It means No! Preserve Root.

the / means 'working directory only', a security feature to prevent accidently using absolute paths.

Use sudo before rm to improve efficiency.

I’m very new to Linux; could you explain what this does for me?

OML, this is excellent.
Please, is there a !shitty_linux_advice community?

That's amazing that they would consider auto-generated responses to be appropriate in something which is supposed to be reference documentation. We are a good way from that type of querying and explanation being reliable.

I think AI will cause a massive wave of employment changes. I think people and companies are currently overreacting as to where/how it can and should be used to be effective, but capitalism will make sure in a few more years it is placed where it makes corporations the most money, regardless (and maybe in spite?) of the cost of jobs.

Search engines like Google have cost many people there job; the list of now-rare positions and/or duties associated with a position (thereby thinning the need for such employment) that search engines have replaced is long.

Use --no-preserve-root if you want to keep a backup of the file offsite in Norway.

I refuse to read manpages because I hate mansplaining and I wont have The Man tell me what to do.

Personally I find the built in --help option to be much more useful than manpages. Manpages are excessively wordy and almost never have info I'm looking for without having to search.

Built in help options usually concisely list all the options with a brief explanation of what they do. That's perfect.

My brain once swapped the letters F and L in my head and I typed

iptables -F

Instead of -L.

The standard input policy was drop. It was a VPS and I didn't have access to the management panel. Fun times.

First thing I do is make a recycle bin alias. Everytime.

It's wild it doesn't come like that out of the box.

I'm assuming they've blocked out chemistry from the training data. It's crazy how easy it is to make many things from common chemicals, the liability would be insane.

Is this answer correct? I can't judge, as I have no idea how aspirin active compound is synthetized.

Answer from gtp-4:

Aspirin, also known as acetylsalicylic acid (ASA), can be synthesized through a chemical reaction involving salicylic acid and acetic anhydride. Here's the general process:

1. Salicylic Acid Preparation (if needed): If starting from other compounds like phenol, salicylic acid may need to be synthesized first.
2. Acetylation of Salicylic Acid: Salicylic acid is reacted with acetic anhydride. [ \text{{salicylic acid}} + \text{{acetic anhydride}} \rightarrow \text{{acetylsalicylic acid}} + \text{{acetic acid}} ]
3. Purification: The crude product is often purified by recrystallization, typically using a solvent like ethanol or water.
4. Drying: The purified aspirin is dried to remove any remaining solvent.
5. Characterization: The synthesized aspirin may be characterized using methods like melting point determination, infrared spectroscopy, or other analytical techniques to ensure purity and identity.

In a laboratory setting, the reaction is often catalyzed by an acid such as sulfuric acid, which speeds up the process. The reaction is typically carried out at a moderate temperature, such as around 80°C.

Safety precautions must be taken as the chemicals involved can be corrosive, and proper waste disposal is necessary.
