Bug fixes

  • df now fails when the list of mounted file systems (/etc/mtab) cannot be read, yet the file system type information is needed to process certain options like -a, -l, -t and -x. [This bug was present in "the beginning".]
  • sort -u could fail to output one or more result lines. For example, this command would fail to print "1": (yes 7 | head -11; echo 1) | sort --p=1 -S32b -u [bug introduced in coreutils-8.6]
  • sort -u could read freed memory [also introduced in coreutils-8.6]. For example, this command evokes a read from freed memory:

New features

  • rm now accepts the --dir (-d) option which makes it remove empty directories. This improves compatibility with Mac OS X and BSD systems which also honor the -d option.
