Right. But that complicates the interface unnecessarily I think.

I'm going to apply the attached to give automatic support,
with the aforementioned caveat that BSD -r format checksums
where the _first_ file starts with a ' ' or '*' are not supported.
In that very unlikely case, one can always preprocess with sed 's/ /  /'

cheers,

Hi,

I have a little problem with md5sum.

A FreeBSD box generates an md5 sum of a file, which I'm later trying to
check on a Linux box. The problem is that what FreeBSD's md5 outputs is
slightly different from what Linux's md5sum expects, which makes md5sum
complain. The difference is really trivial: md5 outputs one space
between the sum and the file name, and md5sum outputs/expects two:

rq <at> garage:~/Pootle/tmp$ md5sum -c  catkeys.zip
md5sum: catkeys.zip: no properly formatted MD5 checksum lines found

rq <at> garage:~/Pootle/tmp$ md5sum -c  catkeys.zip.md5
md5sum: catkeys.zip.md5: no properly formatted MD5 checksum lines found

rq <at> garage:~/Pootle/tmp$ md5sum catkeys.zip
f653761af3137c8a631284b390bae102  catkeys.zip

rq <at> garage:~/Pootle/tmp$ cat catkeys.zip.md5
f653761af3137c8a631284b390bae102 catkeys.zip

I don't know which format is the "right" one, but could md5sum perhaps
be fixed to support md5's checksum files too?

Thanks!
Rimas Kudelis
