Parameters, values, and parameter sets
As seen while looking at syntax in Get-Help
, commands accept a mixture of parameters. The following sections show how these parameters are described in help and how to use them.
Parameters
When viewing help for a command, several different conventions are used to describe when a parameter is required and how it should be used. These conventions include:
- Optional parameters, where parameter names and arguments are enclosed in a single pair of square brackets.
- Optional positional parameters, the same as an optional parameter but with the parameter name also enclosed in square brackets.
- Mandatory parameters, where the parameter name and argument are not bracketed.
- Mandatory positional parameters, where the parameter name is in square brackets, but the argument is not.
The following sections show each of these conventions in greater detail.
