These web pages contain tables of all the Commands and System interfaces defined in UNIX 98, complete with an indication of their availability in UNIX 95, the ISO POSIX-1 standard, the ISO POSIX-2 standard, the ISO C standard, SVID3 and 4.3BSD.

These are available as a single file in PDF or postscript. ( PDF viewers for 18 platforms are available from here ).

These tables are for the Single UNIX Specication Version 2 and UNIX 98, refer here for the tables for the Single UNIX Specification Version 3.

The System Interfaces are split into several tables and organized alphabetically:
