Community rules (click to expand)
1. Follow the site-wide rules
- Instance-wide TOS: https://legal.lemmy.world/tos/
- Lemmy code of conduct: https://join-lemmy.org/docs/code_of_conduct.html
2. Be civil
- Understand the difference between a joke and an insult.
- Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
- Don't get baited into back-and-forth insults. We are not animals.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry of any kind will not be tolerated. This is an LGBTQ+-friendly community -- if that is a problem for you, you should leave.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudoin Windows. - No porn, no politics, no trolling or ragebaiting.
- Don't come looking for advice, this is not the right community.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, <loves / tolerates / hates> systemd, and wants to interject for a moment. You can stop now.
5. 🇬🇧 Language/язык/Sprache
- This is primarily an English-speaking community. 🇬🇧🇦🇺🇺🇸
- Comments written in other languages are allowed.
- The substance of a post should be comprehensible for people who only speak English.
- Titles and post bodies written in other languages will be allowed, but only as long as the above rule is observed.
6. (NEW!) Regarding public figures
We all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations. - Keep discussions polite and free of disparagement.
- We are never in possession of all of the facts. Defamatory comments will not be tolerated.
- Discussions that get too heated will be locked and offending comments removed.
Please report posts and comments that break these rules!
Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't remove France.

MODERATORS
The way they do it is fundamentally different. Head just reads until number of newlines is the target number. Tail has to first read the entire file and keep a buffer of the file and/or offsets for each line ending to determine what the last 10 (or so) lines are.
This idiot (Gabriel) probably thinks exclusively in the real world paper line analog.
I also just looked at each program's command line options and they're identical. Less things only Tail can do (because they're fundamentally different operations)
Typical of Internet discourse to just immediately brand someone you disagree with an idiot... That "idiot" is one of the designers of common lisp, among other things. You're allowed to disagree with a smart person too you know
OK. Designers of programming languages can be idiots.
Lisp is a bad language IMO. Way too mathy. Nobody programs like that anymore for a reason.
Programming language is a tool. Do you think there's no more tasks left where "mathy" programming language would be preferable?
