Hi there,
My name is Allie Newton and I’m having issues with question 1 in this mkdir exercise. The first question instructs the user to cd 2014/dec then list the files of that directory using ls but how do I execute both commands on the same line? Because if I press Enter after the cd command the console thinks I’m missing the ls command. I’ve tried using spaces and / to separate commands but I still get errors. What am I doing wrong?

The Command Line exercises are a bit different in that the exercises constantly reevaluate your work (e.g. without needing to press a button to save) to determine if you’ve passed each step. In other words, simply using two different lines to first navigate to the correct directory, then listing its contents, will allow you to pass.

On another note, you can execute multiple commands on one line by separating them with a semicolon. By doing this, the next command will be executed regardless if the previous one was successful or failed.

I suggest skipping cd (change directory) and accessing 2014/dec by list.

im putting in 2014/dec and it saying directory but i cant seem to get past that? help

Which step are you stuck on?

am i putting a point somewhere wrong that i cant move on?

Please state which of the instructions you are stuck on and what command you entered when attempting this exercise.

can anyone tell me what i am doing wrong?

Welcome to the forums!

It looks like your current directory is blog/2015/jan. You want to navigate to blog/2014/dec. This means you’ll have to navigate up two directories, then into 2014, then into dec. How can you do this?


You can use .. to navigate up one directory. Refer back to the lessons on the cd command if necessary.

Hello I am stuck on the first question in the mkdir exercise. When I write the exact same line suggested to me by the hint or the warning below, the code still doesn’t seem to work. This is what happens:

Welcome to the forums!

Remember that when specifying a directory you want to navigate to, it must be a child of the current directory/the previous directory in a filepath.

If you’re currently in home/ccuser/workspace/blog/2015/jan, you can’t access 2014/jan. We have to navigate to a directory where we can access 2014, then tack on 2014/jan afterwards. With this in mind, what should you do?
