Google Drive sync with rclone

sinc_gdrive.sh

#!/bin/bash

# script to sync Google Drive with local folder using rclone
# modified from initial version that used rsync and a usb disk
# by default will write log to home directory with name sinc_gdrive_log.txt
# check also exclusion list
# usage:
#
# $ sinc_gdrive.sh [command]
#
# command:
# PUSH to push changes to cloud (from local to Google Drive)
# PULL to pull changes from cloud (from Google Drive to local)
# no command runs the script in dry-run mode to preview changes in both directions
