# Command-line cheatsheet ## Which folder am I in? You can use the command line to move through folders on your computer, just like with Finder on a Mac or File Explorer on Windows. To see your location in your computer's file system, use the **pwd** (Print Working Directory) command: ```bash $ pwd ``` ## See what's in a folder You can get a list of all the files in your current location, using the **ls** (list) command. ```bash $ ls ``` {% hint style="info" %} Pro tip: anything in the list that is followed by a forward slash is a folder, e.g. `Desktop/` {% endhint %} You can even look at what's inside other folders. Let's say you're currently inside `Desktop/` and you want to see what's inside `Desktop/pics/`, you can do this: ```bash $ ls pics/ ``` ## Go inside a different folder If you want to go from `Desktop/` to `Desktop/pics/`, use the **cd** (Change Directory) command. ```bash cd pics/ ``` #### Go back up to the parent folder If you decide you've had enough of `pics/` and want to go back up the chain to `Desktop/` you need to do something slightly different. `Desktop/` is one folder up, so you need to do this: ```bash cd .. ``` The `..` means the parent folder, i.e. the folder that the current folder lives inside. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
