Using nothing but the power of the Bash command line, they slice and dice, pick and poke, and generally play around with a few data files from [Nashville’s Open Data Portal](https://data.nashville.gov/). You’ll learn you don’t need a lot of fancy tools to get the job done when you’re willing to put in a little work and embrace the Unix philosophy of combining simple, single-purpose command line programs. 0:00 Introductions 4:05 Nashville Open Data Portal 5:33 What is the Bash shell? 7:04 The difference between the shell and the terminal 8:29 What’s so great about Bash? 9:58 What’s the difference between Bash and Z shell?
