You are helping the user install or update datafusion-cli.

Arguments: $@

Step 1 — Check if datafusion-cli is already installed

command -v datafusion-cli

If found, check the version:

datafusion-cli --version 2>&1 | head -1

Step 2 — Determine the action

If --update is in the arguments and datafusion-cli is installed → update mode
If datafusion-cli is not installed → install mode
If installed and no --update → report the current version and stop

Step 3 — Install or update

Detect the platform and offer the appropriate method:

macOS

Option 1 — Homebrew (recommended if brew is available):

brew install datafusion

Or for update:

brew upgrade datafusion

Option 2 — cargo install (works on all platforms):

cargo install datafusion-cli

Linux

Option 1 — cargo install (recommended):

cargo install datafusion-cli

Option 2 — Download pre-built binary from GitHub releases:

LATEST=$(curl -fsSL https://api.github.com/repos/apache/datafusion/releases/latest | grep -oP '"tag_name": "\K[^"]+')
curl -fsSL "https://github.com/apache/datafusion/releases/download/${LATEST}/datafusion-cli-${LATEST}-x86_64-unknown-linux-gnu.tar.gz" | tar xz
sudo mv datafusion-cli /usr/local/bin/

All platforms — cargo install

If neither brew nor pre-built binaries are suitable:

cargo install datafusion-cli

For update via cargo:

cargo install datafusion-cli --force

Note: cargo install requires a Rust toolchain. If cargo is not found, suggest installing Rust first via rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Step 4 — Verify

datafusion-cli --version

Report success with the installed version.
