Execute another shell script in the shell script

Category:

 

You can execute another shell script (or non-executable file, mainly used to obtain the value of some variables) in one shell script :. file name (including path) or variable = file name (including path ). $ variable Note: there is a space behind the dot. In this way, some variables declared in other files can be referenced in the later part of this shell script. When I use these variables to execute 3rd scripts, I don't know what is going on, and there are always some inexplicable errors. I found that only this file does not contain blank lines, even if there is only one annotator, there will be no error, that is, the rows cannot be empty. In fact, I think this is not the problem, but the difference between processing characters in Windows and Linux. When I write some shell scripts in windows and run them on Linux, errors will often occur, and the display will not be different, that is, running errors, it is often said that the interpreter is wrong and so on, it is puzzling. Therefore, it is best to directly edit it in Linux, as the problem of having to be empty just now suddenly does not exist.
