x2y: convert line ending between DOS, Mac and Unix

Project description

Convert line ending between DOS, Mac (pre OS X) and Unix


  • DOS = ‘\r\n’
  • Mac = ‘\r’ (OS9)
  • Unix = ‘\n’

Note: Mac here is OS9 and earlier. OS X line endings are Unix.


Convert From Unix To DOS Line Endings

$ x2y -f unx -t dos file.txt

The above command will convert Unix line ending to DOS line endings. The result is written back in to the source file.

If you want to write to another file use the -o or -d options (see below).

$ x2y -o output.txt -f unx -t dos file.txt

Will write the converted file to output.txt

$ x2y -d outputs -f unx -t dos file.txt

Will save converted files to the outputs directory.

To back up the source file use the -b option. For example:

$ x2y -b bak -f unx -t dos file.txt

Will rename the source file with a “.bak” extensions before writing the converted file.


pip install x2y
