FreeBSD POSIX 2001 Utility Compliance

This page is maintained by Jens Schweikhardt, please send comments, corrections and updates to me. Thanks!

The next generation POSIX standard, termed IEEE Std 1003.1-2001 or POSIX 2001 for short, is complete. POSIX 2001 specifies (among other things) the names and options of a number of command line utilities.

FreeBSD aims to be as compliant as possible with only a minimized area of non-compliance. The following is the result of a comparison of the utility names and options as found on FreeBSD 5.0-current (as of April 2002) and the final draft 7 of the POSIX 2001 document. It is intended as a clearinghouse for anyone seeking information on FreeBSD's utilities compliance to POSIX 2001. (Note that a lot of non-compliance issues have been resolved in 5-current in the meantime. Compare with the Conformance Project's list of task. The final conformance description of FreeBSD 5.x will be documented in the posix(7) manual page.) If you are looking for a userland hacking job, the following serves as a list of areas where help is needed. Some utilities don't exist at all, some are found in the ports collection, some are missing one or more options, some have options that do something different.

POSIX 2001 makes some functionality optional, depending on support for various extensions. Optional functionality is marked by shading in the original POSIX document and associated with the particular extension by means of an abbreviation. The same abbreviations also appear in the comparison below.
