Welcome to Nushell.

Here are some tips to help you get started.
  * help commands - list all available commands
  * help <command name> - display help about a particular command

Nushell works on the idea of a "pipeline". Pipelines are commands connected with the '|' character.
Each stage in the pipeline works together to load, parse, and display information to you.

[Examples]

List the files in the current directory, sorted by size:
    ls | sort-by size

Get information about the current system:
    sys | get host

Get the processes on your system actively using CPU:
    ps | where cpu > 0
