I. Description of the problem
1) on windows compiled project, copied to linux and start command, reported the following error:
Second, the cause
1) .sh scripts written in the windows system, so there may be invisible characters, from the figure error term, most likely script file is a DOS format, ie each line end of the line to \ r \ n to identify which are the ASCII code 0x0D, 0x0A.
Third, the solution
1) entering or editing by vim filename vi filename, that is, this is my vim startup_heartbeat.sh
2) then shift +: command mode. By then set fileformat command set ff or view the file format that my following chart: I can see from this file format is dos.
3) modify the file format dos to unix. Command set ff = unix or set fileformat = unix modify, and then perform the set ff or set fileformat, to see if the amendment is successful. That is shown below:
4) Start command, found normal start, so far completed.
