Command line Arduino compiling and uploading?

Question

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 an

I use platformio, quite like it. It also has extensions into Visual Studio Code, so you can do everything from there. It has library manager and uploader built-in.

My setup is a NFS drive where I have the code, mounted on my linux laptop, and also mounted on my Raspberry Pi that sits next to my Arduino's.

When it's time to compile, I do so on my laptop, and as the RPi is next to the Arduino, I upload from there..

After installing and configuring, the basics are simple; 'platformio run' will compile your code. 'platformio run -t upload' will compile & upload.

I also have a bash function to upload without compiling;

function th(){
    if [ "${1}" = "upload" ];then
    if [ ! -f platformio.ini ]; then
        echo platformio.ini not found
    else 
        UPLOAD_PORT=`cat platformio.ini | grep upload_port | awk '{print $3}'`
        if [ "${UPLOAD_PORT}" = "" ]; then
            echo no upload port
        else
            if [ "${2}" != "" ]; then
                FIRMWARE=${2}
            else
#the firmware location seems to have moved
#               FIRMWARE='.pioenvs/megaatmega2560/firmware.hex'
                FIRMWARE='.pio/build/megaatmega2560/firmware.hex'
            fi
            if [ -f "${FIRMWARE}" ]; then
                avrdude -v -p atmega2560 -C /home/stevenk/.platformio/packages/tool-avrdude/avrdude.conf -c wiring -b 115200 -D -P "${UPLOAD_PORT}" -U flash:w:$FIRMWARE:i
            else
                echo ${FIRMWARE} not found
            fi
        fi
    fi
    else 
            wget --timeout 8 -qO- http://192.168.178.212/$1
    fi
