Decades of UNIX and Linux use have taught me to love the terminal more than any other app out there. If there's one thing I'd recommend any newcomer learn, it's how to tame the command line.

I just learned about the CLI tool `grex`. It might change how I approach regular expressions (🤞🙈). You provide string values and it comes up with a regular expression matching them.😲 github.com/pemistahl/grex Video alt: CLI session showing multiple generated reg. expressions.

Oh… Snap. The `gh` CLI tool has an API subcommand for interacting with the GitHub API directly. E.g., `gh api /orgs/$ORGrepos` Then slice and dice the data with `jq`.

One of the fights I keep losing at ${DAYJOB} is “don’t use short flags in shell scripts if you have long flags available; make things easier for the people who come after you” And like... I do not understand why this is controversial or why people resist it so strongly.

I very much recommend learning how to use a more well-structured scripting language than Bash, as languages such as Ruby have a great standard library, a huge ecosystem of other libraries, and are commonly installed across machines - this is a great look at partially replacing shell scripts with Ruby
