The BASH shell prompt is far superior to the so called command prompt in Windows.

The Windows command prompt I have been using quite a bit in a Networking and Databases course I am studying right now is really getting on my nerves. Not being able to press CTRL-L to clear the command prompt window, not being able to copy and paste as easily as you can with the Gnome Terminal, this is really annoying me. The Windows command prompt does have some cool commands, you can list running processes with the tasklist command and then kill an offending process with the tskill command, but it is a poor imitation of the superior BASH or Zsh shells. Even TCSH and CSH are far better than the DOS like environment in Linux. In the BASH shell; you may type ps aux | grep me-tv for example to find a hung process and then use kill -9 3737 to kill that process. The -9 parameter to the kill command makes it kill the process without caring about its feelings at all, it makes every effort to kill that offending process. There is a nice page on the Advanced Bash Scripting Guide that contains a nice guide on converting a DOS batch file into a UNIX/Linux equivalent. This is very helpful when you have found an old batch file and thought it might be useful on Linux.

But the *NIX shells are far superior to any Windows equivalent command shell. The Powershell is supposed to be a good alternative, but it is hard to use unless you learn all of the commands that is; the Powershell was originally named MONAD and is supposed to compensate for the fact that a DOS command prompt is a sad alternative to a Linux shell prompt.  Zsh is an alternative to the BASH shell that has many good features. Amongst them is the ability to create a nice prompt theme. This is mine.

And this code added to the bottom of your ~/.zshrc will create this lovely prompt theme.

The Powershell and DOS prompts do not have this level of customization. If you are using a Macintosh machine; which runs on a variant of the UNIX kernel and has a proper command prompt window available, then you may install Zsh and enjoy a far superior command-line experience than Windows users. This web page: http://seanmmcdaniel.com/2011/09/zsh-on-os-x/, has a good explanation of how to install the Zsh shell on an Apple Macintosh machine. Windows users like to dump on the Apple users, but the fact is that Windows gets far more viruses than the Apple Macintosh and Linux platforms. Even Steve Ballmer uses an Apple Macintosh laptop whilst vowing to fscking kill Google! That is hilarious, he prefers a stable and reliable UNIX based operating system instead of Windows. Apple uses the Darwin UNIX operating system to build their successful OSX on top of. This may be downloaded in the form of an ISO image here: http://www.puredarwin.org/downloads the Darwin UNIX operating system is an interesting OS, but I could not get the version I downloaded to boot on my computer. The Darwin UNIX operating system is derived from the old NextStep operating system.

That was an operating system that was the desktop that the Doom developers used to create their levels using a level editor they coded. Nowadays you can use the Linux and Windows platforms to do that kind of work. The NextStep operating system interface is now available as the Windowmaker window manager on Linux and UNIX. Shown below is how to install this.

Here is another cool trick to try in Linux. Type this command to load the Xnest window.

[email protected]:~$ Xnest :1

Then run this command and you may run Xterm in a window on your desktop!

[email protected]:~$ xterm -display :1
