+# Search For Gem Versions Available To Install
+
+The [`gem list`](https://guides.rubygems.org/command-reference/#gem-list)
+command combined with a few flags will produce a listing of all available
+versions of that gem like so:
+
+```bash
+gem list rails --exact --remote --all
+
+*** REMOTE GEMS ***
+
+rails (7.1.0, 7.0.8, 7.0.7.2, 7.0.7.1, 7.0.7, ...)
+```
+
+I can then apply a bit of command-line transformation with `sed` and `tr` to
+turn that list of version numbers into a list that can be nicely consumed by
+other commands. In particular, I will pipe that list to `fzf` so that I can
+fuzzy-search through the huge list for specific version matches.
+
+```bash
+$ gem list rails --exact --remote --all \
+  | sed -n 's/.*(\([^)]*\)).*/\1/p' \
+  | tr ',' '\n' \
+  | sed 's/^ //' \
+  | fzf
+```
+
+The first `sed` command captures everything inside the parentheses. The `tr`
+command replaces the commas with new lines. And the second `sed` command
+removes those leading space on each line.
+
+Lastly, [`fzf`](https://github.com/junegunn/fzf) provides a fuzzy-search
+interface over the list of versions.
