I'm having some difficulty using md5sum to verify some copied files.

I have two directories: dir1 and dir2. In dir1 there are five files: file1, file2, file3, file4 and file5. dir2 is empty.

If I do: cp dir1/* dir2,

then: md5sum dir1* > checksums,

then: md5sum -c checksums,

the result is:

dir1/file1: OK
dir1/file2: OK
dir1/file3: OK
dir1/file4: OK
dir1/file5: OK

But this is no good. I want it to compare the checksums in the text file with the checksums of the copied files in dir2.

It seems like the answer is obvious and I'm being really stupid.
