The GNU Core Utilities (coreutils) has announced the release of version 9.0 of “the basic file, shell and text manipulation utilities” used by the GNU operating system and various Linux distributions. In the year and a half or so since the last major release (8.32), various new features were added, including:
cp has changed how it handles data
- enables CoW [copy on write] by default (through FICLONE ioctl),
- uses copy offload where available (through copy_file_range),
- detects holes differently (though SEEK_HOLE)
- This also applies to mv and install.
