A Unix shell question

I signed up for the unix website but it sucks: I can't post anything in it at all and it's very slow.

If anyone knows a good unix furum for beginners, i'd like to know.

What does * mean when you run a program that needs an argument and you provide it with * as argument?

* is a wildcard operator, e.g.

Code:

grep string file.txt

will look for "string" in file.txt, while

Code:

grep string *

will search for "string" in all files in the current directory.

Linuxquestions is a great site to ask about shell programming.... we have our own programing forum after all.
