I had to move a file from one location to another and run script named "Irel_Wrapper"
in putty I did /home/location mv filename.
So in Java i used channel(Exec) and I was able to execute the above scenario ie moving the file as "mv" command is a putty command.
But I am not able to run the script Irel_Wrapper (my guess is as its not a putty native command i am not able to do that in java with channel(Exec).
I basically need to open a location with cd command and run the irel_wrapper script. I tried a method , but i was not able to achieve it. Error that i got : Ksh Irel not found.
My code:
public ArrayList<String> deployIrelWrapper() throws JSchException, IOException {
ConnectAndCreateSession();
String GrepComandConsole = null;
StringBuilder sb = new StringBuilder();
Channel channel1 = session.openChannel("exec");
String command = "cd /pre/d02/pinDap75a/opt/ifw/vf/cdr/p3/out/irel && irel_wrapper";
BufferedReader br = null;
java.io.InputStream in = channel1.getInputStream();
((ChannelExec) channel1).setCommand(command);
((ChannelExec) channel1).setErrStream(System.err);
System.out.println("Connect to Channel...");
channel1.connect();
System.out.println("****Channel Connected****");
System.out.println();
String line;
try {
br = new BufferedReader(new InputStreamReader(in));
while ((line = br.readLine()) != null) {
sb.append(line + " ");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (br != null) {
try {
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
ArrayList<String> ResultSet = new ArrayList<>();
ArrayList<String> ResultSetOutput = new ArrayList<>();
System.out.println("Expected output");
String words = sb.toString();
String[] result = words.split(" ");
for (String ss : result) {
ResultSet.add(ss);
}
for (int i = 0; i < ResultSet.size(); i++) {
GrepComandConsole = ResultSet.toArray()[i].toString();
ResultSetOutput.add(ResultSet.toArray()[i].toString());
System.out.println(ResultSetOutput);
}
channel1.disconnect();
session.disconnect();
return ResultSetOutput;
}
Kindly do not make this question duplicate. I am able to execute commands like mv command cd.. or SFTP transfer.. but to execute a script after opening a path with CD command I am not able to get it. I am using Jsch lib.
How its done manually:
I login into putty.
Open the path: cd home/apt/cdr/irel/
run irel_wrapper : irel_wrapper
then list of few other details will get populated like, GSM3A , Voic, NET3B etc..
Next final command: irel_wrapper GSM3A
this is how we do it manually via putty, I tried automating it using java and Jsch. SO SFTP and other simple commands like mv and ls I was able to achieve.. except this Irel wrapper.. but when I do it manually its working fine. Thus No spelling mistake I guess..
