Recommended reading for Shell expansion mechanism

[Heiko Becker <heikobecker92@xxxxxxxxx>]

Hi all,

as I'm trying to give shell programming and things like that a start, I 
have a short question related to the shell expansion:

I heard that it is possible to exclude things after using a wildcard 
like ./* for every file in the current directory. Am I right or did I 
misunderstand something? Is there some place on the internet where I can 
find things about expansions and such operations of the shell?

Thanks in advance,

Heiko
