Convert Text Files from Windows Format to Linux Format and Vice-Versa $ dos2unix $ unix2dos Sooner or later you're going to be sent a file or download one that uses a pair of CR (carriage return) and LF (line feed) characters to terminate lines in the file. Those type of files are Windows/DOS formatted. Unix-like operating systems simply use the LF character to terminate a line. Sometimes this can cause issues. To convert the file to a unix-like format, use dos2unix. To examine the line termination characters use "cat -A" or the "file" command. $
