Project on Linux file encryption using GPG

My project to get familiar with Linux Commands and GPG tool for managing file security and Encryption

	#! /usr/bin/env bash
	#Project : To familiarize with Linux Commands
	#Author :-sanath vernekar
	#Procedure to use in Linux Terminal
	#chmod +x file path along with file name
	#ex: chmod +x /home/sanath/linux_commands.sh
	#then directly execute this file by entering ./filename
	#ex:./linux_commands.sh
	#Requires
	#1.uvacapture -----image capturing tool
	#2.libnotify-bin ----notifier
	#3.gpg ------Encryption Tool
