Save this script to a file named pattern, make it executable (chmod a+x pattern), and you 

can use it to perform your own tests:

$ ./pattern ' *' ' hello'

Matching against ' *' :

hello: Match.

$ ./pattern ' hello*' ' hello' ' hello, there' ' well, hello'

Matching against ' hello*' :

hello: Match.

hello, there: Match.

well, hello: No match.

Remember to use single quotes around the arg
