Error while trying to execute a unix shell script from java program
807591Jan 4 2008 — edited Apr 7 2008Hi
I have written a program to execute a unix shell script in a remote machine. I am using J2ssh libraries to estabilish the session connection with the remote box.The program is successfully able to connect and authenticate with the box.
The runtime .exec() is been implemented to execute the shell script.I have given below the code snippet.
..............
try {
File file_location = new File("/usr/bin/");
String file_location1 = "/opt/app/Hyperion/scripts/daily";
String a_mib_name = "test.sh";
String cmd[] = new String[] {"/usr/bin/bash", file_location1, a_mib_name};
Runtime rtime = Runtime.getRuntime();
Process p = rtime.exec(cmd, null, file_location);
System.out.println( "Connected to the server1" );
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = br.readLine();
while(line !=null)
{
System.out.println(line);
line = br.readLine();
}
br.close();
p.getErrorStream ().close ();
p.getOutputStream().close();
int retVal = p.waitFor();
System.out.println("wait " + retVal);
//session.executeCommand("ls");
}
catch (IOException ex) {
}
......
I get an error message
Connected to the server
java.io.IOException: Cannot run program "/usr/bin/bash" (in directory "\usr\bin"
): CreateProcess error=3, The system cannot find the path specified
at java.lang.ProcessBuilder.start(Unknown Source)

I am sure of the file path where the bash.sh and test.sh are located.
Am i missing something? Any help would be greatly appreciated.
Thanks
