Files and directories creation using the command line is the first step on becoming a more efficient developer.

Click on the terminal window and:

Create a directory with the name: test$-$dir$1$ in the ~$/$workspace directory

List the ~$/$workspace directory content

Enter the test$-$dir$1$ directory

Print the path to the working directory

Create a file with the name: test$-$file$1.$txt inside the test$-$dir$1$ directory

List the hidden files

Get back to the ~$/$workspace directory

List files and directories in a vertical column layout.
