Shell script to connect a USB connected device via adb over WiFi

adbwificonnect.sh

# Purpose: Shell script to connect a USB connected device via adb over WiFi
#
# Author: Amanshu Raikwar
#
# Assumptions:
#	1. USB debugging is enabled in the Android device
# 	2. The Android device is connected to the computer via USB
# 	3. The Android device is connected to the same wifi as the computer
# 	4. The Android device is accessible through port 5555 over the wifi network
# 
# How To Use (without any options):
# 	1. Paste the file where adb resides, for mac it is ~/Library/Android/sdk/platform-tools/
# 	2. Run ./adbwificonnect
# 	3. Choose the device by typing X in [X] --> ... when prompted
# 	4. Wait around 6-7 seconds
# 	5. Connected!
#
# Options:
#	-a 
#		To connect to all available devices
#
#	-d device_id
#		Sepcifies the device id to be connected to

# if no command line params provided
