One Day One Command (By Vishravars Ramasubramanian)
========================================
dos2unix — DOS/MAC to UNIX text file format converter.
Summary:
Each OS will indicate the line end using Line Feed (LF,10) or Carriage
Return (CR,13). So when transferring a file from DOS to Linux, you have
to convert the Line end from DOS format to Linux format.
dos2unix will convert the DOS/MAC Text file to Unix format.
Unix uses LF as line end, Windows/DOS uses CR/LF and MacOS uses CR.
Examples:
$ dos2unix dos.txt — Convert and replace dos.txt.
$ dos2unix -n dos.txt gnu.txt — Convert dos.txt and write into
gnu.txt
$ dos2unix -k dos.txt — Convert and replace a.txt while keeping
original date stamp.
