head replacement on Windows (16 Jun 2009)

Fortunately, this is fairly simple using a few lines of VBScript and the Windows Scripting Host. First, here's the VBScript code:

headlines = WScript.Arguments(0)
Do Until WScript.stdin.AtEndOfStream Or headlines=0
  WScript.Echo WScript.stdin.ReadLine
  headlines = headlines-1
Loop

This is an extremely stripped-down version of head's original functionality, of course. For example, the code above can only read from standard input. Oh, and: Command-line argument validation and parsing left as an exercise for the reader

Assuming you'd save the above into a file called head.vbs, this is how you would display the first three lines of a text file called someinputfile.txt:

   type someinputfile.txt | cscript /nologo head.vbs 3

Enjoy!
