Basically I am wondering about some syntax issues.  The below htaccess file works fine for me.
However I have seen things written differently elsewhere and am wondering why it matters.

Here are some examples:
I have seen  mydomain\.com and mydomain.com
When do I need to use the "\"?
I have also seen (.*) and then ^(.*), what is the different here?
Also I have seen is there the ending "$" is not included at all, any reason for this?

If you could check the syntax of my code below and suggest changes let me know.

0 RewriteEngine on
1 RewriteCond %{HTTP_HOST} !^www.maindomain.com$ [NC]
2 RewriteCond %{REQUEST_URI} !^/robots\.txt$
3 RewriteRule (.*) http://www.maindomain.com/$1 [R=301]
4
5 #If robots.txt is requested from anything other than maindomain send new txt file.
6 RewriteCond %{HTTP_HOST} !^maindomain\.com
7 RewriteRule ^robots\.txt /robots_noindex.txt [L]

the \ means the period afterwards will mean a period character otherwise it will mean ANY character, so you must 'escape' it.

^ means the beggining of the string also $ means the end of the string.
