try {
// Execute a command without arguments
String command = "ls";
Process child = Runtime.getRuntime().exec(command);
// Execute a command with an argument
command = "ls /tmp";
child = Runtime.getRuntime().exec(command);
} catch (IOException e) {
}
If an argument contain spaces, it is necessary to use the overload that requires the command and its arguments to be supplied in an array:
try {
// Execute a command with an argument that contains a space
String[] commands = new String[]{"grep", "hello world", "/tmp/f.txt"};
commands = new String[]{"grep", "hello world", "c:\\Documents and Settings\\f.txt"};
Process child = Runtime.getRuntime().exec(commands);
} catch (IOException e) {
}
