= Listing files and directories =

* <code>ls</code> is the most common command of all. It lists files and folders in your current location.
* By default it requires no arguments and will list in alphabetical order
* Although it has options, using it with wild card (especially the asterisk) can help control it

== Some practice ==
* List all the files in the directory hdi2u_files. that start with the letters tes
ls tes*

* List all the files in your directory that start with tes, and end in 1.embl, 2.embl or 3.embl
ls tes*[123].embl

== Questions ==

* Prefix the asterisk wildcard with a dot, what do you get?
* Try the -l option, what type to listing are you getting?
* What does it tell you about the whatsinaname.fasta?
* Specify the directory to ls, did something unexpected happen?
* <code>ls</code> has what should be called a companion command: <code>pwd</code>. Try it.
* If <code>ls</code> is the most commmon command, what might the most common typo be?
