Wrapper script for adb commands (and pidcat!) that take a -s device serial argument, allowing to choose between devices

choose_device.sh

#!/bin/bash
# Prompts for device to use from adb devices -l first; inserts -s parameter.
# No sanitizing, error checking or warranties!
# Use like 
#   $choose_device adb shell

DEVICES=`adb devices -l | sed 1d`

PS3="Choose device or Ctrl+C to quit: "

IFS=$'\n'
select DEVICE in $DEVICES;
do
    unset IFS
    read -r DEVICE_ID _ <<< "$DEVICE"
    ADB_CMD="$1"
    shift
    eval "$ADB_CMD -s $DEVICE_ID $@" 
    break
