 In more recent releases of Microsoft Windows, there is a "bash shell" environment available, which is a version of Ubuntu Linux. An older solution to the Windows versus Unix question is a system called Cygwin, which comes in 32 bit and 64 bit systems. For Microsoft Windows installations, you will need to also add an X-windows server.Finally, users may configure their windows as dual-boot platforms, enjoying either a completely linux or a completely Microsoft environment.
+More recently in Ubuntu 20.04 and later, the Linux environment for Window is called the Windows Linux Subsystem (WSL) and is an effective environment for installing Linux operating systems. Yet another tool is the Hyper-V virtual machine environment.
 Everything that follows in this discussion is executed on the "Unix command line". To do anything further requires that you

 Note that the first dollar sign merely represents the command line prompt, which may be different on your system. The object  $SHELL is read as "value of" the variable SHELL. Here SHELL is an environment variable, that has the value of /bin/sh, /bin/bash, /bin/ksh, /bin/zsh, /bin/csh, /bin/tcsh and it is customary to write environment variables all in capital letters.
-=== Shell environment:  /bin/bash ===
+=== Shell environment:  /bin/bash  (the Bourne Again Shell) ===
 The most common shell environment these days is /bin/bash and the configuration files in your home directory are .bash and .bash_profle  These files must be edited so that the environment variable CWPROOT and that $CWPROOT/bin are on the users' path.

 The C-Shell is a totally different environment. These are less commonly used environments, today.
