sed regex

hi, why isnt this working as i am expecting:
[schneidz@hyper temp]$ cat example.tmp
hello world
l33t h4x0rz
chun-li akuma
[schneidz@hyper temp]$ sed s/h*z/""/ example.tmp
hello world
l33t h4x0rz
chun-li akuma
i am expecting that the string h4x0rz does not come up in the output ?

sed 's/h.*z//' example.tmp
The '*' means zero or more of the preceding character, which is an 'h' in your example. The '.' matches any character. Placing the search in single quotes prevents interpretation by the shell.
