Btw, people might know this already. I just learnt it couple of months ago. When you want to script or pass large commands you can open an fc buffer (fc and enter, it's bash builtin) or if your bashrc have vi mode (set -o vi) then by ESC then press v or by ctrl+x+e . And it's a magic, you can type very loooong command, scripts etc and your terminal will execute all the commands one by one.
Haha cool vid. Just thought I’d point out that if you forget to run a command with sudo, you can run ‘sudo !!’ And it will run without you having to retype it.

6Õ.~ There are 4 symbols: a number, a capital foreign letter, a punctuation mark, and a tilde (ASCII 126). In the English alphabet, there are 26 letters. With capital letters included 52 letters. When adding numbers then it makes 62 symbols. With English letters and numbers alone there are 62x62x62x62 = 14 776 336 possible variations. Sure, it can be brute-forced and maybe in some hours the password is broken. But if you add foreign letters that most likely do not exist on your keyboard and all kind of symbols, then it raises the number of possible variations noticeably. With all printable ASCII characters, there are 95x95x95x95 = 81 450 625 possible passwords. When using all possible characters in UTF-32 (2^32 = 4 294 967 296) then the number of passwords that one has to try is bigger than 3 x 10^38
@@malwaretestingfan I believe that AES-256 is still stronger than a password that consists of all possible printable Unicode symbols. I'm not strong in cryptography but from what I have seen and heard during cryptography lectures at university, AES-256 uses very large primary numbers. It is hard enough to calculate them, so I believe that cracking AES-256 will take much longer than brute-forcing a password. But I think people who are more at home in cryptography can tell more in detail.
Ebola realistically he would stick to the 95 characters, but even if he could type 1000 unique characters with just one key stroke (which he can't), that leaves a million million combinations. For simplicity, a thousand billion. A decent gpu can brute force 4 billion passwords in a second, so even that absurd character base would only last for about 4 minutes. If we use just 95 unique characters, it lasts a few milliseconds.
It should be mentioned that most of those need either root access or at least access as same account as the person who is using the computer right now. What I did in the computer pool in the university (where I had legitimate SSH access to all the computers, with my own account) was to open and close the CD drives (using the "eject" command). Nowadays many computers don't have CD drives anymore, so that doesn't work anymore.

Sometime pranks are funny; sometimes they're not; sometimes you don't even know you're doing one. Decades ago at work, we had network computers. (DOS/Word Perfect/Novell 2?, 88-ish I think.) We had also purchased some Intel? LanDesk? remote control software (a small TSR loaded after IPX network startup). We had maybe 40 computers and I was fixing the ones left on after hours. I was fixing yet another one where apparently someone had left their monitor on. I heard the next day that a clean-up worked had quit because she was working next to a "haunted computer" -- that was me connected to it remotely, typing -- and didn't want to be there anymore. I tried talking to my manager but to no avail.
