  • In Uni I ran Gentoo as my daily driver. It was stupid, but I learned a lot.

    Trying and failing to get a working desktop environment, using IRC on the command line to get help from people who knew what they were doing and could advise a dumb kid like me, following their advice and getting a working DE after a reboot was the most hackerman I ever felt. I was convinced I was real hot shit. In actuality, I’d followed the advice to tweak the kernel config to get working drivers :))




  • No, this is a very old joke that uses the fact the command has “fr” in it to trick people about what the command does. Joking aside, here’s what the command actually does:

    rm is the command to delete files and folders

    -f is the force modifier. This means it’ll keep going even if it encounters problems and just delete as much as it can

    -r is the recursive modifier. That means it’ll go down every folder it sees in the target and delete the contents as well, and delete the contents of folders of folders, etc.

    / is the target. This is the root of the filesystem. If you’re used to Windows, that’s like targeting C:.

    Put it all together, and this command basically deletes your whole filesystem. A safeguard was put in place a while back due to people meming about this and causing newbies to delete their whole system. Now it won’t work unless you put in --no-preserve-root, which tells rm that yes, you really mean it, please delete my whole system.

    /* as the target works around that safeguard, because technically deleting everything in root is not the same as deleting root itself.
