#add to your .bash_profile / .bashrc

adbd () {
	adb -s $(get_device) "$@"
}

function get_device() {
	local devices=$(adb devices | grep device$)
	if [ $(wc -l <<< "$devices") -eq 1 ]; then
		awk {'print $1'} <<< "$devices" 
	else
		IFS=$'\n' devices=($devices)
		unset IFS
		local device
		PS3="Select a device # "
		select device in "${devices[@]}"; do
			if [ -n "$device" ]; then
				awk {'print $1'} <<< "$device"
			fi
			break
		done
	fi
}

function logcat(){
	local device
	device=$(get_device)
	if [ -z "$1" ]
	then
		adb -s $device logcat | coloredlogcat.py
   	else
      		local filters=""
      		for f in $@
      		do
			export filters="$filters $f:*"
      		done
      		echo "filters $filters"
		adb -s $device logcat $filters *:S | coloredlogcat.py    
  	 fi
}

These functions assume the following are in your $PATH

• adb
• coloredlogcat - https://gist.github.com/schwiz/5178351#file-coloredlogcat-py

When you have more than once device or emulator connected it will offer a menu to select when device to use with adb.

#Usage:

Invoke adb

adbd <command>

Invoke colored logcat

logcat <fliter1> <fliter2> <more filters>

save device-id to variable

deviceid=$(get_device)
