Which PowerShell command helps you search for cmdlets currently available to you?

Which PowerShell command helps you search for cmdlets currently available to you?

• All-Commands
• Get-Command
• Search-Command
• Find-Command

PowerShell Get-Command lists all available PowerShell Cmdlets, Functions and Modules in your computer. I guess you are already beginning to see how helpful PowerShell Get-Command can be.
This is why I said that the Get-Command is a Cmdlet you need to know. The reason is simple. If you need a Cmdlet but you don’t know the Cmdlet or you cannot remember it, PowerShell Get-Command will help you find it.
