As we know that command prompt is a non-graphical interface that allows user to directly interact with operating system. With the help of Commands, a user can solve (troubleshoot) many OS related problems. Today, mostly peoples using OS based on GUI (Graphical User Interface) as it is best way for end users to understand (run) computer and to interact with computer. But, they can’t do anything with help of GUI as commands are still the heart of the OS, which are mainly running at the core level of the OS. To perform chief tasks directly with OS, all they need is to learn commands. Commands are the main stage designed for professional (advanced) users. So, here on this page, I am representing some useful important commands based on Windows Operating System. In order to access Command Prompt in Windows Operating System, from the Start menu, select Run and enter- ‘cmd’. After this, press ‘enter’ button or click on ‘OK’ button. You are now ready to run any commands to perform any OS related operation.
Some Useful Important Commands are as follows: 1. In order to see files in a directory or folder then, you need is to type “dir” command and press enter to get result.
2. To go to another partition from the current location as C:\Documents and Settings\Bhavesh then, just type “cd ..” command and press enter in order to leave that location. Type the partition name like partition G and colon as “G:” and press enter in order to enter that partition. In this way, you can enter in other partition.
3. To enter one folder to another, use “cd” command and to leave that folder, use “cd ..” command. For example, to enter in a folder of G partition as type “cd” and the name of the folder. Here, we can see that G drive has folder named “Newspaper address”. To Enter in “Newspaper address” folder, the command format will be : cd Newspaper address
4. To see all the services running under each process of a computer then, use the following commands as-
“tasklist /svc” and “tasklist /s” 5. “Systeminfo” command is used to show the complete system information of a computer.
