dos2unix 7.4.3-1 (s390x binary) in ubuntu kinetic

 This package contains utilities dos2unix, unix2dos, mac2unix,
 unix2mac to convert the line endings of text files between UNIX (LF),
 DOS (CRLF) and Mac (CR) formats.
 .
 Text files under Windows and DOS typically have two ASCII characters
 at the end of each line: CR (carriage return) followed by LF (line
 feed). Older Macs used just CR, while UNIX uses just LF. While most
 modern editors can read all these formats, there may still be a need
 to convert files between them.
 .
 This is the classic utility developed in 1989.
