i had to do a disk usage test because a server was filing up - i grepped for "G" but got some unnecessary data

so then i tried a grep '/[0-9].[0-9];[0-9]"G"/' and some other derivates but they did not work.

any ideas on regex expressions?

Don't bother trying to format in so-called "human readable" formats. I find it easiest to just let it default and (reverse) sort the result.

this is the command that everybody uses ' du --si | grep G ' - is there a better way to get the size. if it was just a raw number, that would be fine. then maybe i could 'sed10q' it just to get the top ten largest files. i do not know what the 'si' flag is. 'si' is not in the man pages, unless --si = -s -i.

i agree with you on the formats - i think the guys just need to send the higher ups a format that they can quickly understand. how would you get the disk usage for this drive and then reverse sort it?

Everybody ???. Not I.
--si should be in the manpage, right after "-h". Leave it out - try this (presuming reasonably current Linux and bash)
