+## Accessing the CMD Process
+If you need PIDs, stdio,stdin, stdout, stderr, etc. access,  for use in your code, or cleaning up, @freemany added in some functionality to get a reference to the child process as the returned value of the ` get ` and ` run ` calls.
+
+
+### Getting Process ID
+
+```javascript
+
+    var cmd=require('../cmd.js');
+
+    var process=cmd.get('node');
+    console.log(process.pid);
+
+```
+
+### Running a python shell from node
+
+```javascript
+const cmd=require('../cmd.js');
+
+const processRef=cmd.get('python -i');
+let data_line = '';
+
+//listen to the python terminal output
+processRef.stdout.on(
+  'data',
+  function(data) {
+    data_line += data;
+    if (data_line[data_line.length-1] == '\n') {
+      console.log(data_line);
+    }
+  }
+);
+
+const pythonTerminalInput=`primes = [2, 3, 5, 7]
+for prime in primes:
+    print(prime)
+
+`;
+
+//show what we are doing
+console.log(`>>>${pythonTerminalInput}`);
+
+//send it to the open python terminal
+processRef.stdin.write(pythonTerminalInput);
+
+```
+
+Output :
+
+```python
+
+>>>primes = [2, 3, 5, 7]
+for prime in primes:
+    print(prime)
+
+
+2
+3
+5
+7
+
+
+```
