Write a script that reads a file periodically $($every $10$ seconds$).$

The file represents the $$command$$ or $$commands$$ that your script is to process in the background.

Every $$valid$$ command in the file will begin with $$simon says:$.$

The REMAINING part of the line is some text that needs to be appended to another $$destination$$ file using $$echo$$ external program.

If the line does not start with $$simon says$,$ output $$hackers$$ and a list of current users to a separate file.

Apply the secure coding principles as needed. My answer is below. Let me know if it is correct please. import os

import time

import subprocess

def process$\_$command$($command$)$:

if command.startswith$("$simon says:"$)$:

text$\_$to$\_$append $=$ command$[$len$("$simon says:"$)$:$].$strip$()$

append$\_$to$\_$file$($text$\_$to$\_$append$)$

else:

report$\_$hackers$()$

def append$\_$to$\_$file$($text$)$:

try:

with open$("$destination$\_$file.txt$","$a$")$ as destination$\_$file:

destination$\_$file.write$($text $+"$

$")$

print$("$Command processed successfully."$)$

except Exception as e:

print$($f$"$Error appending to destination file: $\{$e$\}")$

def report$\_$hackers$()$:

try:

users $=$ subprocess.check$\_$output$(["$who$"]).$decode$("$utf$-8").$strip$()$

with open$("$hackers$\_$report.txt$","$w$")$ as report$\_$file:

report$\_$file.write$("$hackers

$")$

report$\_$file.write$($users$)$

print$("$Hacker report generated."$)$

except Exception as e:

print$($f$"$Error generating hacker report: $\{$e$\}")$

def main$()$:

while True:

try:

with open$("$commands$.$txt$","$r$")$ as commands$\_$file:

for line in commands$\_$file:

process$\_$command$($line$.$strip$())$

except Exception as e:

print$($f$"$Error reading commands file: $\{$e$\}")$

time.sleep$(10)$

if $\_\_$name$\_\_=="\_\_$main$\_\_"$:
