Creating Directories and Files

To create a directory structure and files, you can use the following commands:

$ mkdir magic
$ mkdir magic/dir{1..100}
$ touch magic/dir{1..100}/file{1..100}.txt

Alternatively, you can combine the commands into one:

$ mkdir magic; mkdir magic/dir{1..100}; touch magic/dir{1..100}/file{1..100}.txt

Creating a Specific File

To create a file named test.txt in a randomly chosen directory:

$ touch magic/dir$(shuf -i 1-100 -n 1)/test.txt

Finding and Moving Files

  1. To find the test.txt file:

    $ find magic -type f -name 'test.txt'

  2. To move test.txt to the Desktop:

    $ find magic -type f -name 'test.txt' -exec mv {} ~/Desktop \;

  3. To remove all .txt files in the magic directory:

    $ find magic -type f -name '*.txt' -exec rm {} \;
