First is : mkfs.ext4 : This part of command will create a new ext4 file system on following device where this command will get executed.

Second is : /dev/sda1 ;This part of command specifies the 1st partition on the first hard disk which is probably in use by the user. Similarly, This Command > mkfs.ext3 /dev/sdb2 will Format the second partition on the second hard disk with ext3 File system.

4. Command > /dev/sda – Write Any content Directly to a Hard Drive.

First of all, you need to open the Run window by just pressing the Windows Key along with the R key, i.e. Windows + R. Now, you have to type the name of the program that you desire to open up or execute. Unfortunately, not all programs can be accessed through this method. So, let me show you how to create Run commands that do not come as inbuilt commands.

STEPS TO CREATE RUN COMMANDS OF YOUR OWN

Step 1. The first step is to select the software or application for which you want to make custom Run command. For example, let us consider Google Chrome as the example here. Remember, you can choose any application other than which is already there in the Run command.

Step 2. In the second step, right click on the desktop of your computer system and make a new shortcut.

Right click > New > Shortcut

Step 3. As you select the Shortcut option in the 2nd Step, it will open up a dialog box. And, the dialog box will ask you path of the application or software for which you want to create the Run command.

Step 4. Now, you need to browse through the files and choose the one that shows “chrome.exe”. Well, it is quite obvious that all the executable files can be found in the C drive (or wherever the Operating System has been installed), inside the folder “Program Files”. For example, “C:\Program Files\Google Chrome\chrome.exe”

Step 5. Once you are done with Step number 4, just click on “Next” button and simply provide a relative name to that shortcut. Remember, the same name will be used later in the Run command.

For example, “GC” for Google Chrome

Step 6. Now, click on the “Finish” button. Once it is done, an icon related to that application or software will show up on your computer’s screen. It means that the process of creating shortcut has been done successfully.

Step 7. In this step, just cut and paste that recently made shortcut icon into your computer’s root drive, in its Windows folder.

For example, C:\ Windows , Make sure you are the administrator of the computer or have its password.

Step 8. Now, you are done with the set up and can run the application through Run Command. Just go to Run and enter the keyword “GC”, and Google Chrome will begin executing.
