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
Advantage of system VM



ex) VMware workstation
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


Isolation



Run multiple operating systems on one physical machine
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
