- 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 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. π¬π§ Language/ΡΠ·ΡΠΊ/Sprache
- This is primarily an English-speaking community. π¬π§π¦πΊπΊπΈ
- Comments written in other languages are allowed.

- 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.

Why? All the usual shell scripts don't use Fish as interpreter.
No posix compliance is a headache. (Where the hell are my aliases!?) And also most scripts need to be executed in a posix-compliant shell.
Simple. Just add #!/bin/bash to the start of your script and call it a day.
Or use #!/usr/bin/env bash if you're goated with the sauce. This won't work if you're not goated with the sauce.
Those who are goated with the sauce know what's up.
Whatever you do, do not link /bin/sh to /bin/fish.
That's why there is that shebang thingie in first line. Distributions like Debian use an entire different shell from bash for scripts: https://manpages.debian.org/buster/dash/dash.1.en.html
why use aliases (they exist in fish) when you can use abbreviations and your history isnt determined by whatever you set your aliases up as? If you change an alias, your history does not reflect that. If you use abbreviations, your history is perfectly usable
The fuck is an abbreviation? Is it a knock-off alias?
basically a text expansion. I have g=git, so when I type "g push" after I hit space after g, it expands it to git in the terminal as if i just typed out git myself. My history doesnt show "g push" it shows "git push" before I push enter

Been using fish for years and did not know this.
