Grep needs the text it is to search for as a quoted string.

On second thought, that is the directions I found on the net, but as there are no spaces it it it may work without them.
Test on your project and share.

 md5sum: standard input: no properly formatted MD5 checksum lines found

then I got Harold's message and that worked like a charm; although....

  • md5sum FileName | grep "96b13dbbc9f3bc569ddad9745f64b9cdb43ea9ae"
Why do you put the quotes in your text? I tried it w/o and with and it works both ways.

Either eyeball it, drop the md5sum in a file and -c it.  Or pull it into stdin somehow and don't give -c an argument.

jmcphee@mcphee ~ :) $ md5sum hosts.v2.dr
c941500d0f13118ead7c1d1eb79dec6b  hosts.v2.dr
jmcphee@mcphee ~ :) $ echo 'c941500d0f13118ead7c1d1eb79dec6b  hosts.v2.dr' | md5sum -c
hosts.v2.dr: OK

thanks James. I think the cksum is correct. So with the 'c' flag it will check each file against the checksums in a text file. I remember doing that with linuxfromscratch. What if you only have one sum? What flag should I enter.... well, let's check 'man'. Man says check info and info doesn't tell me. Is there a way to check one file easily?

The -c flag is for when the file you're putting is a text file with a bunch of checksums in it.  Simply do not use -c.

I downloaded a file and want to check it's sum to make sure it aI got a good D/L. I think I'm doing it wrong. I d/l the file and type in:

md5sum -c linuxmint-13-mate-dvd-64bit.iso
and md5sum seems to open the iso and check the files in it. Here is the output:

What am I doing wrong?
