1 Executable programs or shell commands -----shell命令,ls2 System calls (functions provided by the kernel) ------系統調用,read,write
3 Library calls (functions within program libraries) -------庫調用
4 Special files (usually found in /dev)
5 File formats and conventions eg /etc/passwd
6 Games
7 Miscellaneous (including macro packages and conven?
