I just downloaded KNOPPIX_V3.3-2003-11-19-EN.iso and KNOPPIX_V3.3-2003-11-19-EN.iso.md5 again (needed to burn a new copy at home).

cat KNOPPIX_V3.3-2003-11-19-EN.iso.md5 returns
8f841bae907f828ed7a36a0213746ab1 *KNOPPIX_V3.3-2003-11-19-EN.iso but

md5sum KNOPPIX_V3.3-2003-11-19-EN.iso returns
8f841bae907f828ed7a36a0213746ab1 KNOPPIX_V3.3-2003-11-19-EN.iso

I never noticed that "*" in KNOPPIX_V3.3-2003-11-19-EN.iso.md5 before. Is this normal? If so, what is that "*" about? If not, does that mean my md5sum is bad so I should download again?

TIA,
AJG

No - it should be fine. :)

Wow, Ricky, thanx for that fast response!

But, what is that "*" about???

TIA,

Obviously the * can't be a part of the hash, so I'm sure the ISO is OK.

Oh, OK, I thought undocumented features only came with Mr. Gates' Evil OS....

I only know this because I was asked to develop a proof of concept in Perl to prove that binary files could be stored in a Oracle DB and we could guarantee that the file is the same after it was retrieved. I am not trying to be an annoying know-it-all.


MD5SUM command uses the asterix * to designate that it is a binary file OR if the file was read in binary mode.

Doing man md5dum in Cygwin on Windows2000 shows:


-b, --binary
read files in binary mode (default on DOS/Windows)

-c, --check
check MD5 sums against given list

-t, --text
read files in text mode (default)


http://www.fifi.org/cgi-bin/man2html/usr/share/man/man1/md5sum.1.gz shows:
-b
Use binary mode. In unix environment, only difference between this and the normal mode is an asterix preceding the filename in the output.

I hope this makes sense.
