I am running a script in a java program using:
Runtime.getRuntime().exec()
I am able to open the terminal application using this.
If I give command to run the script. It's happening but I am not able to get the logs in the terminal. I am using MAC. I want to get the logs in the terminal.
You can use a Process variable to get what return from that command, and use method such as: getInputStream(), getOutputStream(), getErrorStream(). Example:
Process p = null;
try {
p = Runtime.getRuntime().exec(....your stuff here)
p.getOutputStream().close(); // close stdin of child
InputStream processStdOutput = p.getInputStream();
Reader r = new InputStreamReader(processStdOutput);
BufferedReader br = new BufferedReader(r);
String line;
while ((line = br.readLine()) != null) {
//System.out.println(line); // the output is here
}
p.waitFor();
}
catch (InterruptedException e) {
...
}
catch (IOException e){
...
}
finally{
if (p != null)
p.destroy();
}
p.getOutputStream, then read processStdInput until EOF and then call p.waitFor();
The Process object returned by the method call above has an getInputStream() method (as well as ones for the error and output streams). You have to read from those if you want to grap the inputs and outputs of your script.
For reference: http://docs.oracle.com/javase/7/docs/api/java/lang/Process.html
in terminal, using > to output the log to file. For example: ls / > rootfolder.txt
Using that way, you can output the log to file and then read the log from the file.
