- 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
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.

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. 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.

Default zsh is just bash, you need to add all the fancy plugins to get it to do cool stuff
fish is for people who don't want to spend the time setting it all up and to just get a shell that has most of the QoL fetaures builtin.
Fish is for people who like it when sometimes scripts don't work
Why would sometimes scripts not work? All scripts are executed with bash by default.
No, they are executed according to the shebang on the first line, which is usually bash. If it is missing, it will default to the current shell.
I like to gamble what can i say
But I'm a compliant little bitch for POSIX daddy
I tried switching to Nushell but certain things just wouldn't work so I switched back to zsh. sha512sum wouldn't work and there's no native replacement.
So write all your scripts in POSIX compliant bash and use the proper shebang?
You don't even need a proper shebang. Scripts without shebang are executed in bash by fish.
