This is a sample code on how to receive data from a form (HTML). The `name` has the command and that is run and output is printed along with status.

cgicode.py

#!/usr/bin/python3

import cgi
import subprocess

print('content-type:text/html')
print()

form_values = cgi.FieldStorage()

data = form_values.getvalue("name")

output = subprocess.getstatusoutput(data)
print(output[0], output[1])
