Process Runtime pass input

Question

I have rsync command to be run in a java program...the problem i am facing is that rsync requires a password to be entered and i am not understanding how to pass this passwo

Answer 1

I was gonna post this code sample:

Process rsyncProc = Runtime.exec ("rsync");
OutputStreanm rsyncStdIn = rsyncProv.getOutputStream ();
rsyncStdIn.write ("password".getBytes ());

But Vineet Reynolds was ahead of me.

As Vineet Reynolds pointed out using such approach will require an additional piece of code to detect when rsync requires a password. So using an external password file seems to be an easier way.

P.S.: There may be a problem related to the encoding, it can by solved by converting the string to a byte array using appropriate encoding as described here.

P.P.S.: It seems that I can't yet comment an answer, so I had to post a new one.
