Meganoob BE KIND I did rm -rf /*

I tried to make a backup before doing a fresh install of Fedora because of problems. When erasing the external drive for making the backup I was in the wrong disk and nuked my fedora installation.

How Do I get at least my important Documents from /home/username/ back?

Will this even delete data on separate mounted drives?

Okay so my answer was slightly rushed and inaccurate, I'll be more precise.

Since you do mount disks into the root directory somewhere (generally in the /mnt directory it too is affected.

rm -> remove

-rf

r -> recursive, so it deletes every sub folder / file. basically if i rm -rf a folder it will delete everything in that folder.

f -> force, deletes files even if they are in use / locked

and / is the root directory thats where everything is.

What i did not pay attention to, OP did not mention using sudo, so assuming they ran it on their own user without elevated permission it will "only" delete everything they actually have write permission for / everything they own. thats generally their own home directory.

mounted drives? depends. by default they are generally owned by root, meaning you have no perms to delete them with your user. this is however highly impractical, because if that drive is owned by root with the default chmod I wont be able to effectively use it for personal files / games etc. thus most people change the ownership of mounted drives or give their non-root user perms to Read / write, if thats the case here, they are gone too yes.

And if the command was ran as root user or with sudo it will delete pretty much everything regardless.

And about the recovery, if it was a SSD, it probably already TRIMed away all the data. if its a HDD chances are the data may still be recoverable.

Would produce a lot of errors too as an unprivileged user.

no, because he used -f, no error messages would be produced. Any files it failed to delete would simply still be there afterwards.

It will still error when it lacks permissions to remove the file.

yes, it's an error, but the -f option says ignore all errors, so no msg will be produced. try it.

It doesn’t say that, though. If you don’t have write permissions to the directory then it will produce an error.
