Thescommand is a shortcut forsearch. Multiple words are matchedindividually:

Use standard shell quoting for more literal matches:

The(command (shortcut)) ************** pcan be used to print specific codepoints or groups of codepoints:

And finally, there is the
emojicommand (shortcut:e), which is the real reason I wrote this:$ uni e cry 😢 crying face Smileys & Emotion face-concerned Oud loudly crying face Smileys & Emotion face-concerned 😿 crying cat Smileys & Emotion cat-face 🔮 crystal ball Activities game
Filter by group:$ uni e-groups hands 🤲 palms up together People & Body hands 🤝 handshake People & Body hands Apping clapping hands People & Body hands 🙏 folded hands People & Body hands 👐 open hands People & Body hands 🙌 raising hands People & Body hands
Group and search can be combined:$ uni e -groups cat-face grin 😺 grinning cat Smileys & Emotion cat-face 😸 grinning cat with smiling eyes Smileys & Emotion cat-face
Apply skin tone modifiers with
- tone$ uni e -tone dark -groups hands 🤲🏿 palms up together People & Body hands 🤝 handshake People & Body hands [doesn't support skin tone; it's displayed correct] Apping clapping hands People & Body hands 🙏🏿 folded hands People & Body hands 👐🏿 open hands People & Body hands 🙌🏿 raising hands People & Body hands
The default is to display all genders ("person", "man", "woman"), but this can be filtered with the
- genderoption:$ uni e -gender man -groups person-gesture 🙍‍♂️ man frowning People & Body person-gesture 🙎‍♂️ man pouting People & Body person-gesture 🙅‍♂️ man gesturing NO People & Body person-gesture 🙆‍♂️ man gesturing OK People & Body person-gesture T man tipping hand People & Body person-gesture 🙋‍♂️ man raising hand People & Body person-gesture 🧏‍♂️ deaf man People & Body person-gesture 🙇‍♂️ man bowing People & Body person-gesture Face man facepalming People & Body person-gesture 🤷‍♂️ man shrugging People & Body person-gesture
Both  - tone
and  - genderaccept multiple values.  - gender women, manwill display both the female and male variants (in that order), and  - tone light, darkwill display both a light and dark skin tone; useallto display all skin tones or genders:$ uni e -tone light, dark -gender f, m shrug 🤷🏻‍♀️ woman shrugging: light skin tone People & Body person-gesture 🤷🏻‍♂️ man shrugging: light skin tone People & Body person-gesture 🤷🏿‍♀️ woman shrugging: dark skin tone People & Body person-gesture 🤷🏿‍♂️ man shrugging: dark skin tone People & Body person-gesture
Alternatives****************************
https://github.com/sindresorhus/emoj
Doesn't support emojis sequences (e.g. MAN SHRUGGING is PERSON SHRUGGING   MAN, FIREFIGHTER is PERSON   FIRE TRUCK, etc); quite slow for a CLI program (emoj smilingtakes 1.8s on my system, sometimes a lot longer) , search results are pretty bad ( shrugreturns unamused face, thinking face, eyes, confused face, neutral face, tears of joy, and expressionless face ... but not the shrugging emoji), not a fan of npm (has  (dependencies).
https://github.com/Fingel/tuimoji
Grouping could be better, does not support emojis sequences, only interactive TUI, feels kinda slow-ish especially when searching.


**************************************************************************** GUI**************************

gnome-characters
Uses Gnome interface / window decorations and won't work well with other WMs, does not deal with emoji sequences, I don't like the grouping / ordering it uses, requires two clicks to copy a character.

	

			
	

			


		
			
			
					
			
		


gucharmap
Doesn't display emojis, just unicode blocks.


KCharSelect
Many KDE-specific dependencies ( (M). Didn't try it.


https://github.com/Mange/rofi-emojiand (https://github.com/fdw/rofimoji) ***********
Both are pretty similar to the dmenu / rofi integration of uni with some minor Differences, and both seem to work well with no major issues.


gtk3 emoji picker (Ctrl ; or Ctrl . in gtk 3. 93 or newer)
Only works in GTK, does work withGTK_IM_MODULE=xim(needed for compose key), for some reasons the emojis look ugly, doesn't display emojis sequences, Doesn't have a tooltip or other text description about what the emoji actually is, the variation selector doesn't seem to work (never displays skin tone?), does work in Firefox.
This is so broken on my system that it seems that I'm missing something for this to work or something?


https://github.com/rugk/awesome-emoji-picker************

Only works in Firefox; takes a tad too long to open; does not support skin tones.


Didn't investigate:
