Community rules (click to expand)

1. Follow the site-wide rules

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 will not be tolerated.
    • 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 sudo in Windows.
  • No porn, no politics, no trolling or ragebaiting.
    • 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 figuresWe 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.

    Which one of these commands is correct?

    A: sed -E 's/\b(\w+)\b/echo \1 | rev/g' file.txt
    B: sed 's/\b\w+\b/echo & | rev/ge' file.txt
    C: sed -E 's/(\w+)/$(echo \1 | rev)/g' file.txt
    D: sed 's/\([a-zA-Z]\+\)/\n&\n/g; s/\n\(.*\)\n/\3\2\1/g; s/\n//g' file.txt

    Chatty was so kind to transcribe. May contain errors.

    It's interesting that Google doesn't even get all the text. I had to manually extend the selection and that still misses the "t" on the end of answer D, munches C and more alarmingly changes the case for "-E".

    OCR of fonts used to be a solved problem, but now we have AI, which can sort of do it sometimes

    [–] vivendi@programming.dev 4 points 6 days ago

    Any good OCR model also uses "AI"

    And LLMs are usually really good at detecting text
