copy dot files from various locations to a single folder for backup.

linkthedots.sh

#!/bin/bash

#script to copy the dotfiles to/from here to/from their proper places
#added file structure preservation - files are copied to their location related to root
#added logging errors

#to clone/sync my dotfiles: git clone https://github.com/arpanpal010/dotfiles.git

#Usage:
#$ sh linkthedots.sh collect --> get files
#$ sh linkthedots.sh push --> put files
#$ sh linkthedots.sh cleanstore --> remove files from dotstorage
#$ sh linkthedots.sh cleanfiles --> remove files from config locations
#$ sh linkthedots.sh help --> show this help
