## Listing options

Obviously we know that in order to list the files and sub-directories in our current directory we use `ls` but here are some of the most useful of the different modifiers:

* `**ls -a**`
  * list and include hidden dot files
* `**ls -l**`
  * list with user permissions, file-size and date-modified (most detailed)
* `**ls ***`
  * list organised by folders one level deep

## Navigation shorthands

* `cd -`
  * Return to the directory you were last in
* `!!`
  * Repeat the last command
