Delete the ^ M symbol at the end of a file row in Linux

Article Title: Delete the ^ M symbol at the end of a file row in Linux. Linux is a technology channel of the IT lab in China. Some basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems are included. Because the drivers in the DOS and Linux editors are inconsistent with the carriage returns at the end of the file line, in Linux, we often see a ^ M symbol at the end of each line in the C or TXT files, which leads to shell script running errors.

We can use the VI editor command to delete the file.

The following is a method I have invented, similar to that provided by Stone. I used the VI search and replacement command to replace ^ M with a space character.

(1): In VI editing mode, ESC shilt +: Input g/\ ^ M/s/\ ^ M //

Press enter to delete it.

(2): In VI editing mode, ESC shift +: Enter % s/^ M/g

Press enter to delete the file.
