Paul Eggert d60b2922ff doc: modernize usage of “disk” and “core”
In documentation and comments, don’t assume that secondary storage
devices are disk devices.  Similarly, don’t assume that main memory
uses magnetic cores, which became obsolete in the 1970s.
* src/du.c (usage):
* src/ls.c (usage):
* src/shred.c (usage): Reword to avoid “disk” in usage messages.

These notes intend to help people working on the checked-out sources.
These requirements do not apply when building from a distribution tarball.
See also HACKING for more detailed contribution guidelines.
* Requirements
We've opted to keep only the highest-level sources in the GIT repository.
This eases our maintenance burden, (fewer merges etc.), but imposes more
requirements on anyone wishing to build from the just-checked-out sources.
Note the requirements to build the released archive are much less and
are just the requirements of the standard ./configure && make procedure.
Specific development tools and versions will be checked for and listed by
the bootstrap script. See README-prereq for specific notes on obtaining
these prerequisite tools.
Valgrind <http://valgrind.org/> is also highly recommended, if
Valgrind supports your architecture. See also README-valgrind.
While building from a just-cloned source tree may require installing a
few prerequisites, later, a plain 'git pull && make' should be sufficient.
* First GIT checkout
You can get a copy of the source repository like this:
$ git clone git://git.sv.gnu.org/coreutils
$ cd coreutils
As an optional step, if you already have a copy of the gnulib git
repository, then you can use it as a reference to reduce download
time and file system space requirements:
$ export GNULIB_SRCDIR=/path/to/gnulib
The next step is to get and check other files needed to build,
which are extracted from other source packages:
$ ./bootstrap
To use the most-recent gnulib (as opposed to the gnulib version that
the package last synchronized to), do this next:
$ git submodule foreach git pull origin master
$ git commit -m 'build: update gnulib submodule to latest' gnulib
And there you are! Just
$ ./configure --quiet #[--enable-gcc-warnings] [*]
$ make
$ make check
At this point, there should be no difference between your local copy,
and the GIT master copy:
$ git diff
should output no difference.
Enjoy!
[*] The --enable-gcc-warnings option is useful only with glibc
and with a very recent version of gcc. You'll probably also have
to use recent system headers. If you configure with this option,
and spot a problem, please be sure to send the report to the bug
reporting address of this package, and not to that of gnulib, even
if the problem seems to originate in a gnulib-provided file.
* Submitting patches
If you develop a fix or a new feature, please send it to the
appropriate bug-reporting address as reported by the --help option of
each program. One way to do this is to use vc-dwim
<https://www.gnu.org/software/vc-dwim/>), as follows.
Run the command "vc-dwim --initialize" from the top-level directory
of this package's git-cloned hierarchy.
Edit the (empty) ChangeLog file that this command creates, creating a
properly-formatted entry according to the GNU coding standards
<https://www.gnu.org/prep/standards/html_node/Change-Logs.html>.
Make your changes.
Run the command "vc-dwim" and make sure its output (the diff of all
your changes) looks good.
Run "vc-dwim --commit".
Run the command "git format-patch --stdout -1", and email its output
in, using the output's subject line.
