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
