What is your problem? Where are you stuck? I guess the trailing asterisk in your first command might be too many.
Please post the contents and structure of the .md5 files, as well as the directory structures that you use.

md5
MD5(1) BSD General Commands Manual MD5(1)
NAME
md5 -- calculate a message-digest fingerprint (checksum) for a file
SYNOPSIS
md5 [-pqrtx] [-s string] [file ...]
DESCRIPTION
Md5 takes as input a message of arbitrary length and produces as output a 128-bit ``fingerprint'' or ``message digest'' of the input. It is
conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a
given prespecified target message digest. The MD5 algorithm is intended for digital signature applications, where a large file must be
``compressed'' in a secure manner before being encrypted with a private (secret) key under a public-key cryptosystem such as RSA.
MD5 has not yet (2001-09-03) been broken, but sufficient attacks have been made that its security is in some doubt. The attacks on MD5 are
in the nature of finding ``collisions'' -- that is, multiple inputs which hash to the same value; it is still unlikely for an attacker to be
able to determine the exact original input given a hash value.
The following options may be used in any combination and must precede any files named on the command line. The MD5 sum of each file listed
on the command line is printed after the options are processed.
-s string
Print a checksum of the given string.
-p Echo stdin to stdout and appends the MD5 sum to stdout.
-q Quiet mode - only the MD5 sum is printed out. Overrides the -r option.
-r Reverses the format of the output. This helps with visual diffs. Does nothing when combined with the -ptx options.
-t Run a built-in time trial.
-x Run a built-in test script.
