Talking md5sum -c errros

Ok, I have never posted on a forum before because I have always been able to figure out my issue before it came to that. But now I'm dead in the water with this program I'm trying to write.

I was asked by a co-worker to write a script that would check the hash keys of database files in a given directory. Before I write any script I run the commands in a term to ensure they will work. I was able to run
md5sum "directory" >> md5sum.txt. This gave me the all the hash keys for the files and put them in their own folder. I did the same for the files I was trying to compare them to.
md5sum "directory" >> md5sumb.txt

This worked as well, but when I try and run

md5sum -c md5sum.txt md5sumb.txt all I get are errors saying either the
"filename: No such file or directory".
"FAILED open or read"

I have been banging my head on the wall and trolling forums for almost a week now and I can not find any help with my situation. Every forum I pull up is about people only using md5sum for .iso files or cd's. Is this just not the command I should be using to compare txt files? Or am I just retarded and not seeing what I'm doing wrong. I have never been able to get the -c flag to work....HELP!!!!

After you saved the hashes for files in a directory (I prefer 'md5deep -r /some/path > /path/to/md5sum.txt') you should be able to verify them hashes with 'md5sum -c /path/to/md5sum.txt' NP. Unless you actually meant you wanted to compare file contents ('man diff') that is...

Hello UnSpawn,

Thank you so much I actually figured it out yesterday before I left work, but you are right it was because inside the md5sum.txt file I did not have the path to the database files. Once I threw those in there I was able to use the -c. But thank you anyway. : )
