+# Restart Specific Overmind Process
+
+I have been in the bad habit of fully killing and re-running the entire
+`overmind` process for a project whenever I have a new JavaScript file that I
+need `vite` to pick up and bundle. `vite` is only one of three processes, so I'm
+restarting two processes unnecessarily.
+
+```bash
+❯ overmind status
+PROCESS   PID       STATUS
+web       50897     running
+vite      50898     running
+worker    50899     running
+```
+
+Instead, what I can do is specifically target the `vite` process for a
+`restart`.
+
+```bash
+❯ overmind restart vite
+```
+
+This will restart that specific process, ensuring that the new JS files get
+picked up and bundled.
+
+I can clearly see that only `vite` was restarted by looking at the `status`
+subcommand again.
+
+```bash
+❯ overmind status
+PROCESS   PID       STATUS
+web       50897     running
+vite      84163     running
+worker    50899     running
+```
+
+Notice the `web` and `worker` processes still have the same PIDs, but `vite` has
+a new much higher PID.
+
+See `overmind restart --help` for more details.
