debugging awk

From my experience, basic debugging techniques have always produced the desired results...not always quickly, though.<br>
<br>
If you are 'bailing' without actually running, then I would count your opening and closing braces, check for the proper usage and syntax of tests, keywords and punctuation. Cut out blocks and test again. I have found that removing all my productive blocks and debugging with just my conditional statments has saved me a lot of time, as I've found, this is where I make most of my mistakes. I embed sufficient prints to both let me know where it is, (once it stops bailing), and also to let me see the values I working with, once I can start putting productive blocks back in. <br>
<br>
I have not found or heard of any handy tools for debugging awk scripts but one could probably write an awk script to help do this but it would probably be difficult to debug.<br>
<br>
One other technique I find essential, is simply to walk away every once in a while.<br>
