Creating a directory tree with a one command

The mkdir command can do much more than make a one directory. It can develop multiple directories at when and can even generate an full directory structure with a solitary command. The demanded command will be a tad complex, but not particularly demanding.

Notice: If you attempt to set up a multi-amount directory composition with a command like the a single shown down below, it will never do the job if the first directories (“this” and “that”) will not already exist.

$ mkdir this/that/the_other
mkdir: simply cannot build listing ‘this/that/the_other’: No this sort of file or listing

Add a -p (for “moms and dads”) and the missing directories will be produced and your this/that/the_other listing composition will be established up in your present listing as meant.

$ mkdir -p this/that/the_other
$ ls -l this/that
whole 4
drwxrwxr-x 2 shs shs 4096 Jul 7 10:01 the_other <== all done!

Creating a more complex directory structure

You can also set up a directory structure that has multiple subdirectories at some level. In the following example, four separate directories will be set up within the Documents/personal directory. And, again, given the use of -p, the Documents and Documents/personal directories will first be set up if they don’t already exist.

$ mkdir -p ~/Documents/personal/home,family,finances,stories
$ ls -l Documents/personal
total 16
drwxrwxr-x 2 shs shs 4096 Jul 7 09:52 family
drwxrwxr-x 2 shs shs 4096 Jul 7 09:52 finances
drwxrwxr-x 2 shs shs 4096 Jul 7 09:52 home
drwxrwxr-x 2 shs shs 4096 Jul 7 09:52 stories

In addition, you can specify a series of subdirectories at multiple levels in the directory tree that you’re setting up. Here’s a very simple example:

$ mkdir -p testing/1,2,3/a,b,c

This will set up three subdirectories within a “testing” directory and three subdirectories within each of those subdirectories. If you have the tree command installed, you can view the new structure with a command like this one:

$ tree testing
testing
├── 1
│   ├── a
│   ├── b
│   └── c
├── 2
│   ├── a
│   ├── b
│   └── c
└── 3
    ├── a
    ├── b
    └── c

In addition, you can add additional subdirectory levels if you need to.

Another option is to use syntax like that shown below to create subdirectories in only one of the new directories. You can do that by adding curly brackets around a portion of the command as shown below so that only the articles directory will be set up with subdirectories.

$ mkdir -p tech/articles/new,old,images,notes,comments

Again, the tree command will give you a useful view of the directory structure you have just created.

$ tree tech
tech
├── articles
│   ├── new
│   └── old
├── comments
├── images
└── notes

Wrap-up

The mkdir command can create complex directory structures and the tree command is perfect for confirming the directory structure you’ve just set up. Keep in mind that you can remove a directory structure with a command like “rm -rf this” if your command didn’t do just what you needed it to do and try again.
