The Basics

Filter files

To generate a list of all burrito orders, we can use grep to filter lines using a pattern of interest:

grep "Burrito" orders.tsv

Note that grep is case-sensitive, i.e. the following won’t return any results:

grep "burrito" orders.tsv

But we can ask grep to ignore the case of our pattern:

grep -i "burrito" orders.tsv

Another common pattern of inquiry is to find lines that do not match a pattern. To find all orders that are not burritos:

grep -v "Burrito" orders.tsv
