This is a python script to post birthday wishes on the Facebook timelines of the friends who have birthdays.
For Linux
run fb_bdaywish.py on the terminal
The terminal will prompt you to enter the Username and Password of your Facebook account. After you enter the credentials, the script will open "Mozilla Firefox" browser, log in to your account, open the birthdays page and start posting the birthday wish "Happy Birthday!!"
Note: If you want to write your own custom birthday message, replace the string "Happy Birthday!!" on line #40 of the python script with your custom text.
