how to use md5sum on certain files

Question

Imagine I have a filelist like this:

file1.php
file2.php
login1.php
login2.php
logout1.php
logout2.php

And I want to do an md5sum on files called login* <- something like that. I need to count md5 of all files starting with login, continuing with whatever.

How do I do this, please?

Answer 1

md5sum login*

If that doesn't work, you're trying to take the md5sum of files that don't even exist.
