    Short answer: Nothing

    Long answer: It is part of a command that deletes everything. The only thing missing is the argument specifying what to delete. Examples:

    rm -rf *
rm -rf /some/directory

    It’s somewhat (in)famous because it’ll do so without asking for confirmation. The only exception is rm -rf / on a modern distro which will complain that you’re attempting to delete EVERYTHING on the system. In the olden days it’d just do it, but these days it tells you to add --no-preserve-root as well if you really wish to do so.

    You have it backwards.

    rm -fr /* removes the French language pack that comes preinstalled on your system.

    /j

    It will delete everything in the directory after that, without asking for further confirmation.

      Unless it’s on /, where preserve-root should be kicking in, unless the bypass flag is used (can’t remember this one)

        Not all systems have the preserve-root flag enforced, actually… I accidentally did the rm -rf / in a bash script (the variable for the path returned empty), and it irreversibly deleted a bunch of my system, including sudo and a big part of /etc, before I realized and did Ctrl+C. However the damage was done, rendering the system both unusable and unbootable. Fortunately I managed to recover some data, as the drive was not encrypted.

        Edit: Yes, like a fool I ran the script as sudo… I am now older and wiser.

          What distro was this out of curiosity? As far as I’m aware preserve-root enforcement comes from upstream coreutils

      No, it does nothing.

      $ mkdir test
$ cd test
~/test$ touch 1 2 3 4 5
~/test$ rm -rf
~/test$ ls
1  2  3  4  5

      If you dont specify the -f option, which among other things tells rm to be quiet, it throws an error:

      $ rm -r
rm: missing operand
Try 'rm --help' for more information.

        Because you’re using it on nothing.

        $ mkdir test
$ cd test
~/test$ touch 1 2 3 4 5
~/test$ cd ..
$ rm -rf test
$ ls

        No more test folder.

            What are you talking about? The does exactly what I said it does.

            It only does nothing for you because you used it incorrectly (in the wrong folder without the required argument).
