Running command after sudo login

Question

I\'m trying to execute below code to execute sudo commands but I do not know how execute commands after sudo login

String[] command         


        

Answer 1

The sudo su executes a new shell.

To provide a command to the shell you either:

• specify the command on su command-line, like the official JSch Sudo.java example shows:

  ((ChannelExec)channel).setCommand("sudo -S -p '' "+command);
  

• or feed the command to the shell using its standard input, i.e. the same way you provide the password:

  out.write(("command\n").getBytes());
  

  See also Executing multiple bash commands using a Java JSch program after sudo login.

In general, I recommend the first approach as it uses a better defined API (command-line argument).
