invoking linux shell commands via java vs copying sh file

[SaurabhRc Jain]

Hi,

We need to execute 3-4 shell commands from a Java application.
We are able to do it successfully using jcraft jsch library.
Now is invoking each command separately from Java code is better approach than copying a shell file to the target machine & executing as single command from java?
Target machine is over network, so network IO is one aspect.
is there any other difference from design perspective?

Sample code

            java.util.Properties config = new java.util.Properties();
            config.put("StrictHostKeyChecking", "no");
            JSch jsch = new JSch();
            Session session=jsch.getSession(user, host, 22);
            session.setPassword(password);
            session.setConfig(config);
            session.connect();
            System.out.println("Connected");
             
            Channel channel=session.openChannel("exec");
            ((ChannelExec)channel).setCommand(command);
            channel.setInputStream(null);
            ((ChannelExec)channel).setErrStream(System.err);
       
            InputStream in=channel.getInputStream();
            channel.connect();
            System.out.print("Passed..");

Thanks,
Saurabh
