how to disallow all dynamic urls robots.txt
robots.txt
Solution
The answer to your question is to use
Disallow: /?q=
The best (currently accessible) source on robots.txt I could find is on Wikipedia. (The supposedly definitive source is http://www.robotstxt.org, but site is down at the moment.)
According to the Wikipedia page, the standard defines just two fields; UserAgent: and Disallow:. The Disallow: field does not allow explicit wildcards, but each "disallowed" path is actually a path prefix; i.e. matching any path that starts with the specified value.
The Allow: field is a non-standard extension, and any support for explicit wildcards in Disallow would be a non-standard extension. If you use these, you have no right to expect that a (legitimate) web crawler will understand them.
This is not a matter of crawlers being "smart" or "dumb": it is all about standards compliance and interoperability. For example, any web crawler that did "smart" things with explicit wildcard characters in a "Disallow:" would be bad for (hypothetical) robots.txt files where those characters were intended to be interpreted literally.
