Hi there,

I’m migrating to a new theme, and needed to modify some Front matter variables in my posts.

I’m lazy and I don’t like Regex, so I searched for a tool to help me.

I found [yq](https://github.com/mikefarah/yq), a standalone CLI processor written in Go

The [official documentation](https://mikefarah.gitbook.io/yq/) is pretty unclear, so I wrote a post:

> **[Edit the Yaml Front Matter of multiple Markdown files](https://roneo.org/en/hugo-edit-yaml-files-from-the-cli-with-yq/)**
>
> Edit the Yaml Front Matter of multiple Markdown files - Roneo.org ✨

(I’m rebuilding the design of this site, things can be broken)

Many free text editors can do “Search and replace in the project.” The regular expression language allows us to make almost any substitution in strings. For example Visual Studio Code.
