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 will not be tolerated.

These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.

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. Even if you watch it on a Linux machine.

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.

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.

fuck() {
    sudo $(fc -ln -1)
}

This function takes the last command and puts sudo in front of it. Actually used it in a zoom call at work without thinking and it took a second to realize why everyone was laughing. Not my invention--came across it years ago on stackoverflow or someplace and thought it was funny/useful.

kmirl@tux:~$ ls /root
ls: cannot open directory '/root': Permission denied
kmirl@tux:~$ fuck

Isn't this the same effect as just running 'sudo !!' ?

According to this super user question, someone said that !! won’t work in a function, so you must use the fc -ln -1 command in a subshell instead. Note the response that says eval shouldn’t be used (not sure why)
