Enhanced partition copy script (new & improved!)
08-23-2010
#! /bin/bash
# Name: partition-copy.sh
# By: Jan Zumwalt - www.neatinfo.com
# Ver: August 22th, 2010
# About: Copies partition and support files using dd command
#
# Copyright:
# 1992-2010 by Jan Zumwalt, www.neatinfo.com
# This software is free and open to the public. You may use, copy,
# modify, distribute, and sell this program (and any variants)
# without restriction, so long as you do not restrict others from
# doing the same.
#
# History:
# 1992 - simple script for IBM AIX and Minix OS @20 lines
# 1995 - enhanced and re-designed for SUSE Linux OS @60 lines
# 1998 - enhanced and re-designed for Mandrake Linux OS @100 lines
# 2002 - log and re-designed for PcLinux OS @150 lines
# 2005 - verbose comments and info section @250 lines
# 2008 - modifiable variables to top, keybrd input, user modifiable @350 lines
# 2009 - error checks, self install and shortcut feature @450 lines
# 2010 - aesthetics, menus and aux system files capability @600 lines
#
# Future enhancements:
# *Calculate file save elapsed time - in beta testing
# Improve log format
# Ability to save session log with partition file
# Restore feature
# Better file compression
# Kill process feature
#
# code remarks:
# -e = enable interpretation of backslash codes
# -n = disable newline at end of line (i.e. user input prompt)
# ${VAR} can be used to separate a variable if no space is
# available in a string, ie "http://www.${WEB}.com"
# exit 1 = error, exit 0 = success
# +------------------------------------------------------+
# | These are the user modifiable variables. The |
# | "MENU" variables are for the partition menu. |
