Overview

7-zip doesn't preserve the Linux/Unix owner/group of files and possibly other details. Use tar instead because it's designed to preserve these things, then just 7zip the tar archive.

Create the archive

tar cf - --exclude=\*.o -v directory | 7z a -si -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on directory.tar.7z

Setup a Headless Virtual Machine on Windows using Oracle VirtualBox

If you are concerned with having many windows open when running several virtual machines on your Windows server or workstation, then have them run headless using VirtualBox commandline tools. Additionally, you can manage these VM's using RDP (Mircrosoft Terminal Server Connection - mstsc.exe) or SSH access (if enabled)

Install VirtualBox and Extension Packs

• Download the latest version and install of [Oracle VirtualBox] [vbox]
• Download the [VirtualBox Extension Pack] [vbox] and install for the same version

#!/usr/bin/env ksh
# Testcase runs in ksh93t or greater. Tests should run in any shell provided
# you can supply all the necessary workarounds, and they correctly interpret
# ksh93 printf %q output (requires $'...'). At least one level of recursive
# arithmetic variable evaluation must also be supported.
# Dan Douglas <ormaaj@gmail.com>

namespace main {
	# e.g. add "set -x" to hacks
	typeset -A shells=(
