Fix md5.1 example

[gbe]

Summary

The last example in the manpage md5(1) wants to demonstrate GNU mode (md5sum) but uses BSD mode (md5) instead:

In GNU mode, the -c option does not compare against a hash string passed
as parameter. Instead, it expects a digest file, as created under the
name digest for /boot/loader.conf in the example above.

This example is still incorrect, md5 will take the file names to check from the digest file, not from the command line.

accidentally removed the newline in the edit suggestion above...

@des I am unsure, on how to update the example. I have tried it with these steps, which worked as expected besides the strange error message from md5sum.

gbe@fbsd-dev:~ % md5 /boot/loader.conf > digest
gbe@fbsd-dev:~ % md5sum -c digest /boot/loader.conf
/boot/loader.conf: OK
md5sum: WARNING: 22 lines are improperly formatted

I can't see how md5 would use a digest file.

What purpose does /boot/loader.conf serve here?

That is just the example that was used before. Could be any file, but the patch from the PR has taken this, since it was used in other examples.

You're missing the forest for the trees...

A proper fix for the problem is coming in a few seconds.

• Bump .Dd
• Fix the md5sum example
• Fix the md5 example when running in GNU mode (md5sum) the '-c' option expects a file containing the hash, but the file the hash is compared to is not needed since its already include in the digest file itself
