While uid_t and gid_t are both unsigned, the values (uid_t) -1 and
|
|
|
|
(gid_t) -1 are reserved. A uid or gid argument of -1 to the chown(2)
|
|
|
|
system call means to leave the uid/gid unchanged. Catch this case
|
|
|
|
so that trying to set a uid or gid to -1 will result in an error.

chown 4294967295 file

|
|
chown :4294967295 file

- Update to 8.16:
- Improvements:
* As a GNU extension, 'chmod', 'mkdir', and 'install' now accept
operators '-', '+', '=' followed by octal modes;
* Also, ordinary numeric modes with five or more digits no longer
preserve setuid and setgid bits, so that 'chmod 00755 FOO' now
clears FOO's setuid and setgid bits.
* dd now accepts the count_bytes, skip_bytes iflags and the
seek_bytes oflag, to more easily allow processing portions of a
file.
* dd now accepts the conv=sparse flag to attempt to create sparse
output, by seeking rather than writing to the output file.
* ln now accepts the --relative option, to generate a relative
symbolic link to a target, irrespective of how the target is
specified.
* split now accepts an optional "from" argument to
--numeric-suffixes, which changes the start number from the
default of 0.
* split now accepts the --additional-suffix option, to append an
additional static suffix to output file names.
* basename now supports the -a and -s options, which allow
processing of more than one argument at a time. Also the
complementary -z option was added to delimit output items with
the NUL character.
* dirname now supports more than one argument. Also the complementary
z option was added to delimit output items with the NUL character.
- Bug fixes
* du --one-file-system (-x) would ignore any non-directory
specified on the command line. For example, "touch f; du -x f"
would print nothing. [bug introduced in coreutils-8.15]
* mv now lets you move a symlink onto a same-inode destination
file that has two or more hard links.
* "mv A B" could succeed, yet A would remain.
* realpath no longer mishandles a root directory.
- Improvements
* ls can be much more efficient, especially with large directories
on file systems for which getfilecon-, ACL-check- and XATTR-
check-induced syscalls fail with ENOTSUP or similar.
* 'realpath --relative-base=dir' in isolation now implies
'--relative-to=dir' instead of causing a usage failure.
* split now supports an unlimited number of split files as default
behavior.
For a detaild list se NEWS in the documentation.
- Add up-to-date german translation.
- Add two upstream patches that speed up ls (bnc#752943):
* Cache (l)getfilecon calls to avoid the vast majority of the failing
underlying getxattr syscalls.
* Avoids always-failing queries for whether a file has a nontrivial
ACL and for whether a file has certain "capabilities".
