires a high degree of interaction with the kernel and file system. The book does a great job of accurately covering the function prototypes for the core system library, including the many flags passed as parameters. Overall this is an excellent book, and it is one of the most frequently used programming texts on by shelf. I highly recommend it.
