BASH question

If I want to do a line count on all .c and .h files I can do this:

wc -l *.[ch]

*but* how do I add all .mdd files as well?

I tried wc -l *.[ch\"mdd\"]

also wc -- *.[ch&&"mdd"]

but obviously am missing something.

Behind the scenes, bash simply expands the string "*.[ch]" to
all files that match (all .c and all .h files), prior to passing the arguments
to "wc".
So, "wc -l" actually sees a list of all those files as input, not the "*.[ch]" string.
This implies that wc can handle any number of files given as arguments and so you might as well specify multiple filters as well:
wc -l *.[cd] *.mdd
should do the trick...

You could also use the cat command.

cat *.cd *.mdd | wc -l

Kinda weird, but I couldn't get the *.[***] to work. I get an error messages saying,
wc: *.[conf]: No such file or directory
