NEVER run a command you don't know the purpose of. That being said, "sfc" stands for "System File Checker." It is a utility that can help restore corrupted windows files. sfc /scannow checks your protected files and restores corrupted files from a local cache. The process can take some time and you MUST let it finish it's entirely.

In conclusion, this command is generally safe to run.

Well, I try to understand why something is included. I've run arch for years (BTW), though my current computers are running Fedora and Debian. I won't say I know everything about Linux or even installing it or booting it, but I do know more than I would if I just followed step by step.

It's the same for me but I didn't always know that much about linux.

Rm stands for remove

-fr stands for the French language

/ stands for your entire system

Don’t trust random internet strangers either

So it's removing French from your system. Sounds like a useful tool on Linux if you don't speak French! Be sure to run as sudo though

Don't forget the --no-preserve-root either. If you leave the roots intact, the French will just grow right back

I prefer the 'ole $sudo dd -i /dev/random -o /dev/sda

[–] Ephera@lemmy.ml 26 points 3 months ago (1 children)

Does it also remove the French language pack?

[–] unmagical@lemmy.ml 2 points 3 months ago

No idea.
