* Noteworthy changes in release 8.10 (2011-02-04) [stable]
** Bug fixes
du would abort with a failed assertion when two conditions are met:
part of the hierarchy being traversed is moved to a higher level in the
directory tree, and there is at least one more command line directory
argument following the one containing the moved sub-tree.
[bug introduced in coreutils-5.1.0]
join --header now skips the ordering check for the first line
even if the other file is empty. [bug introduced in coreutils-8.5]
rm -f no longer fails for EINVAL or EILSEQ on file systems that
reject file names invalid for that file system.
uniq -f NUM no longer tries to process fields after end of line.
[bug introduced in coreutils-7.0]
** New features
cp now copies sparse files efficiently on file systems with FIEMAP
support (ext4, btrfs, xfs, ocfs2). Before, it had to read 220 bytes
when copying a 1MiB sparse file. Now, it copies bytes only for the
non-sparse sections of a file. Similarly, to induce a hole in the
output file, it had to detect a long sequence of zero bytes. Now,
it knows precisely where each hole in an input file is, and can
reproduce them efficiently in the output file. mv also benefits
when it resorts to copying, e.g., between file systems.
join now supports -o 'auto' which will automatically infer the
output format from the first line in each file, to ensure
the same number of fields are output for each line.
** Changes in behavior
join no longer reports disorder when one of the files is empty.
This allows one to use join as a field extractor like:
join -a1 -o 1.3,1.1 - /dev/null
