Subject: fileutils - df --histogram patch
I made this little patch because I get df output in my cron reports, and I
get lots of cron reports, so having a visual report is helpful. Anyway,
it adds an '--histogram' option to df. I'm not sure if it's unnecessary
bells & whistles or a genuinely useful feature. Anyway, I thought I'd
offer it and let you decide.
