root shell? Already playing it fast and loose, I see.
The only legitimate commands for a non-root shell are
sudo -i,exit, andecho "yee haw"yee haw
Fun fact there was a guy a little over a decade ago who got drunk and traded 7m barrels of oil futures. Not dollars, barrels. He made the price of oil jump up for a short while.

Funnier Fact: they had to stack all those barrels behind the corporation’s building until they could sell them all.

Does that butt have any other fun facts up there?
The roller coaster was invented during the Hundred Years’ War as a way of launching supplies across rivers.
Disclaimer: I’m stealing these
fakefun facts from other people.
Actually a oil future is basically a promise to make oil for a certain price. There are also are vegetable futures
That means the oil wasn’t produced yet
I know. I was just joshing and tossing fake facts around. 😉
But I do remember a story (on daily wtf) where a lady bought coal futures and somehow forgot or didn’t manage to sell, and a coal barge turned up in the river behind her office!
Also, Crude Barrels have a shelf life so you definitely wouldn’t store them like that for any extended period of time.
A future means that they will be created at some point in the future. Basically its an agreement to buy for a certain price in the future regardless of what the markets are doing.
Yes you said exactly that in the comment I replied to, I never argued against it I was just adding onto it. We both were talking about how unrealistic the comment further above yours was.
Well he was 69% of all traded volume… nice!!
Isn’t that wild?
This really isn’t dangerous unless you already screwed up badly. If it wipes, you just restore from backup/DR.
You do have backups and a DR plan for your prod servers, right?
Same.
Didn’t some company have a script running that would randomly kill stuff to always test redundancies?
I vaguely recall someone telling me that about netflix
that’s like starting fires on random properties to make sure your firefighters stay on their toes
Ferb, I know what we’re gonna do today
I vaguely remember reading a news story about a firefighter that did that a while ago.
Sure do! They’re on the prod servers and were one of the first things deleted!
the backup was connected via /media/backups so that’s gone too!
Not sure, do I?
I did this once on my laptop with no backups. I was lucky. I also used the correct version with --no-preserve-root.
Obligatory --no-preserve-root
Modern distros today. SMH. Back in my day everyone had root at the office.
On ye olde hpux this would work, especially when you did rm-fr /$var and $var was unset and nobody unit tested their shell back then. That db server ran for 2 days though with open file handles before it finally died.
Scene : 1998, Fort Bragg 18th Support Something-or-other, IT department
Date: 11th day of the month sometime before summer. Let’s assume May.
Young Specialist looks at wall clock. Looks at time on the system. “I can fix that!”
Should I man date first? Fuck that, let’s just do it!
Proceeds to set the time in the HP Unix minicomputer that handled all supply orders for the non Special Operations side of Fort Bragg.
Oops, set date to November 5th but with the correct time. No problem, we’ll just run that date command again and flip the 5 and the 11 around. All fixed! Back to May 11th.
Comes into work the next day wondering why everyone is running around like crazy. All the processes have kicked off and are waiting for November to run again.
Ut-oh. Comes clean to NCOIC.
Aftermath: root was taken from all junior enlisted (good move) and only Staff Sergeants and above had it l. Oh, also the outside IT professional/Army civilian I assume.
Young Specialist gets written counseling (which was bullshit BTW- I made an honest mistake) and not UCMJ supposedly because I was going off to Kuwait for PCS (Permanent Change of Station) soon. Not allowed back on system.
Disclaimer: might have happened in June but either way I’m pretty sure I set the date to November and I know I got the date command order wrong at least once.
Given that their hand is over the mouse and not the keyboard/enter key, I assume they’re gonna click close on the terminal :p
Right click for paste, they have \n in the clipboard
Afaik \n may not run a command. I have pasted multiline commands but they only seem to run after hitting enter
Depends on the terminal I think. Pretty sure KDE’s Konsole warns you that commands may be run when pasting something with newlines, but still allows it.
There is an exploit which addresses copy pasting things in terminal. Where you’d copy one thing, but when pasting you get more than you bargained for. Any decent terminal would ignore
\nfor this reason or at least not treat it as pressing enter.It definitely runs the command for me in GNOME Terminal. Pasting multiple commands at once runs everything but the last command.
Well they did have the type the command, and to do that they would first have to navigate to the terminal (assuming the machine isn’t running just a plain tty) first.
change it to
!=cowards!There is a
$[]?Huh, it’s the same as
(( ))- arithmetic expansion.
I think it’s deprecated and not in the bash manual, but it still seems to work.It is? Weird. I know about deprecated backticks, but this… I guess it’s so deprecated that very few people know about this. Now a bit more.
As an old Perl jockey, you can pry my backticks out of my cold, dead hands.
Daily Linux user since Slackware 95, news to me too lol
Same camp, and know bash very, very, well. Crazy how you can always learn.
deleted by creator
Its deprecated kinda like `` should be $() https://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xcu_chap02.html seach for arithmetic expansion or $[].
Cowards version:
[ $[ $RANDOM % 6 ] == 0 ] && echo 'rm -fr /... you crazy dude? NO' || echo 'Keep your french language pack, you will need it'
HISTCONTROL=ignorespace unset RANDOM RANDOM=4 clear ...If RANDOM is unset, it loses its special properties, even if it is subsequently reset.
HISTCONTROL If the list of values includes ignorespace, lines which begin with a space character are not saved in the history list.
RTFM can save your server AND your bet ;-)
it is cheating of course if the predefined rules tell us about such requirements and if these are not met any more when unsetting RANDOM ahead of it.
This is why you use virtual machines, anyone can be root!
Or just to have a modular, secure and private system.
We are root!
What is right clicking on terminal going to do?
maybe they have it mapped to enter, you never know with laptop linux users.
Right click increase the temp of the touchpad, which the user has macroed as an "Enter"input, letting him press enter with all fingers on home row and just resting the palm on the touch pad
Ultimate ergonomics at the cost of entry speed.
Btrfs snapshots?
You’re using btrfs on prod?!
Man, you’re crazier than I thought… /s
Oh shit that was too controversial, wasn’t it? s/btrfs/ LVM/g
Jokes on you, I use zsh, your silly bashisms have no power here.
Are you sure it doesn’t work on zsh? It’s valid POSIX shell code, and like bash, zsh is a superset of POSIX, at least if I remember correctly.
This is not to goad you into destroying your filesystem. Replace the
rmwith something relatively harmless likeecho "BANG! You're dead!"if you decide to test it.Key here is the outer [] and interaction of $[], test doesn’t have == by default in standard posix, so no this isn’t posix shell or bourne compatible. Tis but another bashism. I could probably force zsh into a more bourne mode to try it but its definitely not portable bourne shell its bash.
$ [ $[ $RANDOM % 6 ] == 0 ] && echo rm || echo ok zsh: = not found $ zsh --version zsh 5.9 (x86_64-pc-linux-gnu)== should be -eq for this to be posix/bourne portable, you could use = but -eq is for numeric comparisons so not quite right.
fish and nu are the superior shells
Is fash like that fish shell only more fetch? zsh is obviously the best, its the omega end to shell names with the z (in latin alphabets so there).
yeah i meant fish
in 2024 this should rewrite history in all your githib repos to destroy wverything next fetch
