    "Since we saw that `rm` is a wrecking ball, we should temper it using the `-i` flag. For safety, we would like `rm` to *always* ask us about deletion. We can instruct `bash` to do this for us by creating an **alias**.\n",

    "    alias rm=\"rm -i\"\n",
    "\n",
    "After executing this, any time we use `rm`, `bash` will instead execute `rm -i`, thereby keeping us out of trouble.\n",

    "One of my favorite aliases is to make `ls` list things more prettily.\n",

    "    alias ls=\"ls -FG\"\n",

    "The `-F` flag makes `ls` put a slash at the end of directories. This helps us tell the difference between files and directories. The `-G` flag enables coloring of the output, also useful for differentiating file types."
