Shell script to start the program

We all know that the JVM itself provides a lot of commands for users to call. Sometimes we need to use these commands to write some scripts to execute our program. First, let's talk about the directory structure of the following script:

• Bin script Storage

• Lib dependent jar package Storage

• Configuration file storage on which conf depends

• Run the prepared JAR file in the current directory.
