Removing ^M from Files in vi                        :g/^M/s///g  how to remove caret M (control char, return char,  new line) in unix, vi editor :g/^M/s///g

Symptom

PART: UNIX, vi
COMPONENT: vi
OS: HP-UX - 10.2
DATABASE: Oracle - 7.3.4
WEB SERVER: <None> - <None>
WEB BROWSER: <None> - <None>

Cause

Resolving The Problem

In transferring a file between OSes, occasionally control or return characters are placed at the end of each line. These are typically only visible in View mode of vi.

To remove these characters from a file:

--Open the file in View mode (command view [filename]).

--Execute the following command
:g/^M/s///g

Note: To enter the ^M into the command, type CTRL+v and CTRL+m consecutively.

Save the file. (It will probably be necessary to force save using :w!)
------------------
in some cases you might need to enter the command as
:%s/^M//g
