My small bot for my auto retweet on twitter which is based on python and is hosted on my small raspberry PI:-

• • Install PIP
  • pip install twython
  • Create an application on twitter via https://apps.twitter.com/ in order to get the following variables
    • APP_KEY
      APP_SECRET
      OAUTH_TOKEN
      OAUTH_TOKEN_SECRET
  • The small script (my link on GITHUB soon – sorry for indentation) and save as tweet.py

import time
from twython import TwythonStreamer, Twython , TwythonError


#Twitter app auth
APP_KEY = ''
APP_SECRET = ''
OAUTH_TOKEN = ''
OAUTH_TOKEN_SECRET = ''


#Let's gather a list of words we DON'T want to RT
naughty_words = ["CPU", "TEMP", "courses", "hiring", "load average", "Temperature and humidity sensor", "Comunidade"]
#And a list of words we WOULD like to RT

good_words = ["#linux", "twitter" ]

#OR is Twitter's search operator to search for this OR that
#So let's join everything in good_words with an OR!
filter = " OR ".join(good_words)

# The - is Twitter's search operator for negative keywords
# So we want to prefix every negative keyword with a -
blacklist = " -".join(naughty_words)

#And finally our list of keywords that we want to search for
#This will search for any words in good_words minus any naughty_words
keywords = filter #+ blacklist
#Setting Twitter's search results as a variable
while (True):
 try:
 twitter = Twython(APP_KEY, APP_SECRET, OAUTH_TOKEN, OAUTH_TOKEN_SECRET)
 search_results = twitter.search(q=keywords, count=1)
 #time.sleep(600) 
 for tweet in search_results["statuses"]:
 #print tweet
 try:
 twitter.retweet(id = tweet["id_str"])
 except TwythonError as e:
 print e
 time.sleep(1000)
 except TwythonError as e:
 print e

• Run script, python tweet.py & (for linux shell – to run the application in background.
• A small “monitoring” script to check the status of python tweet.py, if the latter is crashed it will start it automatically

check_tweet.sh

#!/bin/bash
#Check tweets
ps ax |grep -v grep |grep tweet.py
result=$?

if [ "${result}" -eq 0 ]
then
 echo $(date) "Tweet Bot is running"
else

 su - root -c "/usr/bin/python <pathTO>tweet.py &"

fi

create a cron job and the script executable:-
chmod +x /<PatchToscripts>/check_tweet.sh

*/10 * * * sudo /<PatchToscripts>/check_tweet.sh
