This feature makes it difficult for simplistic scripts to trivially
tabulate data with awk or sed. However, this feature is present in
SunOS and GNU df, so there is a good chance that portable scripts
can handle this format.
Someone mentioned POSIX in this thread. POSIX specifies a -P flag for
a portable output format intended for use by scripts. Although our df
does not support that flag (yet), it's current output almost conforms.
(As far as I can tell, it's simply a matter of changing "1K-blocks" to
Since there is (will be) a flag for portable output, and there is a
good chance that portable scripts already handle the "pretty" format,
I think a flag to enable the pretty format is probably not necessary.
I would support a change to make the pretty format the default.
