Command discovery is a systematic way to identify the commands, syntax, data, and modifications required for an automation task. Start with individual PowerShell commands before assembling a script or tool; this exposes incorrect assumptions early and reduces maintenance effort. section 9.1 section 9.7
Use an iterative discovery loop:
- Define the required work: commands to run, data to query, changes to make, and errors to log. section 9.1
- Read help examples, try alternative inputs, and inspect the output at the command line. section 9.1
- Test locally and remotely, then check behavior across supported Windows versions before embedding the command in a tool. section 9.1
- Refine the command as new assumptions, errors, or integration requirements appear. section 9.7
get-command -CommandType Cmdlet -ParameterName ComputerName
Use Get-Command with a parameter name to discover commands that accept a particular kind of input, such as a computer name. section 3.3
Choosing compatible parameter names
When creating a command that accepts a remote computer, inspect core PowerShell conventions before inventing a parameter. ComputerName is the usual exemplar for remoting, FilePath or Path fits file locations, and PSSession represents an existing remoting session. Consistent names help commands connect through the pipeline. section 3.3
