Subject: bug#20936: suggestion for a 'wart-ish' extension off of 'sort'
Date: Tue, 30 Jun 2015 00:28:09 -0700

I admit the ability to show a summary line might not bethe first
thing you'd think a pure-sorting utility might do, but it would be
awfully handy if sort had a 'Numeric sum' option ("-N" -- preferred
'-s', but it's already taken) to go with the -h sorting:

ala:

I'd donate the code for hsort, but its in perl --
I wrote it several years ago to do what 'sort -h' does, but
also put in the option for a summary line -- handy companion
for 'human numbers', which would otherwise take alot more
typing (I think -- unless there's some hidden switch I don't know
about).
