Counting lines of source code with PowerShell

Published October 31, 2007 PowerShell , software , software development 7 Comments

How do you count the lines of code your application has? As far as I know Visual Studio does not provide this functionality, so needless to say, we are doing that with PowerShell 😉

$num = 0
dir c:\root\ -include *.cs -Recurse | ForEach-Object { 
	$file=[array](Get-Content $_ ) 
	$num += $file.length 
}
$num

You obviously need to change c:\root to your root folder path, and change the *.cs mask to the one applicable to your source code.

Another approach would be:

dir c:\root\ -include *.cs -Recurse | Get-Content | Measure -Line

Make that Measure-Object (measure is an alias I set up).

By the way, “-filter *.cs” is a lot faster than “-include *.cs” … personally I like to not count empty lines, so I filter them out with something like:

ls -recurse -filter *.cs | gc | ? { -not $_.Trim().Length -eq 0)) } | measure-object -line

If you don’t want to count the comment lines, you could also filter those out (note that you have to change your comment string if you’re not working on C#, and that this doesn’t exclude /* comment blocks */)

ls -recurse -filter *.cs | gc | ? { $str = $_.Trim(); -not ($str.StartsWith(“//”) -or ($str.Length -eq 0)) } | measure -line

Joel, measure-object -line will skip empty lines by default. But for other commands you can filter empty lines just this way: |?{$_}

Wow, I didn’t know about Measure-Object – it turns the script into a real one-liner – which is always the goal here, right? 😉

Learning something new every day! Thanks guys!
