Tools for batch files (Java+shell for implementation)

Tools for batch files (Java+shell for implementation)

There is a lot of corpus that needs to be handled, and should be able to be directly handled directly with shell scripts.

But the shell script is not familiar, just a few simple commands. Therefore, it is implemented using the Java+shell command.
Perhaps it's best to use shell scripting directly.

Perhaps you have any wonderful method also please tell me Oh! Of course. I have the advantage of this tool, is to assume that through the shell command can not achieve the function, Java implementation, add the corresponding interface can be.
The function inside the tool. Java is responsible for scheduling, and the shell is responsible for detailed functionality. It means that the shell command I wrote was for a single file operation. Java uses loops to invoke those shell commands to implement batching. There are some features that need to be written right now, such as string substitution, Text header or end of content. Text transcoding.

Code design. I left an interface called operation, very easy to join the new text operation function.
