man, help or a ? are the most common options you may find on Windows, macOS, or Linux environments to find help or a manual about various tools or commands for an application. If you are using PowerShell and wondering what is the equivalent of this command, well its a cmdlet named Get-Help.
As you may have already guessed, every command in PowerShell starts with a verb like GET- or a SET-, so is for the help command.
Let us see a few examples:
PS /Users/c2ctech> GET-Help Get-Date
NAME
Get-Date
SYNTAX
Get-Date [[-Date] <datetime>] [-Year <int>] [-Month <int>] [-Day <int>] [-Hour <int>] [-Minute <int>] [-Second <int>]
[-Millisecond <int>] [-DisplayHint {Date | Time | DateTime}] [-Format <string>] [-AsUTC] [<CommonParameters>]
...
Note: You may see the below remark when you try to get help (especially if using pwsh on Linux or macOS).
