Using jq and nvm to set Node version
The nvm command allows you to switch between versions of node. Often a project will include a .nvmrc file to specify the version of node to use. Even if a project does not contain an .nvmrc file, you may be able to read the preferred node version from package.json and use that value with nvm.

When working with Git on the command line, I spend a lot of time switching back and forth between two branches. Even with Git tab completion, it is a lot of typing. However Git has a shortcut for the previous branch, a single dash (-).
Curl Get Redirect
When creating 301 redirects, I often want to check multiple URLs quickly from the command line (to avoid the manual clicking in the browser and browser caching of results). I’ve written this script to speed up my process.
