This manual was originally derived from the Unix man pages in the distributions, which were written by David Mac Kenzie and updated by Jim Meyering.What you are reading now is the authoritative documentation for these utilities; the man pages are no longer being maintained.Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, with no Front-Cover Texts, and with no Back-Cover Texts.A copy of the license is included in the section entitled “GNU Free Documentation License”.
This manual is a work in progress: many sections make no attempt to explain basic concepts in a way suitable for novices.
Thus, if you are interested, please get involved in improving this manual. The GNU utilities documented here are mostly compatible with the POSIX standard. Include the version number, machine architecture, input files, and any other information needed to reproduce the bug: your input, what you expected, what you got, and why it is wrong.
The original man page was written by Ross Paterson.
François Pinard did the initial conversion to Texinfo format.
Karl Berry did the indexing, some reorganization, and editing of the results.
Brian Youmans of the Free Software Foundation office staff combined the manuals for textutils, fileutils, and sh-utils to produce the present omnibus manual.
