Mention nohup
- This is usually handled by the shell, so it depends on the shell. That said, the relevant command is named the same across many different shells. Namely, the [`disown`](https://en.wikipedia.org/wiki/Disown_(Unix)) command. You can probably enter `help disown` for details relevant for your shell. Most likely it's `bash`, where the details are also described [here](https://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash.html#index-disown). `fish` literally uses the situation you describe as an [example](https://fishshell.com/docs/current/cmds/disown.html). As illustrated there, and this should work for `bash` as well, you would enter something like:
- `firefox &; disown`
Without arguments (for `bash` and `fish` at least), `disown` will disown the most recently used job. More generally, you can pass a PID or jobspec to indicate which background job to disown which you can get from `ps` or, depending on your shell, `jobs` will probably list them.

- There's also the POSIX [`nohup`](https://en.wikipedia.org/wiki/Nohup) command which spawns a process immune to `SIGHUP`, which the shell sends to the jobs it manages when it terminates. In this case, you have to know ahead of time, e.g. you'd enter `nohup firefox &`. That said, this makes the spawned process immune to `SIGHUP` from any source which may not be desirable.
