Command line Arduino compiling and uploading?

How do I compile and upload Arduino sketches from the command line on Mac and Linux? I've installed the Arduino programming environment. Are there some sample makefiles anywhere?

What is CLI () in Arduino?

Arduino CLI is a command line tool that contains all you need to easily build applications around the Arduino ecosystem. Parse the JSON output of the CLI or implement it as an always-on service that accepts commands via a gRPC interface using your language of choice.

How do I compile an Arduino program?

There are two ways to compile code using the Arduino IDE. You can click the tick-mark button at the top-left. That will begin the compilation. The compilation progress will be shown at the bottom of the screen.

There is a command-line Arduino toolkit named Ino. It just does that.

Compiling and uploading sketches (as apposed to C/C++ sources) on the command line (on Windows, Mac, and Linux) is supported directly via flags to the arduino executable since 1.5.0.

An ino can be compiled and uploaded with arduino --upload [sketch.ino]
