Examples of the Unix mkdir command

Linux directory FAQ: How do I create (make) a directory on Linux or Unix?

The Unix/Linux mkdir command is used to create new Unix/Linux directories (sub-directories). Let's take a look at some mkdir command examples.

How to create one directory

This first example creates a new directory named tmp in your current directory:

mkdir tmp

This example assumes that you have the proper permissions to create a new sub-directory in your current working directory.

Linux mkdir example - How to create multiple directories at one time

This command creates three new sub-directories (memos, letters, and e-mail) in the current directory:

mkdir memos letters e-mail

Linux mkdir example - How to create several subdirectories at one time

Use the -p option of the mkdir command to create multiple levels of subdirectories with one command. This example creates the directory /home/joe/customer/acme/foo/bar, and makes all intermediate subdirectories, as needed:

mkdir -p /home/joe/customer/acme/foo/bar

As you can imagine, that's a lot easier than typing these equivalent commands:

cd /home/joe
mkdir customer

cd customer
mkdir acme

cd acme
mkdir foo

cd foo
mkdir bar

Linux mkdir command: "Permission denied" errors

As a final note, if you try to create a directory like this:

mkdir baz

and you get an error message like this:

mkdir: cannot create directory 'baz': Permission denied

as the message implies, you don't have permission to create this directory. You can use the ls command to figure out what permission you have in this directory.



Hi, what does "touch var/.htaccess | mkdir app/etc" do?

In this case, the file .htaccess doesn't exist, so it will be created with the touch command, but then what happens when redirected to the mkdir command?

Thanks for your help!

The 'touch' command will do what you say, creating a file if it doesn't exist, or updating the timestamp on the file if it does exist.

The "|" symbol there seems incorrect, perhaps it is two pipes, i.e., "||"? If so, that's an "OR" symbol, and then that command makes a little more sense ("do this or do that").
