Powershell Native crlf and lf Functions

linefeed.ps1

<#
  switch between crlf and lf much like unix2dos and dos2unix but implemented in powershell.
  put two functions into your $PROFILE and call like the following:
  
  default params is your current working dir and ignoring .git and vendor dirs
   
  crlf file.txt
  crlf ./dir @(".git", "vendor")
    
  lf file.txt 
  lf ./dir @(".git", "vendor")
#>

function crlf([string]$path=$pwd, [string[]]$exclude=@(".git", "vendor")) {
    foreach ($item in Get-ChildItem $path) {
        if ($exclude | Where {$item -like $_}) { continue }
        if (Test-Path $item.FullName -PathType Container) {
          $item.FullName
          crlf $item.FullName $exclude
        } else {
          $item.FullName
          (Get-Content -Path $item.FullName) | Set-Content $item.FullName
        }
    }
}

function lf([string]$path=$pwd, [string[]]$exclude=@(".git", "vendor")) {
    foreach ($item in Get-ChildItem $path) {
        if ($exclude | Where {$item -like $_}) { continue }
        if (Test-Path $item.FullName -PathType Container) {
          $item.FullName
          lf $item.FullName $exclude
        } else {
          $item.FullName
          ((Get-Content -Path $item.FullName) -Join "`n") + "`n" | Set-Content $item.FullName -NoNewline
        }
    }
}
