Hello

you can find solution in this article:

Running system commands in Java applications | java exec example | devdaily.com

For execution on remote machines check the comments at the bottom
of that article and links there.

So first thing is to get to know how to run external command on local machine:

 Process p = Runtime.getRuntime().exec("my command");

And second - remote machine execution - can be some Socket client/server solution

cheers!

A rest call would certainly be one way. But if you are going to be doing simple command line operations there really isn't a good reason to set up a server. I personally use

JSch - Java Secure Channel

when I want to simply run command line operations on a remote server. Its very useful for running a shell script like you mentioned. It does take some tweaking of the examples to get correct, but I didn't have much of a problem programming it to my needs.
