# 18 — Path expansion (`~`, `*`, `**`)

**Status:** done
**Related:** #13 shell globbing

Path expansion for `~` is not available. Commands like:

```
!cat ~/Notes/jobs_board.md
```

fail with:

```
cat: ~/Notes/jobs_board.md: No such file or directory
```

The `~` and other expansions are passed literally to the command rather than being expanded to `$HOME`.

## Requirements

- `~` at the start of a word should expand to `$HOME`
- Should work in both backtick and `!` prefix contexts

### To invesitigate/decide

- How should it interact with quoting (quoted `~` should not expand), should single/double quotes be used? both? or something else?
