locate array index with a -match or regex.

[Justin Rich]

basically im trying to find out what line a -match is on.

i know i could do it with a for loop and check each line, but with
everything that PS can do i was wondering if there was some little trick for
it.

Thanks
Justin

Select-String returns <MatchInfo> objects, these have a LineNumber property that is 1-based. PowerShell arrays, like .Net's arrays, are 0-based. All you'd have to do is subtract 1 from MatchInfo.LineNumer to have the index for a 0-based array:

$array = 1, 2, 3, 4, 3, 4, 2, 1, 2, 3, 4
$index = $array | Select-String 3 | % {$_.LineNumber
