How To Create Directories With Mkdir Command.
This tutorial explain how to use the mkdir command.
mkdir Command Syntax:
The syntax for the mkdir command is as follows:
mkdir [OPTION] [DIRECTORY]
The command takes one or more directory names as its arguments.
How to Create a New Directory
To create a directory in Linux, pass the directory’s name as the argument to the mkdir command. For example, to create a new directory newdir, you would run the following command:
mkdir newdir
You can verify that the directory was created by listing the contents using the ls command :
ls -l
drwxr-xr-x 2 root root 4096 Jun 21 13:08 newdirWhen providing only the directory name, without the full path, it is created in the current working directory.
The current working directory is the directory from which you are running the commands. To change the current working directory, use the cd command.
To create a new directory in another location, you’ll need to provide the parent directory’s absolute or relative file path. For example, to create a new directory in the /tmp directory you would type:
mkdir /tmp/newdir
If you try to create a directory in a parent directory where the user does not have sufficient permissions, you will receive Permission denied error:
mkdir /root/newdir
mkdir: cannot create directory '/root/newdir': Permission denied
The -v (–verbose) option tells mkdir to print a message for each created directory.
How to Create Parent Directories
A parent directory is a directory that is above another directory in the directory tree. To create parent directories, use the -p option.
Let’s say you want to create a directory /home/nexonhost/Music/Rock/Gothic:
mkdir /home/nexonhost/Music/Rock/Gothic
If any of the parent directories don’t exist, you will get an error as shown below:
mkdir: cannot create directory '/home/nexonhost/Music/Rock/Gothic': No such file or directory
Instead of creating the missing parent directories one by one, invoke the mkdir command with the -p option:
mkdir -p /home/nexonhost/Music/Rock/Gothic
When the -p option is used, the command creates the directory only if it doesn’t exist.
If you try to create a directory that already exists and the -p option is not provided, mkdir will print File exists error:
mkdir newdir
mkdir: cannot create directory 'newdir': File exists
How to Set Permissions when Creating a Directory
To create a directory with specific permissions, invoke the mkdir commanf with the -m (-mode) option. The syntax for assigning permissions is the same as with the chmod command.
In the following example, we’re creating a new directory with 700 permissions, which means that only the user who created the directory will be able to access it:
mkdir -m 700 newdir
When the -m option is not used, the newly created directories usually have either 775 or 755 permissions, depending on the umask value.
How to Create Multiple Directories
To create multiple directories, specify the directories’ names as the command arguments, separated by space:
mkdir dir1 dir2 dir3
The mkdir command also allows you to create a complex directory tree with one command:
mkdir -p Music/{Jazz/Blues,Folk,Disco,Rock/{Gothic,Punk,Progressive},Classical/Baroque/Early}The command above creates the following directory tree :
Music/
|-- Classical
| `-- Baroque
| `-- Early
|-- Disco
|-- Folk
|-- Jazz
| `-- Blues
`-- Rock
|-- Gothic
|-- Progressive
`-- Punk
Conclusion
The mkdir command in Linux is used to create new directories.
