If you want to execute shell script or any system command then below code may help you.

Code:
    try {
        Process p = Runtime.getRuntime().exec("uname -a");
        // you can pass the system command or a script to exec command. here i used uname -a system command
        BufferedReader stdInput = new BufferedReader(new 
                InputStreamReader(p.getInputStream()));

        BufferedReader stdError = new BufferedReader(new 
                InputStreamReader(p.getErrorStream()));

        // read the output from the command
        String s="";
        
        while ((s = stdInput.readLine()) != null) {
            System.out.println("Std OUT: "+s);
        }
        
        while ((s = stdError.readLine()) != null) {
            System.out.println("Std ERROR : "+s);
        }
    
        
    } catch (IOException e) {
      
        e.printStackTrace();
    }

Thanks,

uname

UNAME(1)						      General Commands Manual							  UNAME(1)

NAME

       uname - display information about the system

SYNOPSIS

       uname [-amnrsv]

DESCRIPTION

       The  uname  command  writes the name of the operating system implementation to standard output.	When options are specified, strings repre-
       senting one or more system characteristics are written to standard output.

       The options are as follows:

       -a	 Behave as though the options -m, -n, -r , -s, and -v were specified.

       -m	 Write the type of the current hardware platform to standard output.

       -n	 Write the name of the system to standard output.

       -r	 Write the current release level of the operating system to standard output.

       -s	 Write the name of the operating system implementation to standard output.

       -v	 Write the version level of this release of the operating system to standard output.

       If the -a flag is specified, or multiple flags are specified, all output is written on a single line, separated by spaces.

       The uname utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

       sysctl(8), sysctl(3), uname(3)

HISTORY

       The uname command appeared in 4.4BSD.

STANDARDS

       The command is expected to conform to the IEEE Std1003.2 (``POSIX'') specification.
