 ## Objectives
 
 1. In this lab students will learn to navigate their file system using only the terminal
-2. Students will practice using the following commands to traverse directories and investigate their contents: `pwd`, `ls`, `cd`, `cat`, `less`, `grep`

 ## Overview
 
 There are many text editors out there. We will be using an editor called VIM (short for VI iMproved -- it is a clone of the editor VI with some improvements). Other options that you can explore on your own include emacs and nano (a clone of a program called pico). Here are the VIM commands we'll use along with a few other useful basics (there are many, many, many many more):
 
-- `:w` - Write; writes the current contents of the buffer (editor) to a file. 
+- `:w` - Write; writes the current contents of the buffer (editor) to a file.
 - `:q` - Quit; Quits VIM. Complains if you have unsaved changes (use `:w` first, or `:q!` to force quit and abandon your changes)
 - `:set number`/`:set nonumber` - Enables/disables line numbers.
 - `a` - Switch to insert mode after the current character. `A` goes to the end of the line instead.
 - Now you're stuck without your prompt; but we can fix that! Press `Ctrl`+`Z` to suspend (not kill) that program.
 - Now you've got your terminal back, but if you type `jobs` you'll see that python is currently stopped. You can bring it back with `fg`, but that will block your prompt again; instead, use `bg` to resume it in the background.
 - Now that you've resumed python in the background, you can see it listed as running in `jobs`. Bring it back to the foreground with `fg` and then kill it with `Ctrl`+`C`
