In spite of having this blog, sometimes I rewrite a function because I forgot I wrote it already.  Case in point, New-Shortcut.  It was one of my earlier entries in this blog:

http://blogs.msdn.com/b/timid/archive/2009/09/06/powershell-for-non-n00bs-symlinks.aspx

However, the “I should have done this years ago” refers to something else – the fact that I should auto-populate shortcuts for TaskMgr.exe and PowerShell.exe on my Desktop and my StartUp folder on all my machines.

Desktop is $home\Desktop.  The StartUp folder was hidden long ago under $env:AppData, specifically “$env:AppData\Microsoft\Windows\Start Menu\Programs\Startup”.

With this, it becomes as simple as:

@(‘taskmgr’, ‘powershell’) |
% {

    $exe = "$_.exe";
    $lnk = "$_.lnk";

    @("$home\Desktop", "$env:AppData\Microsoft\Windows\Start Menu\Programs\Startup") |
    % {

        if(!(Test-Path -Path "$_\$lnk"))
        {

            New-Shortcut -Target $exe -Path $_;

        }

    }

}

Or, if you don't value readability:

@(‘taskmgr’, ‘powershell’) | % { $exe = "$_.exe"; $lnk = "$_.lnk"; @("$home\Desktop", "$env:AppData\Microsoft\Windows\Start Menu\Programs\Startup") | % { if(!(Test-Path -Path "$_\$lnk")) { New-Shortcut -Target $exe -Path $_; } } }

That's much handier for copy-pasting into a window, though most of this is going into my Grand Unified $PROFILE:
