Navigating the Shell

In order to see what our working directory is inside the shell, we are going to use pwd which stands for "print the working directory". You can use the command by typing it in and hitting <RETURN>.

first-last@codermerlin:~$  pwd

After using the command you should see something like the below console line. As long as you haven't moved in the directory you should start off in the home directory.

/home/first-last 

Next, let's try the "ls" command which will list the directories and files in the working directory.

first-last@codermerlin:~$  ls

However no files or directories have been created yet, so there won't be anything to display.

 

We can make a directory by using the command mkdir

first-last@codermerlin:~$  mkdir firstDirectory

first-last@codermerlin:~$  cd firstDirectory

first-last@codermerlin:~$  pwd

/home/first-last/firstDirectory 

first-last@codermerlin:~$  cd ../

first-last@codermerlin:~$  ls

firstDirectory
