trouble with awk

I am trying to figure awk.

I have a file in my home directory called testawk.sh, have made it executable, and have run it... But don't see any output.

This is the contents of the file:
Code:
#!/usr/bin/awk -f
{ print " - HI -" }

I enter ./testawk.sh in the prompt, press enter, and watch as the cursor blinks. And blinks. And blinks some more....

When I change the file to read:
Code:
#!/usr/bin/awk -f
BEGIN {print "a" }
{ print " - HI -" }

and run, it prints an 'a', a new line, and then the cursor starts to blink again.

What am I doing wrong?
