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.
  • 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. πŸ‡¬πŸ‡§ Language/язык/Sprache
  • This is primarily an English-speaking community. πŸ‡¬πŸ‡§πŸ‡¦πŸ‡ΊπŸ‡ΊπŸ‡Έ
  • 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.
  • Β 

    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.

    This could just be one sed command:

    echo $line | sed -E 's/TH|[EL ]|DO//g'
    
    [–] Badabinski@kbin.earth 10 points 2 days ago (8 children)

    no pipe necessary, just

    sed -E 's/TH|[EL ]|DO//g' <<<"$line"

    No sed necessary with extglob enabled:

    echo ${line//@(TH|[EL ]|DO)/}

    I was waiting for someone to come along with this response lmao

    I'm terrible at remembering shell string operation syntax, but this is the ultimate answer.

    [–] sik0fewl@lemmy.ca 1 points 1 day ago (1 children)

    Definitely not the ultimate, since it's not POSIX, but still a nice tidbit.

    [–] Badabinski@kbin.earth 3 points 1 day ago (1 children)

    Idk, writing POSIX-compliant shell is so miserable that I avoid doing it when I can. You can use Bash on BSD and all other unixes, so it's still a relatively portable solution.

    [–] sik0fewl@lemmy.ca 1 points 1 day ago

    True enough, but it's pretty much the same to use sed, unless you need those milliseconds of performance boost.
