arduino: Build and upload a sketch.

arduino

$ arduino --upload ${filename-ino}

try on your machine

This command is likely being used to upload an Arduino sketch (code) to an Arduino board. Let's break it down:

arduino is the name of the command being executed.
--upload is an option or argument provided to the arduino command, indicating that we want to upload a sketch.
${filename-ino} is a placeholder for the actual filename (ending with .ino) that you want to upload.

The ${filename-ino} syntax suggests that the command is likely part of a script or a command-line environment where variables can be substituted. In this case, you would replace ${filename-ino} with the actual filename of the Arduino sketch you wish to upload.

Overall, this command is used to initiate the upload process for an Arduino sketch with the provided filename. It will compile the sketch, if necessary, and send the compiled code to the connected Arduino board, replacing any already uploaded sketch.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
