# update

> Update gx to the latest version

`gx update` detects how gx was installed and runs the appropriate update command.

## Usage

```bash theme={null}
gx update
```

## Behavior

gx detects the installation method by inspecting the binary's path:

### Homebrew (auto-detected)

If the binary is inside a Homebrew Cellar or Linuxbrew path, gx runs `brew upgrade gx-git` directly:

```bash theme={null}
$ gx update
Current version: 2.0.1
Installed via Homebrew. Updating...

...brew output...

OK Updated via Homebrew. Run `gx --version` to verify.
```

### Other install methods

If gx cannot detect Homebrew, it shows manual instructions:

```
Current version: 2.0.1
> To update, reinstall via your package manager:
  Homebrew: brew upgrade gx-git
  pipx:    pipx upgrade gx-git
  go:      go install github.com/mubbie/gx-cli@latest
```

## Homebrew Detection

gx resolves symlinks on the binary path and checks if it contains `cellar`, `homebrew`, or `linuxbrew` (case-insensitive). This covers standard Homebrew installations on both macOS and Linux.

<Tip>
  If you installed via `go install`, updating is as simple as running the install command again: `go install github.com/mubbie/gx-cli@latest`
