This link is too long for the commit message, but here is the commit 'du -A' was added to FreeBSD:
https://github.com/freebsd/freebsd-src/commit/fd543f275900cc66a0ce4725699f1e528e526792 -- 8< -- The --apparent-size option to 'du' was added in coreutils-4.5.8 (2003). FreeBSD 8.0 (2009) added the same functionality under the short option -A. This long option previously had no short option, so this patch adds -A to be compatible with FreeBSD. * NEWS: Mention the new short option. * doc/coreutils.texi: Document the short option. * src/du.c (usage): Likewise. (APPARENT_SIZE_OPTION): Remove definition. (EXCLUDE_OPTION): Define to CHAR_MAX + 1. (long_options): Use the -A short option for --apparent-size. (main): Likewise. --- NEWS | 3 +++ doc/coreutils.texi | 4 +++- src/du.c | 11 +++++------ 3 files changed, 11 insertions(+), 7 deletions(-) diff --git a/NEWS b/NEWS index 019451d32..2319e4517 100644 --- a/NEWS +++ b/NEWS @@ -33,6 +33,9 @@ GNU coreutils NEWS -*- outline -*- 'tail' now accepts the --debug option, which is currently used to detail the --follow implementation being used. + 'du' now supports the short option -A corresponding to the existing long + option --apparent-size, for compatibility with FreeBSD. + ** Changes in behavior 'timeout' now honors ignored signals and will not propagate them.
