There are several ways of creating multiple folders at once in macOS. In this blog post, we will go over two of them:

Using round braces

Suppose we wish to create folders with prefix day_ and the suffix for each folder from 1 to 3:

% mkdir day_{1..3}

The command above will create the folders with the following names: day_1, day_2, day_3.

Using a text file

1. Create a text file where you want to create your folders. For our example, we will call the filename of the text file dirs.txt.

2. In the text file, type the names of the folders you wish to create, each on a separate line. If your folder names have to have a space between them (e.g. day 1) then either type day\ 1 or "day 1".

3. Save the file and exit your text editor if you are using a command line based text editor.

4. Type the following at the command prompt: cat dirs.txt | xargs mkdir.

5. Your directories should be now created.
