      <p>As well as PHP, JavaScript, HTML, CSS, etc, I write a lot of Bash scripts.</p>

      <p>From <a href="/daily/2022/08/15/using-run-file-simplify-project-tasks">project-specific run files</a> to CI pipelines, Dockerfiles and deployment scripts, Bash is used a lot in the ops side of software development.</p>

      <p>Today, though, I wrote <a href="https://github.com/opdavies/dotfiles.nix/blob/a1ef2d1402c9c607e7a3e4427ce125d0cabeddcd/lib/shared/scripts/export-video-list.nix#L12-L31">a small Bash script for my personal laptop</a>.</p>

      <p>I store an archive of video files on an external hard drive of conference talks, courses, tutorials or live streams that I want to keep or rewatch, and found that I've sometimes downloaded the same videos more than once, with the same files on my laptop and hard drive.</p>

      <p>A few days ago, I was watching a video that I thought I'd save, but wasn't sure if I already had, so this script dumps the contents of my hard drive into a JSON file that I can easily browse or search through to see if I already have a video archived.</p>

      <p>The script is fairly simple and uses <code>tree</code> and <code>jq</code> to display and format the data before saving it to a file on my laptop.</p>

      <p>When I need to update the file, I plug in the hard drive and run it again.</p>

      <p>A simple problem, and not something related to a particular project, but something I was able to solve with a Bash script.</p>
