Cygwin Overview

Cygwin offers a UNIX like environment on top of MS-Windows. You can use UNIX/LINUX utilities & programs

(gcc, vi, emacs grep, …) under MS-Windows UNIX programs can be ported to cygwin and run

under MS-Windows OS. assist developers in migrating applications from

UNIX/LINUX to the Microsoft Windows platform Does not require a UNIX administrator’s level of

expertise to setup and maintain.

Cygwin Snapshot

Cygwin Description

Cygwin consists of a library that implements the POSIX system

call API in terms of Win32 system calls a GNU development toolchain (such as gcc

and gdb) to allow software development a large number of application programs

equivalent to those on the Unix system

Cygwin Features

Command line tools: Compiler (gcc, g77, g++, make) Network tools (ssh, scp, rsync) Programming tools (splint, indent) Version control system (cvs, rcs) File tools (diff / patch, head / tail / cut,

od) Shell scripting (bash, tcsh, zsh) Archive (tar, gzip, bzip) Man Pages Interpreters (expect, Tcl/Tk, perl,

python) Editors (vi, pico (see pine), emacs) Easy copy / paste between cygwin

and MS-Windows programs (rxvt) Scheduled task capability (cron) {Extension: ImageMagick (convert)} {Extension: CD Images (mkisofs)}

GUI based tools: Xemacs “xv” Ghostscript {Extension: GrADS}

Virtual Machine(VM) - Overview

Software implementation of machine (computer) that executes programs like a real machine System VM

provides a complete system platform ex) VMware workstation Advantage of system VM

Multiple OS environments can co-exist on the sma emachine in strong isolation from each other

VM can provide an instruction set architecture (ISA) that is somewhat different from that of the real machine

Process virtual machine Is designed to run a single program, supports single program Provide platform independent programming environment. ex) JAVA

VM. JAVA bytecode. “write once, run anywhere” (WORA)

VMware Workstation

successful VM software made by VMware, Inc. VM software for desktop x86-type PC allows users to set up multiple x86 and x86-64 virtual computers Use several virtual computers simultaneously with the hosting OS Each virtual machine instance can execute its own guest OS

(e.g. LINUX, MS-Windows, …) Allows multiple applications to run in isolation within virtual

machines on the same physical machine

Easily speacking, VMware Workstation allows one physical machine to run multiple

operating systems simultaneously

VMware Workstation

LINUX under MS-Windows

VMware Characteristics

Partitioning Run multiple operating systems on one physical machine

Isolation Isolate faults and security at the virtual-machine level Dynamically control CPU, memory, disk and network resources per virtual

machine

Encapsulation Encapsulate the entire state of the virtual machine in hardware-independent files Save the virtual machine state as a snapshot in time Re-use or transfer whole virtual machines with a simple file copy
