Blocking directory and file scan with Fail2Ban

Hi,

I am trying to block some common directory scans and file scans
For example:

[Wed Jul 29 03:46:46 2015] [client 93.174.93.146] File does not exist: /htdocs/phpMyAdmin
or
[Sat Jul 11 07:08:24 2015] [client 93.88.143.179] script 'htdocs/scripts/setup.php' not found or unable to stat

As you see one is a directory /phpMyAdmin/ and the other is a file setup.php

I did find what I am looking for but I am a bit confused because I found 3 different syntaxes and are not sure which one is right. So my question would be which one of the 3 below is correct or maybe there is a better way all together.

Initially I found this at
http://www.fail2ban.org/wiki/index.php/HOWTO_apache_myadmin_filter

but even there are 2 versions and no real comment which one is actually right or if one is better than the other.

I know that some have more or less but the main issue I have is which is the right way. also what confuses me is that they specify the syntax with things like phpMyAdmin.* but the people do not scan for a file but a directory and file so I wonder what the right syntax is to block a file like setup.* and a directory like /phpMyAdmin/

Thank you for the assistance.

Best wishes,
