Line break characters for DOS and Linux

One, vim open window under the file appears ^m

First of all understand that DOS (Windows) created under the file line is ^m\$ (CRLF), and under Linux, only the \$ (LF) to do the break symbol;

(^m\$ actually has no \, except that the editor will make it a special symbol by default, so add a backslash)

This causes the ^m symbol to appear at the end of each line when Vim opens a DOS file

This symbol has a large effect, and if it is a shell script, it can cause the "program cannot execute" state

So how to solve it?

Ii. avoid ^m and solutions on each line

1. Can set the use of the editor to break the

As in sublime text, the option: "Default_line_ending": "System",

That changes with the system, under Windows is Crlf,unix is LF

2. Replacing symbols with commands

Vim command line status input:

:%s/[ctrl-v][enter]//g

The function of the ctrl-v is that the ENTER key is considered a special character, not the end of the vim command.

3. Using the Dos2unix command

such as: Dos2unix-k-n test.txt test.new.txt

-K, which preserves the original mtime time format of the file (does not update the last modified time of the file)

-N, which means preserving the original file and outputting the converted content to a new file

Note:-k-n cannot be written-kn, otherwise the execution is unsuccessful;

And, of course, the corresponding Unix2dos commands, which are used to convert each other.

Specific settings can be viewed through Dos2unix--help
