Unix newlines to Windows newlines (on Windows)

Question

Is there a way (say PowerShell, or a tool) in Windows that can recurse over a directory and convert any Unix files to Windows files.

I\'d be perfectly happy with a wa

Answer 1

Converting to windows text could be as simple as:

(get-content file) | set-content file

How about this (with negative lookbehind). Without -nonewline, set-content puts an extra `r`n at the bottom. With the parentheses, you can modify the same file. This should be safe on doing to the same file twice accidentally.

function unix2dos ($infile, $outfile) {
    (Get-Content -raw $infile) -replace "(?

The reverse would be this, windows to unix text.

function dos2unix ($infile, $outfile) {
    (Get-Content -raw $infile) -replace "`r`n","`n" | 
    set-content -nonewline $outfile
}

Here's another version for use with huge files that can't fit in memory. But the output file has to be different.

Function Dos2Unix ($infile, $outfile) {
  Get-Content $infile -ReadCount 1000 | % { $_ -replace '$',"`n" } | 
  Set-Content -NoNewline $outfile
}

Examples (input and output file can be the same):

dos2unix dos.txt unix.txt
unix2dos unix.txt dos.txt
unix2dos file.txt file.txt

If you have emacs, you can check it with esc-x hexl-mode. Notepad won't display unix text correctly; it will all be on the same line. I have to specify the path for set-content, because -replace erases the pspath property.
