Unfortunately, in most cases, Microsoft's documentation for a PowerShell cmdlet is lacking information about the aliases.
For instance, the documentation for Get-Content fails to include information about the aliases cat, dir, and gci.
Resolution
Running cmdlet Get-Alias in a PowerShell session will list all aliases (for that version of PowerShell).
The interesting fields in the output from Get-Alias are:
"Name" The alias. E.g. "cat"
"Definition" The cmdlet. E.g. "Get-Content"
Get-Alias by itself will (roughly) output in alphabetic order of the aliases. Probably more interesting is grouping by cmdlets and then the aliases for that cmdlet in alphabetic order (sort with primary key on "Definition" and secondary key on "Name"):
Get-Alias | select Name, Definition, DisplayName | sort Definition, Name
If the output is needed in some particular format, e.g. rows in an HTML table:
Get-Alias | select Name, Definition, DisplayName | sort Definition, Name | foreach { "<tr> <td>{0,1}</td> <td>{1,1}</td> </tr>" -f $_.Name, $_.Definition }
Interesting aliases
Some short aliases are:- % is an alias for ForEach-Object. ForEach-Object is also commonly known by another alias, foreach.
- ? is an alias for Where-Object. Where-Object is also commonly known by another alias, where
- h is an alias for Get-History. Another alias is ghy.
- ps (like on Unix) is an alias for Get-Process.
