What are the Sunnahs reported from the Messenger of Allah, may Allah bless him and grant him peace, concerning the 'Eid prayer, and what should a Muslim do from the moment he enters the mosque before Fajr prayer until the completion of the 'Eid prayer?

Among the recommended Sunnah acts on Eid are: uttering the Takbir from sunset on the last day of Ramadan until the Imam comes out for the prayer, performing ghusl before going to the prayer ground, adorning oneself with clothing, eating before going out for the Eid al-Fitr prayer, going to the prayer from one path and returning from another, walking to the Eid prayer ground, performing two rak'ahs if the prayer is in the mosque, and attending the Eid sermon after the prayer, even if attendance is optional.
