PowerShell commands are usually long. However, PowerShell has aliases. For example, “Get-ChildItem” is the same as “gci” or “dir”.
Working in PowerShell, you'll find yourself needing to know:
# show existing aliases Get-Alias # list all aliases ending in r Get-Alias *r
(“Get-Alias” as alias of “gal”)
# find the cmdlet of alias “dir” Get-Alias dir # or, simply use help help dir
# list aliases of Get-Childitem Get-Alias -definition get-childitem
Note that the above won't return functions. For example, typing “Get-Alias” will list “help” as a alias for “Get-Help”. However,
Get-Alias -definition Get-Help will return a error. This is because, technically, “help” is the name of a function, not alias.

PowerShell has over 200 cmdlets and functions. Often, you need to know if there's a command that does what you want. You can search them by Get-Command.
