Noteworthy changes in release 9.1 (2022-04-15) [stable]

Bug fixes

  • chmod -R no longer exits with error status when encountering symlinks. All files would be processed correctly, but the exit status was incorrect. [bug introduced in coreutils-9.0]
  • If 'cp -Z A B' checks B's status and some other process then removes B, cp no longer creates B with a too-generous SELinux security context before adjusting it to the correct value. [bug introduced in coreutils-8.17]
  • 'cp --preserve=ownership A B' no longer ignores the umask when creating B. Also, 'cp --preserve-xattr A B' is less likely to temporarily chmod u+w B. [bug introduced in coreutils-6.7]
  • On macOS, 'cp A B' no longer miscopies when A is in an APFS file system and B is in some other file system. [bug introduced in coreutils-9.0]
  • On macOS, fmt no longer corrupts multi-byte characters by misdetecting their component bytes as spaces. [This bug was present in "the beginning".]
  • 'id xyz' now uses the name 'xyz' to determine groups, instead of xyz's uid. [bug introduced in coreutils-8.22]
  • 'ls -v' and 'sort -V' no longer mishandle corner cases like "a..a" vs "a.+" or lines containing NULs. Their behavior now matches the documentation for file names like ".m4" that consist entirely of an extension, and the documentation has been clarified for unusual cases. [bug introduced in coreutils-7.0]
  • On macOS, 'mv A B' no longer fails with "Operation not supported" when A and B are in the same tmpfs file system. [bug introduced in coreutils-9.0]
  • 'mv -T --backup=numbered A B/' no longer miscalculates the backup number for B when A is a directory, possibly inflooping. [bug introduced in coreutils-6.3]

Changes in behavior

  • cat now uses the copy_file_range syscall if available, when doing simple copies between regular files. This may be more efficient, by avoiding user space copies, and possibly employing copy offloading or reflinking.
  • chown and chroot now warn about usages like "chown root.root f", which have the nonstandard and long-obsolete "." separator that causes problems on platforms where user names contain ".". Applications should use ":" instead of ".".
  • cksum no longer allows abbreviated algorithm names, so that forward compatibility and robustness is improved.
  • date +'%-N' now suppresses excess trailing digits, instead of always padding them with zeros to 9 digits. It uses clock_getres and clock_gettime to infer the clock resolution.
  • dd conv=fsync now synchronizes output even after a write error, and similarly for dd conv=fdatasync.
  • dd now counts bytes instead of blocks if a block count ends in "B". For example, 'dd count=100KiB' now copies 100 KiB of data, not 102,400 blocks of data. The flags count_bytes, skip_bytes and seek_bytes are therefore obsolescent and are no longer documented, though they still work.
  • ls no longer colors files with capabilities by default, as file-based capabilties are very rarely used, and lookup increases processing per file by about 30%. It's best to use getcap [-r] to identify files with capabilities.
  • ls no longer tries to automount files, reverting to the behavior before the statx() call was introduced in coreutils-8.32.
  • stat no longer tries to automount files by default, reverting to the behavior before the statx() call was introduced in coreutils-8.32. Only stat --cached=never will continue to automount files.
  • timeout --foreground --kill-after=... will now exit with status 137 if the kill signal was sent, which is consistent with the behavior when the --foreground option is not specified. This allows users to distinguish if the command was more forcefully terminated.

New Features

  • dd now supports the aliases iseek=N for skip=N, and oseek=N for seek=N, like FreeBSD and other operating systems.
  • dircolors takes a new --print-ls-colors option to display LS_COLORS entries, on separate lines, colored according to the entry color code.
  • dircolors will now also match COLORTERM in addition to TERM environment variables. The default config will apply colors with any COLORTERM set.

Improvements

  • cp, mv, and install now use openat-like syscalls when copying to a directory. This avoids some race conditions and should be more efficient.
  • On macOS, cp creates a copy-on-write clone if source and destination are regular files on the same APFS file system, the destination does not already exist, and cp is preserving mode and timestamps (e.g., 'cp -p', 'cp -a').
  • The new 'date' option --resolution outputs the timestamp resolution.
  • With conv=fdatasync or conv=fsync, dd status=progress now reports any extra final progress just before synchronizing output data, since synchronizing can take a long time.
  • printf now supports printing the numeric value of multi-byte characters.
  • sort --debug now diagnoses issues with --field-separator characters that conflict with characters possibly used in numbers.
  • 'tail -f file | filter' now exits on Solaris when filter exits.
  • root invoked coreutils, that are built and run in single binary mode, now adjust /proc/$pid/cmdline to be more specific to the utility being run, rather than using the general "coreutils" binary name.

Build-related

  • AIX builds no longer fail because some library functions are not found.
