## Workspace

You can use this workspace to test your commands

Workspace

This section contains either a workspace (it can be a Jupyter Notebook workspace or an online code editor work space, etc.) and it cannot be automatically downloaded to be generated here. Please access the classroom with your account and manually download the workspace to your local machine. Note that for some courses, Udacity upload the workspace files onto https://github.com/udacity, so you may be able to download them there.

Workspace Information:

  • Default file path:
  • Workspace type: repl
  • Opened files (when workspace is loaded): n/a

Research ls -l

Which pieces of information can you find out from ls -l? You may want to do some research to answer this question; use your favorite search engine.
SOLUTION:
  • The name of each listed file or directory.
  • The date and time that a file was last modified.
  • The size of a file, in bytes.

Looking for bear

If you wanted to list all the files whose names start with the word bear, how would you do it?
SOLUTION: `ls bear*`

Recomendation

The Shell commands can be installed or not on your computer if you are using Linux or Mac and you have issues running the commands check the documentation specifically for the Operating System.
