You can have as many regexps as you like.

Note that match starts at the beginning of the line. Hence (1) the ^ is 
superfluous and (2) 'eth0' must be at the beginning of the line to match. 
If 'eth0' is not at the beginning, the pattern should be '.*eth0'. Or you 
could use search instead of match, which looks thru the line for the pattern.
