0149: "Sandwich"

[Shoofle]

Being born into royalty apparently means that when you were born, your first word was SU.

[Sitnaltax]

For the uninitiated: "sudo" is the Unix-style command for "execute this command as the superuser."

[Verysillyman]

Thankyou for that, I'm not much of a programmer so it was over my head.

[posiduck]

oh man, this was a tremendously awsome installment.

I live for the geek humor.

[posiduck]

For the uninitiated: "sudo" is the Unix-style command for "execute this command as the superuser."

For the even less initiated:

It's like saying "do this as though the administrator account says to"

[Fluidfox]

I don't know if it's a good thing or a bad thing that I laughed with no hesitation upon reading this.

Scenario A: I'm a complete geek, and semi-obscure Unix/Linux humor appeals to me.

Scenario B: See scenario A.

I say "semi-obscure" because at least it's something most people who have dabbled in the forbidden fruit of Linux would -get-

One of my friends has the habit of putting sudo in front of any command that won't work. Recently it caused him to accidentally run the "delete everything from every drive" command. If only the command made sandwiches.

the worst time for me was then I meant to type

sudo rm -rf ~/foo


but instead I typed

sudo rm -rf ~/

and there went my home directory. Much of it anyways, I managed to cancel before everything had been destroyed

That's what makes this so funny. I mean, it shouldn't be funny, but for anyone whose ever been frustrated more than once by trying to do something in *NIX only to discover that it was a hidden permission problem, well, the guy in the chair's approach just seems sensible.

[Shoofle]

All this discussion is reminding me of a problem I am having. I am dabbling in making shell scripts, but when I try to run them( ./floop.sh ) it says I am not able to do that (I don't have permissions). When I try to 'sudo ./floop.sh' it gives me an error (command does not exist). Somehow I am getting around it even though su doesn't really exist in Ubuntu, but it works half the time. Anyone have any insights or ideas on what to do to get my shell scripts to run?

[rrenaud]

You probably need to change permissions (chmod) it to have the executable bit set.

Code: Select all

chmod 755 floop.sh


alternatively,

Code: Select all

chmod +x floop.sh


The first command says, make this file readable (4), writable (2), and executable (1) for me (4 + 2 + 1 = 7), and only readable and executable (4 + 1 = 5) for people in my group and the world. You can also use 777, but this will let anyone write to a file that you are going to execute, and is generally unsafe in multiuser systems.

The last command says make this executable for me, which is perhaps a lot more simple, but doesn't force you to do binary arithmetic and hence is not preferred .

[Cowie]

i never knew about sudo.. i always just did su and then did it
this comic, and the resulting thread, has been a learning experience for me.

COMPLY.

Congratulations, you just got a ln -s at Pharyngula.

[xkcd]

. . . took me a second to remember what ln does.

Yeah, that's . . . I think the third time I've been on his blog :)

ScienceBlogs actually offered to make me a full-time comicker there, but I am really enjoying xkcd here, so I stayed with the project.

This comic really needs to be put on a t-shirt. I know I would wear it to work!

One of my friends has the habit of putting sudo in front of any command that won't work. Recently it caused him to accidentally run the "delete everything from every drive" command. If only the command made sandwiches.

At my managers behest, I was asked to give one of the desktop support people sudo priveleges on an intranet server a few years back. He needed to reset the MySQL root password for a database that was only used by a few people in IT. No big deal. The machine did run the internal e-mail, web, and file services, however.

It ends up that the guy really had not worked very much with command-lines. When it came time to shut down the database he first tried:

% mysqladmin shutdown
% sudo mysqladmin shutdown
% mysql shutdown
% sudo shutdown

The first command didn't work because he didn't have -p.

I was in my office, logged into the intranet server, when I saw the 30-second "please save everything" shutdown notice. I ran to his office to see what the fuck he was doing, and found out that thankfully - you can abort the shutdown with Ctrl-C. I got it in just after the 15 second notice..

phew!

Bloody hell, how does he keep his computer together for a few months at a time?

On an semi-related note, a friend of mine once noted that the biggest security flaw in his computer was that he could type his root password whilst drunk...

[a1studmuffin]

This is quite embarassing, but I originally laughed my ass off at this comic for the wrong reason.

I thought "sudo" was referring to the sudden invasion of "sudoku" as the new hip trendy thing for people to do. I attributed the person's instant change of mind about making the sandwich to the fact that the first person added "sudo" to the front of the sentence, instantly making it a hip and trendy thing to do and that everyone is making sandwiches for me, why shouldn't you?

[Andy]

It is things like that that make me want to write a program called "ku", which requires super-user priveliges(*) to run. I have a "kunittestmodrunner" on this computer, but: "sudo kunittestmodrunner" doesn't have the same ring.

(*) Yes, I can't spell this word. Typically I google for the word to fix it up. But now that that has happened easily over 5 times, I don't think I will ever learn how. So, now I'm trying to change the spelling of the word, to something I can manage... and now google won't think less of me for misspelling a word lots of times.

Using google as a spell checker, GENIUS! Had never thought of it before but now I will be able to spell, except some of my mispellings are so obscure not even google can save me!

It is cool because it uses context too. Searching for "slashdot affect" will suggest "slashdot effect".

[Teaspoon]

Privilege becomes an easier word to spell when you realise it means "private law" - ie, to be "privileged" means to be under a custom set of laws that's different to the set the common folk have.

Once you know it's related to "legal", the second-to-last 'e' makes sense. Can't help you with remembering that it's "privi-" rather than "priva-" though.

[a1studmuffin]

I've found the problem with using Google as a spellchecker is this:

Usually if you're looking up a word in the first place, it's because it's an oddly spelled word, and lots of other people misspell it too. And because of the filthy blogs written by people who can't spell, you'll sometimes get enough hits on a misspelling that Google won't offer the alternative...

[MrBawn]

So how do you pronounce "sudo?" Does it sound like "pseudo," or "sue do?"

Incidentally, I work at Amazon, and I have this comic taped outside of my office. Except I put it there after I saw the message about it being spotted at our headquarters. Besides, this comic posted on the day I started there.

[Gelsamel]

Isn't pseudo pronounced sue-do anyway?

Either way, you might as well just say Super User Do.

...You mis-spelt /.


Gelsamel: "pseudo" ("pSOO - d'oh")
"sue do" ("soo DOO")

[Gelsamel]

I see it as Soo doe, and Soo doe.

http://dictionary.reference.com/search?r=2&q=pseudo

[MrBawn]

That's "sue do" as in "Hey Sue, could you do something for me?"

These really shouldn't be funny.

As for this whole thread: egad, I need to hurry up and get LINUXed.

ditto, my friend. i thought this was some off-the-wall sudoku reference.

Haha, me too! I was just too embarassed to say

[matrixhax0r]

So um... put this in a file called "Makefile":

Code: Select all

%:;     @touch .
whoami := $(shell whoami)
ifeq    (${whoami}, root)
me:;    @echo okay.
else
me:;    @echo what? make it yourself.
endif

And in the same folder try:

Code: Select all

$ make me a sandwich
$ sudo make me a sandwich

I'm sure someone can improve on this?

[Kin]

I'm passed an enlightened journey...all comics now make sense.


Success!

You win so very hard.

*smacks you on the head*
Now, go tell me you understand all the comics and I shall slap you with my large trout...
Anyhow, yeah, I didn't get the sudo part untill I came to the forum....

I've figured out a way to make running such commands a lot safer: When you first type it out, preface the whole thing with "#" (the comment symbol in Bash). Then make sure you've typed it correctly, and press [Home] [Delete] [Enter].

It also works for saving long commands for later that I don't want to retype. For example when I go to copy a bzImage to my boot partition, and realize almost too late that my boot partition isn't mounted yet, I comment out the long cp command, mount the partition, press the up arrow twice to recall the cp command, and run it.
