Get your most common PowerShell commands by inspecting your PSReadLine history

PSParser is ancient and doesn't handle things well; use System.Management.Automation.Parser.ParseInput() instead:

$Errors = $null
$Tokens = $null
$Ast = [System.Management.Automation.Language.Parser]::ParseInput(
    ( Get-Content (Get-PSReadLineOption).HistorySavePath ),
    [ref]$Tokens,
    [ref]$Errors
)
$Tokens | 
    Where-Object { $_.TokenFlags.HasFlag([System.Management.Automation.Language.TokenFlags]::CommandName) } |
    Select-Object Text | Group-Object Text |
    Sort-Object Count, Name -Descending | Select-Object Count, Name -First 20
