Aside from the material in this book, many other sources of information about
Linux system programming are available. This appendix provides a short introduc-
tion to some of them.

- Programs and shell commands: commands executed by users at the shell prompt.
- System calls: Linux system calls.
- Library functions: standard C library functions (as well as many other library
functions). - Special files: special files, such as device files.
- File formats: formats of files such as the system password (/etc/passwd) and
group (/etc/group) files. - Games: games.
