Michael Forney eb74f374f2 getconf: Add an explicit return at the end of main
ISO C does not require that main() have an explicit return value
(if the end of the main function is reached, it is as if it returned
0). However, when built as sbase-box, the main function is turned
into getconf_main, which does not have the same special treatment.

Michael Forney ba2f04f391 mknod: Use a switch statement for the node type 2020-03-01 16:33:18 -08:00
Michael Forney e5d8efb32f Import mknod from ubase
Although mknod is not a POSIX tool, it is widely available on nearly
all UNIX-like systems. It also can be implemented portably apart
from use of the makedev macros, which is already a requirement of
a couple other tools in sbase.

While we're at it, fix a few bugs:
- Include sys/sysmacros.h if makedev was not defined by sys/types.h
- The default mode should respect the user's umask, rather than
  assuming it is 022.
- Clear the umask when -m is specified explicitly so that nodes can
  be created with permissions wider than the user's umask.
- Utilize parsemode from libutil to support symbolic mode strings.

Michael Forney 22921a859f Fix various lint warnings in manuals
Fix "new sentence, new line" warnings throughout so that formatters
can produce correct spacing between sentences.

  Remove unnecessary Ns macros. These are not necessary for delimeters,
  which get special treatment.

  Fix date in manual. The contents were last modified on 2016-12-03,
  so use that instead of the invalid date.

  Fix escape sequence for `\<` and `\>`.

  Remove spurious `\\n` escape for the null-command.

Michael Forney 5c63ffad33 install: Fix -d with more than two directories
The `tflag || argc > 2` if-statement should only apply when not
creating directories (-d). Otherwise, if we are creating more than
two directories, we get an error if the last argument does not
already exist.

To fix this, move the -d case above and return early.

Michael Forney f3d05ffd0a chmod: Implement X perm symbol
Instead of clearing the format bits before calling parsemode, leave
them in so we can differentiate between directories and other files,
then clear the format bits in the result.

Michael Forney e5284b1537 sort: Don't do fallback top-level sort in check mode
The fallback useful to provide a consistent order of tied lines, but
in check mode, we don't want it to report disorder for equal lines
(according to the passed flags).

Thanks to Richard Ipsum for the bug report and proposed patch.

Michael Forney e9bfb97808 sort: Consider end field in keydef when additional fields are present
Currently, if the delimiter is found after the last field of a keydef,
only up to the beginning of the field is considered. This breaks `sort
-k N,N`, as well as whenever the sorted order comes down to that last

Thanks to Richard Ipsum for the bug report and proposed patch.

Michael Forney f4b9b966cf cp: Default to -P when -R is specified
POSIX only specifies the -H, -L, and -P options for use with -R, and
the default is left to the implementation. Without -R, symlinks must
be followed.

Most implementations use -P as the default with -R, which makes sense
to me as default behavior (the source and destination trees are the same).

Since we use the same code for -R and without it, and we allow -H, -L,
and -P without -R, set the default based on the presence of -R. Without
it, use -L as before, as required by POSIX, and with it, use -P to match
the behavior of other implementations.

Michael Forney 61f5d4887a wc: Removing output padding
Since the first column is not padded on the left, all the others will
not be aligned, so the padding isn't very useful.

POSIX says thet output should have the form

  "%d %d %d %s\n", <newlines>, <words>, <bytes>, <file>

so just do that.

Michael Forney 4f1d0df755 yes: Simplify, only support one argument
The previous code was too difficult to decipher for such a simple tool.

Since yes(1) is not specified in any standard and several well-known
implementations only support a single argument, do the same here.

Thanks to everyone who offered implementation suggestions in the email thread.

Michael Forney 39f92650d3 ls, tar: Guard inclusion of sys/sysmacros.h by absence of `major` definition
Since musl 1.1.23, it too does not provide `major` and `minor` through
sys/types.h, so instead include sys/sysmacros.h based on the absence of
`major` rather than only on glibc.

Thanks to Rich Felker for the suggestion.

Michael Forney d2824f5294 Revert "Do not use arg.h for tools which take no flags"
This reverts commit 9016d288f1.

Tools that have no options are required by POSIX to support "--" so
that conforming applications have a way to shield their operands from
implementations that provide options as an extension.

echo(1) is just an exception, so it is handled specially.

David Phillips 99c7876310 On glibc, include sysmacros.h directly
On glibc, major, minor, and makedev are all defined in
sys/sysmacros.h with types.h only including this for historical
reasons. A future release of glibc will remove this behaviour,
meaning that major, minor, and makedev will no longer be defined
for us without including sysmacros.h.
