Get a random emoji for your terminal prompt instead of that boring old dollar sign.

Emojify Terminal Prompt Instructions.txt

1. Make sure ruby is installed 

2. Add this to your bash profile:
# emoji prompt
export PS1="\w \$(~/.emoji.rb)  "

2(alt). Or, if you are using zsh, edit your theme and add this to the PROMPT (I put it at the end with a couple spaces after)
$(~/.emoji.rb)  

3. create .emoji.rb and place in same directory as bash profile and with contents: 
#!/usr/bin/ruby
# encoding: UTF-8
emoji = %w{〰 ‼ ⁉ # ⃣ 〽 © ® ↔ ↕ ↖ ↗ ↘ ↙ ↩ ↪ ⌚ ⌛ ⏩ ⏪ ⏫ ⏬ ⏰ ⏳ ▪ ▫ ▶ ◀ ◻ ◼ ◽ ◾ ☀ ☁ ☎ ☑ ☔ ☕ ☝ ☺ ♈ ♉ ♊ ♋ ♌ ♍ ♎ ♏ ♐ ♑ ♒ ♓ ♠ ♣ ♥ ♦ ♨ ♻ ♿ ⚓ ⚠ ⚡ ⚪ ⚫ ⚽ ⚾ ⛄ ⛅ ⛎ ⛔ ⛪ ⛲ ⛳ ⛵ ⛺ ⛽ ✂ ✅ ✈ ✉ ✊ ✋ ✌ ✏ ✒ ✔ ✖ ✨ ✳ ✴ ❄ ❇ ❌ ❎ ❓ ❔ ❕ ❗ ❤ ➕ ➖ ➗ ➡ ➰ ⤴ ⤵ ⬅ ⬆ ⬇ ⬛ ⬜ ⭐ ⭕ 🀄 🃏 🌀 🌁 🌂 🌃 🌄 🌅 🌆 🌇 🌈 🌉 🌊 🌋 🌌 🌍 🌎 🌏 🌐 🌑 🌒 🌓 🌔 🌕 🌖 🌗 🌘 🌙 🌚 🌛 🌜 🌝 🌞 🌟 🌠 🌰 🌱 🌲 🌳 🌴 🌵 🌷 🌸 🌹 🌺 🌻 🌼 🌽 🌾 🌿 🍀 🍁 🍂 🍃 🍄 🍅 🍆 🍇 🍈 🍉 🍊 🍋 🍌 🍍 🍎 🍏 🍐 🍑 🍒 🍓 🍔 🍕 🍖 🍗 🍘 🍙 🍚 🍛 🍜 🍝 🍞 🍟 🍠 🍡 🍢 🍣 🍤 🍥 🍦 🍧 🍨 🍩 🍪 🍫 🍬 🍭 🍮 🍯 🍰 🍱 🍲 🍳 🍴 🍵 🍶 🍷 🍸 🍹 🍺 🍻 🍼 🎀 🎁 🎂 🎃 🎄 🎅 🎆 🎇 🎈 🎉 🎊 🎋 🎌 🎍 🎎 🎏 🎐 🎑 🎒 🎓 🎠 🎡 🎢 🎣 🎤 🎥 🎦 🎧 🎨 🎩 🎪 🎫 🎬 🎭 🎮 🎯 🎰 🎱 🎲 🎳 🎴 🎵 🎶 🎷 🎸 🎹 🎺 🎻 🎼 🎽 🎾 🎿 🏀 🏁 🏂 🏃 🏄 🏆 🏇 🏈 🏉 🏊 🏠 🏡 🏢 🏣 🏤 🏥 🏦 🏧 🏨 🏩 🏪 🏫 🏬 🏭 🏮 🏯 🏰 🐀 🐁 🐂 🐃 🐄 🐅 🐆 🐇 🐈 🐉 🐊 🐋 🐌 🐍 🐎 🐏 🐐 🐑 🐒 🐓 🐔 🐕 🐖 🐗 🐘 🐙 🐚 🐛 🐜 🐝 🐞 🐟 🐠 🐡 🐢 🐣 🐤 🐥 🐦 🐧 🐨 🐩 🐪 🐫 🐬 🐭 🐮 🐯 🐰 🐱 🐲 🐳 🐴 🐵 🐶 🐷 🐸 🐹 🐺 🐻 🐼 🐽 🐾 👀 👂 👃 👄 👅 👆 👇 👈 👉 👊 👋 👌 👍 👎 👏 👐 👑 👒 👓 👔 👕 👖 👗 👘 👙 👚 👛 👜 👝 👞 👟 👠 👡 👢 👣 👤 👥 👦 👧 👨 👩 👪 👫 👬 👭 👮 👯 👰 👱 👲 👳 👴 👵 👶 👷 👸 👹 👺 👻 👼 👽 👾 👿 💀 💁 💂 💃 💄 💅 💆 💇 💈 💉 💊 💋 💌 💍 💎 💏 💐 💑 💒 💓 💔 💕 💖 💗 💘 💙 💚 💛 💜 💝 💞 💟 💠 💡 💢 💣 💤 💥 💦 💧 💨 💩 💪 💫 💬 💭 💮 💯 💰 💱 💲 💳 💴 💵 💶 💷 💸 💹 💺 💻 💼 💽 💾 💿 📀 📁 📂 📃 📄 📅 📆 📇 📈 📉 📊 📋 📌 📍 📎 📏 📐 📑 📒 📓 📔 📕 📖 📗 📘 📙 📚 📛 📜 📝 📞 📟 📠 📡 📢 📣 📤 📥 📦 📧 📨 📩 📪 📫 📬 📭 📮 📯 📰 📱 📲 📳 📴 📵 📶 📷 📹 📺 📻 📼 🔀 🔁 🔂 🔃 🔄 🔅 🔆 🔇 🔉 🔊 🔋 🔌 🔍 🔎 🔏 🔐 🔑 🔒 🔓 🔔 🔕 🔖 🔗 🔘 🔙 🔚 🔛 🔜 🔝 🔞 🔟 🔠 🔡 🔢 🔣 🔤 🔥 🔦 🔧 🔨 🔩 🔪 🔫 🔬 🔭 🔮 🔯 🔰 🔱 🔲 🔳 🔴 🔵 🔶 🔷 🔸 🔹 🔺 🔻 🔼 🔽 🕐 🕑 🕒 🕓 🕔 🕕 🕖 🕗 🕘 🕙 🕚 🕛 🕜 🕝 🕞 🕟 🕠 🕡 🕢 🕣 🕤 🕥 🕦 🕧 🗻 🗼 🗽 🗾 🗿 😀 😁 😂 😃 😄 😅 😆 😇 😈 😉 😊 😋 😌 😍 😎 😏 😐 😑 😒 😓 😔 😕 😖 😗 😘 😙 😚 😛 😜 😝 😞 😟 😠 😡 😢 😣 😤 😥 😦 😧 😨 😩 😪 😫 😬 😭 😮 😯 😰 😱 😲 😳 😴 😵 😶 😷 😸 😹 😺 😻 😼 😽 😾 😿 🙀 🙅 🙆 🙇 🙈 🙉 🙊 🙋 🙌 🙍 🙎 🙏 🚀 🚁 🚂 🚃 🚄 🚅 🚆 🚇 🚈 🚉 🚊 🚌 🚍 🚎 🚏 🚐 🚑 🚒 🚓 🚔 🚕 🚖 🚗 🚘 🚙 🚚 🚛 🚜 🚝 🚞 🚟 🚠 🚡 🚢 🚣 🚤 🚥 🚦 🚧 🚨 🚩 🚪 🚫 🚬 🚭 🚮 🚯 🚰 🚱 🚲 🚳 🚴 🚵 🚶 🚷 🚸 🚹 🚺 🚻 🚼 🚽 🚾 🚿 🛀 🛁 🛂 🛃 🛄 🛅 🅰 🆎 🅱 🆑 🆒 🆓 ℹ 🆔 Ⓜ 🆕 🆖 🅾 🆗 🅿 🆘 ™ 🆙 🆚 🈁 🈂 🈹 🉑 🈴 🈺 🉐 🈯 🈷 🈶 🈵 🈚 🈸 ㊗ 🈲 ㊙ 🈳}
