Powershell, using contains to check if files contain a certain word

Question

I am trying to create a powershell script which looks through all files and folders under a given directory it then changes all instances of a given word in .properties file

Answer 1

The simplest way to check that file contains the word

If we are looking at Get-Content result we find string System.Array. So, we can do like in System.Linq in .NET:

content.Any(s => s.Contains(wordToFind));

In PowerShell it looks like:

Get-Content $filePath `
            | %{ $res = $false } `
               { $res = $res -or $_.Contains($wordToFind) } `
               { return $res }

As a result, we can aggregate it in cmdlet with params of file path and containing word and use it. And one more: we can use Regex with -match instead of Contains, so it will be more flexible.
