This solution was created using a Linux terminal. A terminal on a Mac OS will look similar. If you're on Windows, instead of
[myComputer Desktop]$
You may see something more like:
C:\Users\currentUser\Desktop>
Solution
Make sure the terminal is navigated on the Desktop
[myComputer Desktop]$
If you type ls, you should see the contents of the Desktop.
If you are not on the Desktop or would like to place your pdx_code directory somewhere else, use cd <DIRECTORY_NAME> to change directory.
[myComputer ~]$ ls
Desktop Documents Downloads Music Pictures Public Templates Videos
[myComputer ~]$ cd Desktop
[myComputer Desktop]$
Once you've navigated to the desired directory, use the command mkdir to create a directory named pdx_code.
[myComputer Desktop]$ mkdir pdx_code
[myComputer Desktop]$ ls
pdx_code
Now we can navigate into our pdx_code directory
[myComputer Desktop]$ cd pdx_code
[myComputer pdx_code]$
Inside your directory, create a directory for programming_101 and a directory called extra
[myComputer pdx_code]$ mkdir programming_101 extra
Notice mkdir is only executed once, but multiple directories are created by separating their names with spaces
Now if we type ls we see our new directories
[myComputer pdx_code]$ ls
extra programming_101
Navigate into the programming_101 directory
[myComputer pdx_code]$ cd programming_101
[myComputer programming_101]$
Inside the programming_101 directory, create directories for each of the five units for the course: unit_1, unit_2, unit_3, unit_4 and unit_5. Type ls to see the new directories.
[myComputer programming_101]$ mkdir unit_1 unit_2 unit_3 unit_4 unit_5
[myComputer programming_101]$ ls
unit_1 unit_2 unit_3 unit_4 unit_5
Using cd .. navigate back up to the pdx_code directory. The .. refers to the parent directory of the current directory
[myComputer programming_101]$ cd ..
[myComputer pdx_code]$
Create a programming_102 directory. Create a directory for each unit in Programming 102: unit_1, unit_2, unit_3, unit_4 and unit_5
[myComputer pdx_code]$ mkdir programming_102
[myComputer pdx_code]$ ls
extra programming_101 programming_102
[myComputer pdx_code]$ cd programming_102
[myComputer programming_102]$ mkdir unit_1 unit_2 unit_3 unit_4 unit_5
We actually don't need our extra directory. Navigate to the pdx_code directory using the terminal and delete it using rm -r <DIRECTORY_NAME>.
[myComputer programming_102]$ cd ..
[myComputer pdx_code]$ ls
extra programming_101 programming_102
[myComputer programming_102]$ rm -r extra
[myComputer programming_102]$ ls
programming_101 programming_102
