iii	How many lines are in the file? 4623
		wc
iv	Which burrito is more popular, steak or chicken? Steak = 368, Chicken = 553
		grep -c "Steak Burrito" chipotle.tsv

	MacBook-Pro:data Scott$ grep -c "Pinto Beans" chicburritocount.tsv

MacBook-Pro:data Scott$ grep -c "Black Beans" chicburritocount.tsv
282

		find . *.csv *.tsv
3	Count the number of occurrences of the word 'dictionary' (regardless of case) across all files in the DAT7 repo.
grep -c "dictionary" . *.csv *.tsv
