Note that line breaks are different for script files in linux from those in Windows.

Note that line breaks in script files in linux are different from those in Windows-Linux general technology-Linux programming and kernel information. For more information, see the following. When compiling the sh script file in linux, note that the file written in notepad in Windows cannot be directly executed in linuxshell, and the following error is prompted:

1: bad interpreter: No file or directory

The reason is: in Windows, the line feed is "\ r \ n", while in linux, "\ n" is not "\ r". When the shell file is written in Windows, all linefeeds are "\ r \ n". The file cannot be executed in shell, and the above error is prompted. Run "File-> conversions-> Dos to Unix" in ultraedit. The converted sh File can be directly executed in linux. In this step, the "\ r" symbol can be canceled.
