# 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>
```

```
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>
```
