# Install and upgrade
> Install the MotherDuck CLI on macOS, Linux, or Windows, keep it current with motherduck upgrade, and control where it stores its files.
## Quick install

### macOS

```bash
curl -s https://install.motherduck.com | SKIP_DUCKDB_CLI=1 sh
```

Runs on Apple silicon (aarch64) and Intel (x86_64).

### Linux

```bash
curl -s https://install.motherduck.com | SKIP_DUCKDB_CLI=1 sh
```

Runs on aarch64 and x86_64, and needs glibc. Only glibc builds are published,
so musl-based distributions such as Alpine stop with an error rather than a
failed exec. 32-bit hosts do the same.

### Windows

```powershell
powershell -c "$env:SKIP_DUCKDB_CLI=1; irm https://install.motherduck.com | iex"
```

Runs on aarch64 and x86_64. Where PowerShell's execution policy blocks this,
see [Windows without PowerShell](#windows-without-powershell).

The installer downloads the build for your platform, installs it under
`~/.motherduck/`, and puts it on your `PATH`.

Open a new shell so the `PATH` change applies, then check the install:

```bash
motherduck --version
```

:::note
The MotherDuck CLI bundles the DuckDB library. The minimal version of DuckDB bundled is the supported DuckDB version.
:::

## Windows without PowerShell

On hosts where PowerShell's execution policy blocks the quick install,
`install.bat` installs the DuckDB CLI only, then points at the PowerShell
installer for the MotherDuck CLI:

```bat
curl -sfL -o install.bat https://install.motherduck.com/install.bat && install.bat
```

It can't detect ARM64 or install the MotherDuck CLI, so use the PowerShell
script wherever you can.

## Upgrade

```bash
motherduck upgrade
```

Replaces the MotherDuck CLI binary on your `PATH`. It does not upgrade the
DuckDB CLI in `~/.duckdb/`, which has its own version: update that through
[DuckDB's own installation](/getting-started/interfaces/connect-query-from-duckdb-cli.mdx#installation).
On a CLI that's already current, `upgrade` says so rather than downloading
again.
