    A close call a long time ago with ubuntu and the terminal

    A long, long time ago, I was on a forum and say someone telling me to sudo rm recursive /.
    I was bored and forgot to type sudo.
    I am thankful that I did. XD
    If only I knew his name, that's quite mean telling someone to wipe there hard disk. Now there is a pleasant warning.

    More than mean. If the intent was malicious, that is one thing that can lead to an instant ban here.

    If you see anything similar, please report it so that the staff can deal with it.

    It was on askubuntu. Unfortunatly, I had to go before I could get there un. I really really hate this guy because he probably caused plenty of curious users dismay. D: You should add a filter for hese commands, if so, they have the words DO NOT RUN imprinted upon them and auto-send to staff.

    The forum staff is quite small.
    We would not be able to do basic moderations if every command instruction had to be reviewed.
    However, if you come across suspicious commands such as the one you pointed out, report it using the report post button and then the staff will take the time to review it and take whatever action is needed.

    Did you read the announcement I linked to?

    We are not going to filter that or any command, because it could interfere with constructive and helpful advice posted here. People need to be educated about potentially destructive commands, whether used maliciously or by accident - hence the announcement. But we also rely on people reporting suspicious stuff so that the staff can take appropriate action. You are relatively new here, so you may not know that experienced members here are good at reporting stuff they are uneasy with. The staff are grateful to such members - without them it would be much more difficult to keep this forum a place the majority can find congenial.

    I second that largely. Without them it would be a dog's breakfast, a free-for-all, and mostly unmanageable.

    The only advice I can give is never run a command someone tells you to without verifying it from another source.

    coffeecat is correct the site would grind to a halt if every post had to be moderated before it was posted and because commands which are harmful in one circumstance may be good in another it would not be possible to set up automatic filtering.

    There are plenty of people here who if they gave me instructions to do something I would follow without double checking. But, certainly not if I didn't recognise the screen name and know they had a reputation for giving good advice.

    That said the majority of people on this site are really good. You get the occasional idiot anywhere.

    If you do spot anything that's malicious however report it with the Report post button at the bottom left of each post or in Forum Feedback & Help. The moderators can remove posts and I'm sure they are happy to ban a user who persists in dangerous posts.

    I agree with the above posts, but I have a couple of comments.

    Certain obscene words are filtered and replaced with asterisks. The very worst commands, like removing all files from root would certainly also be possible to filter in the same way if we really want to.

    But there is no way to filter all potentially dangerous commands. Instead we must encourage each other to backup everything that we don't want to lose because things happen related to software (including malicious commands) as well as hardware (including the power grid and theft).

    Warnings do not always work. Think of those people who install Ubuntu by selecting Use the Entire Disk and are then surprised that Ubuntu is installed and Microsoft Windows is no longer on the hard drive.
    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.

    Re: A close call a long time ago with ubuntu and the terminal

    The problem with Windows and OSX is they like to obscure all the yucky geeky stuff from users so they don't have to deal with it, but people don't learn how operating systems work anymore. Even Linux people have a tendency to copy and past commands from the Internet to fix a problem without really understanding what they are doing. People really need to learn how the command line works or they are susceptible to this sort of thing. So, don't ever use a command unless you know what it does first.
