Isilon OneFS luxisi-1 v6.5.4.5 Isilon OneFS v6.5.4.5 B_6_5_4_85(RELEASE): 0x605040000500055:Tue Nov  1 15:08:16 PDT 2011    root at fastbuild-06.west.isilon.com:/build/mnt/obj.RELEASE/build/mnt/src/sys/IQ.amd64.release amd64
>Description:
FreeBSD 'md5' should include the --check option. We use this frequently to verify the integrity of archives (we actually use a custom-built port of GNU 'md5sum').

Please add --check functionality for checking files against 'md5' (or 'md5sum') output.

Thanks!
>How-To-Repeat:
luxisi-1# md5 --check xsq.md5
md5: illegal option -- -
usage: md5 [-pqrtx] [-s string] [files ...]

>Fix:
Add --check capability, equivalent to GNU md5sum.
