|I am following the suggestions given in this reply to use
|tar -c -f -z folder to speed up the download transfers.
|I tried it in my program, it is said just send the output to std output
|and later piped and save it in a file.
|Is there any example to show how to do that. I would really appreciate that.
Suppose that if you want to do following ssh command operations in JSch APIs,
$ ssh f...@example.com "(cd /usr; tar czf - src)" > /tmp/foo.tgz
how about following chunk of code?
Channel channel=session.openChannel("exec");
String command="(cd /usr; tar czf - src)";
((ChannelExec)channel).setCommand(command);
java.io.FileOutputStream out = new java.io.FileOutputStream("/tmp/foo.tgz");
channel.setOutputStream(out);
channel.setInputStream(null);
((ChannelExec)channel).setErrStream(System.err);
channel.connect();
while(true){
if(channel.isClosed()){
System.out.println("exit-status: "+channel.getExitStatus());
break;
}
try{Thread.sleep(1000);}catch(Exception ee){}
}
channel.disconnect();
out.close();
Sincerely,
