How to Create a Directory in Linux

You can create a directory or folder with different ways in Linux. There are many types of Linux directories, for example, some directories for only Kernel uses, the user uses and some operating system directories. We use directories or folders for storing data or files with specific locations for future uses.

In this article, you will learn about creating a directory in Linux using Commands and as well as a graphical user interface.

How to create a directory in Linux Command

Linux Kernel is open source and Linux provides a lot of commands for interacting with operating system. The Linux also provides a “ mkdir ” command for creating a folder or directory in the Linux. The syntax for creating a directory in Linux is given below:  

• First, open the terminal. Shortcut key ( Ctrl + Alt + T ).
• Using “ cd ” command go where you want to create a directory. You also check the present directory with “ pwd ” command.
• Now write the “ mkdir ” command with the name of the directory.

$ mkdir mydirectory

“ mydirectory ” is the name of your newly-created directory.

With “ mkdir ” command in the Linux, you can use “ mkdir ” command for multiple uses as an example, create a subdirectory in existing folder or directory.

Create a subdirectory

Let’s play with “ mkdir ” command a create multiple folders at the same time with a single command.

                                $ mkdir directory1 directory2 directory3

Now you check the newly directories or folders with the Linux basic command “ ls ”.

The uses of mkdir with different scenarios

Let’s discuss in detail about the “ mkdir ” command with different options and also fast techniques for its working.

mkdir –p option:

If you want to create a directory for complete detail with parents, again parents, and again parent then the syntax is given below:

mkdir – p parents/sun/child

mkdir—m777 option:

We know that the Linux is secure operating system. If you are creating a folder you can set its directories permissions for your new directory. “ –m777 ” option give us complete permission on the new directory for reading data from that folder, writing data in that folder and also execution for everyone. Also 775, 700 etc for different user accesses

Example

                               mkdir—m777 mydirectory

mkdir –v option:

“ –v ” is also an important option with “ mkdir ” command but it also works similar to default. But systex is different:

                                mkdir –v myDirectory

How to create a directory in Linux using java

Java is high-level language but JVM provides a better and fast to interact with basic level of Linux. A simple code for creating a new directory in Linux using java is:

                new File ( ‘ yourNewDirectory ‘ ).mkdirs( );

File myDirectory = new File ( ‘ new folder ‘ ) ;

// this code first chechk the availability of directory that name is wirting in command above.

if ( !myDirectory.exists( ) ) {

System.out.println ( ‘ creating directory:  ‘ + myDirectory.getName());

                               boolean result = false;

                try{

                               myDirectory.mkdir( );

                               result = true;

                }             

                Catch ( SecurityException se ) {

                //handle it

                }       

                If ( result ) {   

                               System.out.println ( ‘ DIR created ‘ ) ;

}

}
