gawk is installed.. I do fine when I just call gawk I get all the options to use with it but the minute I try to use the options with it I have problems. I have done it with batch files but then I would have to write out a batch file and then run the batch file. seems like more work than I should have to do to use options with a command line program.. I have done this in other cases with os.startfile and other cases and would like to fix it.
