There are different types of commands that you can run on the PowerShell Command line:
- cmdlet - Name for any powershell builtin command, e.g. get-service, set-location, get-childitem....etc
- aliases - these are nicknames for other commands. You can view a list of aliases using get-alias. It's best to avoid aliases where possible.
- function - Small blocks of powershell codes that are found in powershell scripts. You can also load a function into the current powershell session so that you can call the function in the same was as an ordinary cmdlet. A PowerShell session comes preloaded with a default set of functions, for example the "help" function that we saw earlier.
- workflow - A special kind of function, which we'll cover later on.
- application - an external application. E.g. try running "notepad" or "mspaint" straight from the command line.
The word "command" is a generic term that and this course is used to refer to any of the above.
There are a large number of aliases you can use instead of the typing out the whole cmdlet, here are some commonly used aliases:

If you have experience in using the linux command line, then a lot of these aliases will be familiar to you.
Sometime it can be difficult to write a command even after reading the help pages, that's why powershell comes with a gui wizard in the form of show-command that helps you to write your commands. E.g. if you need help writing a move-item command, then just do:
show-command -Name Move-Item
