How can I adb install an apk to multiple connected devices?

Question

I have 7 devices plugged into my development machine.

Normally I do adb install and can install to just a single device.

I liked workingMatt's script but thought it could be improved a bit, here's my modified version:

#!/bin/bash

install_to_device(){
local prettyName=$(adb -s $1 shell getprop ro.product.model)
echo "Starting Installatroning on $prettyName"
for APKLIST in $(find . -name "*.apk" -not -name "*unaligned*");
  do
  echo "Installatroning $APKLIST on $prettyName"
  adb -s $1 install -r $APKLIST
  adb -s $1 shell am start -n com.foo.barr/.FirstActivity;
  adb -s $1 shell input keyevent KEYCODE_WAKEUP
  done
  echo "Finished Installatroning on $prettyName"
}

echo "Installatron"
gradlew assembleProdDebug

for SERIAL in $(adb devices | tail -n +2 | cut -sf 1);
do 
  install_to_device $SERIAL&
done

My version does the same thing except:

• it finds the apks from the root of the project
• it installs to every device simultaneously
• it excludes the "unaligned" versions of the apks (these were just being installed over by the aligned versions anyway
• it shows the readable names for the phones instead if their device ids

There's a few ways it could still be improved but I'm quite happy with it.
