# Helpful Linux Commands

## Commands

To find in which directory you currently are, use:

```
pwd
```

To list all the files and folders in your directory, use:

```
ls
```

To navigate between directories use *cd* followed by the path or name of the directory you want to access. If you start typing a location that is present in your current directory, you can then use the TAB key to autocomplete the name of a directory.

```
cd <directory>
```

To go up one directory, use:

```
cd ..
```

To go back to the root (*/home/\<user>*), use:

```
cd ~
```

To delete a file, use:

```
rm <filename>
```

To delete a directory, use:

```
rm -r <directoryname>
```

Now that you have run multiple commands, and that you will be launching Empirica apps, there are a few useful tricks you should know:

* Use **ctrl+l** to clear your command line.
* Use **ctrl+c** to cancel (whilst writing it) or interrupt (when it is running) a command.

## Tips for Windows WSL users

```
explorer.exe .
```

Nevertheless, you will also need to get accustomed to using the command line to navigate in, and use, the the files and folders in your WSL directory. Here are some useful commands.
