A lot of the power of Git—especially when you need to untangle something—is hidden in the command-line interface (CLI). While CLI terminal software may seem intimidating, instructor Melanie Panem shows you ways to make your command-line interface environment more friendly and approachable to work in. Melanie explains various Git GUI software options and compares terminal program options. She walks you through the different shell environments and the common tools you might need. Melanie goes over the standard settings and preferences that are probably already available on your terminal, then dives into using and customizing a rudimentary version of your terminal’s shell, Bash. Once you’ve seen what Bash can do for you, she describes newer shells like Zsh and fish, which can be used to make Bash more efficient. Melanie finishes up by showing you the commands you need for CLI and Git.
