Anything like dos2unix for Windows?

Question

I have some shell scripts created on windows I want to run dos2unix on them.

But as I have read that dos2unix works in Linux environment so, is there a way that I can convert my files to UNIX format while working in Windows?

I have already installed CYGWIN but I am facing some issues as

$ dos2Unix BLPDB000

Answer 1

I used grepWin:

• Open the folder containing your files in grepWin
• In the "Search for" section
  • select "Regex search"
  • Search for -> \r\n
  • Replace with -> \n
• Hit "Search" to confirm which files will be touched, then "Replace".

Answer 2

In PowerShell there are so many solutions, given a lot of tools in the .NET platform

With a path to file in $file = 'path\to\file' we can use

[IO.File]::WriteAllText($file, $([IO.File]::ReadAllText($file) -replace "`r`n", "`n"))

or

(Get-Content $file -Raw).Replace("`r`n","`n") | Set-Content $file -Force

To do that for all files just pipe the file list to the above commands:

Get-ChildItem -File -Recurse | % { (Get-Content -Raw -Path $_.Fullname).Replace ("`r`n", "`n") | Set-Content -Path $_.Fullname }
