1 These are the GNU core utilities. This package is the union of
2 the GNU fileutils, sh-utils, and textutils packages.
4 Most of these programs have significant advantages over their Unix
5 counterparts, such as greater speed, additional options, and fewer

22 If you obtained this file as part of a "git clone", then see the
23 README-hacking file. If this file came to you as part of a tar archive,
24 then see the file INSTALL for general compilation and installation
25 instructions, or README-install for system and coreutils specific instructions.
27 Like the rest of the GNU system, these programs mostly conform to
28 POSIX, with BSD and other extensions. For closer conformance, or
29 conformance to a particular POSIX version, set the POSIXLY_CORRECT
30 and the _POSIX2_VERSION environment variables, as described in
31 the documentation under "Standards conformance".
33 The ls, dir, and vdir commands are all separate executables instead of
34 one program that checks argv[0] because people often rename these
35 programs to things like gls, gnuls, l, etc. Renaming a program
36 file shouldn't affect how it operates, so that people can get the
37 behavior they want with whatever name they want.
39 Special thanks to Paul Eggert, Brian Matthews, Bruce Evans, Karl Berry,
40 Kaveh Ghazi, and François Pinard for help with debugging and porting
41 these programs. Many thanks to all of the people who have taken the
42 time to submit problem reports and fixes. All contributed changes are
43 attributed in the commit logs.
45 And thanks to the following people who have provided accounts for
46 portability testing on many different types of systems: Bob Proulx,
47 Christian Robert, François Pinard, Greg McGary, Harlan Stenn,
48 Joel N. Weber, Mark D. Roth, Matt Schalit, Nelson H. F. Beebe,
49 Réjean Payette, Sam Tardieu.
51 Thanks to Michael Stone for inflicting test releases of this package
52 on Debian's unstable distribution, and to all the kind folks who used
53 that distribution and found and reported bugs.
55 Note that each man page is now automatically generated from a template
56 and from the corresponding --help usage message. Patches to the template
57 files (man/*.x) are welcome. However, the authoritative documentation
58 is in texinfo form in the doc directory.
65 If you would like to add a new feature, please try to get some sort of
66 consensus that it is a worthwhile change. One way to do that is to send
67 mail to coreutils@gnu.org including as much description and justification
68 as you can. Based on the feedback that generates, you may be able to
69 convince us that it's worth adding. Please also consult the list of
70 previously discussed but ultimately rejected feature requests at:
71 https://www.gnu.org/software/coreutils/rejected_requests.html
78 Send bug reports, questions, comments, etc. to bug-coreutils@gnu.org.
79 To suggest a patch, see the files README-hacking and HACKING for tips.
81 All of these programs except 'test' recognize the '--version' option.
82 When reporting bugs, please include in the subject line both the package
83 name/version and the name of the program for which you found a problem.
85 If you have a problem with 'sort', try running 'sort --debug', as it
86 can often help find and fix problems without having to wait for an
87 answer to a bug report. If the debug output does not suffice to fix
88 the problem on your own, please compress and attach it to the rest of
91 IMPORTANT: if you take the time to report a test failure,
92 please be sure to include the output of running 'make check'
93 in verbose mode for each failing test. For example,
94 if the test that fails is tests/df/df-P.sh, then you would
97 make check TESTS=tests/df/df-P.sh VERBOSE=yes SUBDIRS=. >> log 2>&1
99 For some tests, particularly perl tests, you can get even more detail by adding
100 DEBUG=yes. Then include the contents of the file 'log' in your bug report.
103 ***************************************
105 There are many tests, but nowhere near as many as we need.
106 Additions and corrections are very welcome.
108 If you see a problem that you've already reported, feel free to re-report
109 it -- it won't bother us to get a reminder. Besides, the more messages we
110 get regarding a particular problem the sooner it'll be fixed -- usually.
111 If you sent a complete patch and, after a couple weeks you haven't
112 received any acknowledgement, please ping us. A complete patch includes
113 a well-written ChangeLog entry, unified (diff -u format) diffs relative
114 to the most recent test release (or, better, relative to the latest
115 sources in the public repository), an explanation for why the patch is
116 necessary or useful, and if at all possible, enough information to
117 reproduce whatever problem prompted it. Plus, you'll earn lots of
118 karma if you include a test case to exercise any bug(s) you fix.
