+# List The Installed Version Of A Specific Package
+
+`pnpm` is a Node-ecosystem package manager with first-class support for
+monorepos. In a monorepo with many apps and packages that each have their own
+`package.json` file, it can be tricky to know what version of a package is
+installed for a specific app or package.
+
+The `pnpm list` command can help with that. First navigate to a specific app or
+package whose dependencies you want to know about. Then run a command like the
+following, replacing `@trpc/next` with your package of interest.
+
+```bash
+$ pnpm list '@trpc/next'
+Legend: production dependency, optional only, dev only
+
+epic-react /Users/jbranchaud/code/clients/egghead/products/apps/epic-react
+
+dependencies:
+@trpc/next 10.7.0
+```
+
+It tells you the exact version of that dependency that is isntalled for the
+current app/package.
+
+This command can also be used with regex. Let's say you want to know about all
+`next`-related dependencies. You could do the following:
+
+```bash
+$ pnpm list '*next*'
+```
