This tool is included in the general distribution version (if not, you can download the tool based on the following connection).

Enter the following command: % S/^ m $ // G # Remove ^ m at the end of the line. : % S/^ m // G # Remove all ^ m. : % S/^ m/[Ctrl-v] + [enter]/G # Replace ^ m with the carriage return. : % S/^ m/\ r/G # Replace ^ m with the carriage return. 3. Use the SED command. Similar to VI usage: $ sed-E's/^ m/\ n/G' myfile.txt Note: Here "^ m" is generated using the CTRL-V CTRL-M, instead of directly typing "^ m ".
