if you're using sh try just putting the who in to be executed. I tried
this on my solaris server and it worked. (but when i tried running it from
a bash shell on solaris it didnt work..only from sh)
import java.lang.*;
import java.io.*;
class ExecuteCmd {
/** execute arbitrary OS command
@param String[] command to be executed by the OS
@return void
@throws N/A
*/
public static void main(String args[]) {
try {
String cmd = "who";
System.out.println("Going to execute : " + cmd);
Process p = Runtime.getRuntime().exec(cmd);
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
// read the output from the command
String s;
System.out.println("Here is the standard output of the
command:\n");
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
}
// read any errors from the attempted command
System.out.println("Here is the standard error of the command (if
any):
\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
}
//wait for end of process and get exit status
int status ;
status = p.waitFor();
if (status != 0) {
System.out.println("The command returned a status of " +
status);
}
} catch (InterruptedException intexc) {
System.out.println("Interrupted Exception on waitFor: " +
intexc.getMes
sage());
} catch (IOException e) {
System.out.println("ExecuteCmd.main() : " + e);
} catch (Exception e) {
System.out.println("ExecuteCmd.main() : " + e);
}
}
}
