@derek I prefer sed.
@derek don't forget sed
@derek The print statement at about 13 minutes should actually read:
print "The square root of", i*i, "is", i;
@derek I'm glad you did this on Awk. I know everyone for some reason like sed. However I have always like AWK much more since it's similar to other languages I have used and use today. AWK complements C pretty good howver I have also been enjoying lua and think lua is a better drop in replacement for both awk and sed then again I guess one could say the same about python or any other scripting langague that can run from the console. I guess it really comes down to preference.
@derek I disagree that it's 'essential'.
