In the Unix system, there is only "", or "\ n" at the end of each line.

In the Windows system, each line ends with "", that is, "\ n\ r".

A direct result is that if a file under the Unix system is opened in Windows, all the text will become one line.

If the file in Windows is opened under Unix, there may be an extra ^ M symbol at the end of each line.

Method 1:

In command mode: enter:% s / ^ M / / g and then enter to replace the note, where the input of "^ M" is generated by "Ctrl+v" and "Ctrl+M" keys, respectively.

Method 2:

Use vi to open a text file in vi dos.txt command mode enter: set fileformat=unix:w

Method 3:

Use the sed tool sed's / ^ M / / 'filename > tmp_filename

Method 4:

Since there are more carriage returns under window, of course, by deleting'\ rcarriage', it can also be achieved: tr-d'\ r'.

Method 5: (the most commonly used method)

Press the command under the terminal: $dos2unix filename is directly converted into unix format, and then OK! ~

Sed-I's /\ r Compact 'startup.sh

The default is\ r\ nlinux\ nunix\ r under window.
