| .SYNOPSIS | |
| Verifies that the file hash of a PowerShell open-source installer matches expected value. | |
| .DESCRIPTION | |
| Compares the file hash of a PowerShell open-source installation file to the expected file hash value. Supports | |
| all installation file types, including msi, zip, rpm, deb, pkg, and tar.gz, beginning with installers for PowerShell | |
| release 6.0.0.9. | |
| To get a list of installer file names, but not test the file hash, use the ListOnly parameter. | |
| To verify the file hash, enter the path and name of the installer file. Test-PSFileHash returns a Boolean value. | |
| .PARAMETER Path | |
| Enter the path and file name of the installer file. If you omit the path, the default is the local directory. | |
| .PARAMETER ListOnly | |
| Returns only the names of installer files for which this script stores file hashes. | |
| .OUTPUTS | |
| string, boolean | |
