Linux under ^m

Use VI under Linux to see some text files created under Windows, and sometimes find some "^m" at the end of the line. There are several ways to handle this.

Note: Under Linux, the ^m character can be typed through ctrl+v,ctrl+m, but the ^min the regular expression must be typed in this way, otherwise the regular expression does not match ^m Characters, so you cannot copy and paste the following code directly.

1. Use the Dos2unix command. A gadget that comes with the system.
   Dos2unix yourfile.txt #去掉末尾的 ^m
2. Use the Replace function of VI. Start VI, enter command mode, and enter the following command:
   :%s/^m//g # Remove all the ^m
3. Use the SED command.
   $ Sed-e ' s/^m//g ' yourfile.txt
