How to use the Window command line (DOS)
How to use the Windows command line (DOS).
This document covers the basic in navigating and using the Microsoft Windows command line. On this page, you'll learn how to move around in the command line, find files, manipulate files, and other important commands. Keep in mind that there are well over 100 different commands that have been used in MS-DOS and the Windows command line. If you're interested in learning every command, see our Microsoft DOS and command prompt help page, which gives a description and example about each of these commands.
Get into the Windows command line
Open a Windows command line window by following the below steps. If you need additional information or alternative methods for all versions of Windows, see our how to get into DOS and Windows command line page.
- Click Start
- In the Search or Run line type cmd and press enter.
Understanding the prompt
After following the above steps, the below black box will open, this is the Windows command line. By default Windows will take you to your users directory. In the below example, the user is Mrhope, so we're in the C:\Users\Mrhope directory and our prompt is C:\Users\Windows>. From this prompt information we know we're in the C: drive (the default drive letter of the hard drive) and currently in the Mrhope directory, which is a subdirectory of the Users directory.
- MS-DOS and the Windows command line are not case sensitive.
- The files and directories shown in Windows are also found in the command line.
- When working with a file or directory with a space, surround it in quotes. For example, My Documents would be "My Documents".
- Filenames can have a long file name of 255 characters and a 3 character file extension.
- When a file or directory is deleted in the command line, it is not moved into the Recycle bin.
- If you need help with any of command type /? after the command. For example, dir /? would give the options available for the dir command.
Listing the files
Lets learn your first command. Type dir at the prompt to list files in the current directory. You should get an output similar to the below image example. By default, without using any dir options this is how dir output will appear. As can be seen, you're given a lot of useful information, the modification or creation date and time, an indication if the listed item is a directory (<DIR>), and the actual name of the directory or file. In the below example, there are 0 files listed and 14 directories as indicated by the status at the bottom of the output.
Every command in the command line has options, which are additional switches and commands that can be added after the command. For example, with the dir command you can type dir /p to list the files and directories in the current directory one page at a time. This switch is useful to see all the files and directories in a directory that has dozens or hundreds of files. Each of the options and switches for each command is listed on our DOS command page. For example, if you want to see all the options for dir see our dir command page for a full listing.
In addition to switches, the dir command can also be used to search for specific files and directories by using wildcards. For example, if you only wanted to list files or directories that begin with the letter A you could type dir a* to list only the AppData directory, in this above example. See the wildcard definition for several other examples and help with using wildcards.
Moving into a directory
Now that we've seen a list of directories (shown above) available in the current directory lets move into one of those directories. To move into a directory, we use the cd command, so to move into the Desktop type cd desktop and press enter. Once you've moved into a new directory the prompt should change, so in our example, the prompt is now C:\Users\Mrhope\Desktop>. Now in this directory lets see what files are found in this directory by typing the dir command again.
Understand the files
Now in the Desktop directory in this example (as shown above), we now have 23 files and 7 directories. As can be seen in the above example, there are several different file types. In Windows, you're familiar with files having icons that help represent the type of files. In the command line, the same thing is accomplished by the file extensions. For example, "forum posts.txt" is a text file because it has a .txt file extension, Time.mp3 is a MP3 music file, and minecraft.exe is an executable file.
For most users, you'll only be concerned with executable files, which as mentioned above is a file that ends with .exe and are also files that end with .com and .bat. When the name of these files is typed the program will run. This would be the same thing as double-clicking a file in Windows to open the program. For example, if we wanted to run minecraft.exe typing minecraft at the prompt will run that program. Keep in mind though that if the executable file you're trying to run is not in the current directory you'll get an error.
If you wish to view the contents of a file, most versions of the command line use the edit command. For example, if we wanted to look at the log file hijackthis.log we would type edit hijackthis.log at the prompt. For 64-bit versions of Windows that do not support this command you can use the start command, for example, type start notepad hijackthis.log to open the file in Notepad.
Moving back a directory
You learned earlier the cd command can move into a directory. This command also allows you to go back a directory by typing cd.. at the prompt. When this command is typed you'll be moved out of the Desktop directory and back into the user directory. If you wanted to move back to the root directory typing cd\ takes you to the C:\> prompt. If you know the name of the directory you wish to move into, you can also type cd\ and the directory name. For example, to move into C:\Windows> you would type cd\windows at the prompt.
Creating a directory
Now with your basic understanding of navigating the command line lets start creating. To create a directory in the current directory use the mkdir command. For example, lets create a directory called test by typing mkdir test at the prompt. If created successfully you should be returned to the prompt with no error message. After the directory has been created, move into that directory with the cd command.
Creating a new batch file
Now in the newly created test directory lets create your fist file. In most situations, you will never need to create any file at the command line, however, it's still good to understand how files are created. In this example, we will be creating a batch file. A batch file is a file that ends with .bat and is a file that can help automate frequently used commands in the command line. We will be calling this batch file example, so type edit example.bat at the prompt. As mentioned earlier if the edit command doesn't work use the start command to open the batch file in notepad, so you type start notepad example.bat at the prompt.
Either of these commands will open a new blank window for the example.bat file. In the blank file, type the below three lines, which will clear the screen with the cls command and then run the dir command.
After these three lines have been typed into the file save and exit the file. If you're in the edit command Click File (or press Alt+F) and then Save. After the file has been saved and you're back into the command prompt, typing dir should display the example.bat in the test directory.
Now run the batch file to get a better understanding of what a batch file does. To run the batch file type example at the prompt. This will execute the batch file causing it to clear the screen and then do the dir command and display the directory listing of the test directory.
Moving and copying a file
Now that we've created a file lets move it into an alternate directory. To help make things easier lets create another directory to move the file into. So, type mkdir dir2 to create a new directory in the test directory called dir2. After the new directory has been created, use the move command to move the example.bat file into that directory type move example.bat dir2 which should return a message indicating that one file was moved. You could also substitute the move command for the copy command to copy the file instead of moving it.
Rename a file
After the file has been moved into the dir2 directory lets move into that directory with the cd command so we can rename the file. In the dir2 directory lets use the rename command to rename the example file into an alternate name. Type rename example.bat first.bat at the prompt to rename the file to first.bat. Now when using the dir command you should see the first.bat as the only file.
Tip: When renaming any file make sure the file has the same file extension. If you were to rename a .bat file to a .txt file, it is no longer an executable file only a text file. Also, keep in mind that renaming the file to a different file extension does not convert the file. For example, if you were to name the file to a .MP3 file it may look like a MP3 audio file in Windows, but it is not going to play music.
Deleting a file
Now that we've had our fun with our new file lets delete the file with the del command. Type del first.bat to delete the first.bat file. If successful, you will be returned to the prompt with no errors and the dir command will show no files in the current directory.
Tip: When deleting files you can also use wildcards to delete multiple files at once. For example, if the directory contained several .GIF image files you could type del *.gif to delete all files ending with the .gif file extension.
Renaming a directory
Lets go back one directory to get back into the test directory by using the cd.. command mentioned earlier. Lets now rename our del2 directory to something else using the same rename command we used earlier. At the prompt, type rename dir2 hope to rename the directory to hope. After this command has been completed, type dir and you should now see one directory called hope.
Removing a directory
Still in the test directory lets now remove the hope directory by using the rmdir command. At the prompt, type rmdir hope to remove the hope directory.
Tip: If the directory you're trying to remove contains any files or directories, you'll receive an error. To prevent this error use the /s option. For example, if the hope directory still had the first.bat file you would need to type rmdir /s hope at the prompt.
Following all of the above sections you should now have a good understanding on how to navigate in the command line, create directories and files, rename files and directories, and delete files and directories. As mentioned earlier, there are hundreds of other commands that can be used at the command line. If you want to expand your knowledge even more, we highly recommend looking at the options available for each of the above commands and go through our commands overview.
