Answer 1

You are asking a forum member to provide you a full course on a couple of different areas of computer usage. This is not a simple topic where one could give a short example or illustration in answer to your question, but would rather require a entire class on the subject.

Now, all I can do is give you some decription of what these computer topics are, but I can't explain or teach you how to use them, or implement them, here an Answers. Too long and complicated for that.

Now, cmd.exe is the Command Prompt, and it runs as a DOS application. At one time the only way to run anything on a computer was via DOS, and the Command Prompt was the official portal into that system. Once, your entire screen was black, and only contained a blinking curser where you inputed data.

As systems evolved the GUI--Graphical User Interface, was created, which is how the desktop came about and programs where able to be seen in pretty colors and in Windows on the desktop. The Command Promt became a component, rather than the main feature, and is actually becoming less important except for programmer, debuggers, IT professionals, Help Desk personnel, ect.

You can execute many different commands witht the command prompt. You can run batch jobs, which are small code files that perform certain tasks, and are created by writing code into a file. You can use the Windows Notepad to create a batch job, and then run it with the command prompt, or schedule it via the Task Schedular, or write a logon/logoff script to perform certain functions at logoff or logon. This is usually done in corperations which have certain needs a home user wouldn't.

Now, regarding your question of whether or not you can use the command prompt to hack into anything, that I don't think you can do. Now, if you put your laptops hard drive as slave in your desktop, you could then access the files on the laptop via the command prompt. You would need to know how to use command prompt to browse to different directories, or you wouldn't be able to access those files.

However, there are much easier methods of accessing files on one computer from another. Simply use your network connection and access the files in that method. Much easier and simpler, than trying to use command prompt to do so.

The command prompt was once taught in every Introduction to Micro Computers class. Everyone knew how to use it. Now, it is seldom discussed unless an individual accesses course work which impliments the command prompt.

This move away from the command promt in normal home usage has created a situation in which many individuals have little or no understanding of what the command prompt is, how it works, and where it is useful in computer usages. Which is why you are only now discovering it on your own.

Now, you can access information on command prompt in Help and Support. Simply open Help and Support, and enter Command Prompt into the Search box, and click Search. Then click on the different links to information and begin teaching yourself how to use it. It is more difficult to teach yourself than to have an instructor lead the way in the learning cycle, but it is better than nothing. The command prompt does have a great deal of power and uses.

The first thing you will need to learn is how to browse different directories on your system. A "directory" is simply a folder or area of your hard drive, such as drive C, or D, and/or any folder or executable file in those folders.

To run a script, you browse to the directory where the script resides, then type in the script name and hit Enter, and the script runs from where it is located on your hard drive.

When you first open command prompt you are located in your profile folder, such as:

C:\Documents and Settings\YourUserName>_

The "_" is the cursor and it flashes.

To change the directory from your profile, simply type in cd (change directory) and follow that with the path to the directory you wish to browse to, such as

cd C:\

When you do this, the command prompt changes to:

C:\>_

Again, the "_" is the cursor and it flashes to show where you are currently.

With the Change Directory command you can begin practicing how to move around in command promt and from there learn how to use other commands.

Now, command prompt has many other functions than managing your directories, (directories are simply all of your folders on your system) it also launches programs, enter commands to manage different components on your system such as your hard drive maintence, (deleting and creating partions, etc) run scripts, from the most simple to the most complex, even hook into other systems if your computer is properly configured for this, and it usualy takes a Server to do so. It is very powerful and complex, so be very careful.

*Note* When you delete something from the command prompt it bypasses the Recycle Bin, and does not give any warning notice. It is immediantly deleted and you are not notified of that fact. It would be irretrevible, lost for good, so be very careful while playing with command prompt.

Hope thishelps you some, do use the Help and Support applet to locate further information on commands and the syntax used. Good luck and a very happy holiday season.

Answer 2

If you get in there and type help
You'll get a list of most commands.
If you type help followed by the name of any of those commands, you'll get info on the possible parameters of that command.
You can get a handy little reference to commands in the cited text.
(I'm the old fashioned sort...I use cmd.exe rather often!)

Answer 3

It is not much use as a hacking tool, it allows access to certain programs without having a Windows GUI running. To connect to another machine from it, you need to run a telnet server, and open it's port in the firewall on the remote machine. Since telnet is a dangerously insecure protocol, this is not a clever idea. No serious network ever allows telnet now.

Answer 4

just type dir
