Execute sh my. Sh par and prompt syntax error: unexpected end of file. Why?

Text editing is a file written in notepad in windows and runs in the cygwin simulated Linux environment.

Solution:

This error is caused by the differences in file formats in DOS and Linux.

The text file in DOS uses \ r \ n as the line break Mark, which indicates that the hexadecimal format is 0d 0a. The UNIX text file uses \ n as the line break sign, which indicates that the hexadecimal format is 0a.

In Windows, two line breaks are used: Carriage Return \ r, line feed \ n,In Linux, you only need one \ n symbol..]

In Linux, when a text file in DOS format is opened with a lower version of VI, ^ m is displayed at the end of the line. Of course, it may not be visible, but in VI, the file format is displayed below. "m.txt" [dos] 8l, 72c indicates a DOS file format.

Solution:

Use the following command to set the file format to Unix to solve the preceding error.

vi M.txt:set fileformat=unix:wq
