It provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes. dos2unix 7.5.2 dos2unix is a classic command line tool to convert between the different linebreak types of CRLF on DOS/Windows, plain LF on Unix systems, and CR on Mac systems.
