Q: What to use when "ls" command doesn't work?

I tried to use ls command and got an error: bash: /bin/ls: cannot execute binary file what can I use instead of this command?

@Doorknob printf only seems to print the first file in a directory though..

seth@johnson ~ % mkdir test
seth@johnson ~ % cd test
seth@johnson ~/test % touch a
seth@johnson ~/test % touch b
seth@johnson ~/test % printf *
a%
seth@johnson ~/test % echo *

@muru Why? My printf does seem to support it, but I ran both in my home directory and the output was the same.

@Doorknob escapes spaces, newlines and other special characters

Doorknob

ah, didn't even know that was an option. I'll add that into my post too; thanks!

muru

Welcome. Weirdly, bash's printf builtin supports it, but the GNU printf command doesn't.

Doorknob

Huh. That's odd.

muru

One of the great mysteries of life.

But then again, if OP's ls isn't working, chances are GNU printf won't either, and the builtin's all that's around.

Mono (software)

Mono is a free and open source project led by Xamarin (formerly by Novell and originally by Ximian) to create an Ecma standard-compliant, .NET Framework-compatible set of tools including, among others, a C# compiler and a Common Language Runtime. The stated purpose of Mono is not only to be able to run Microsoft .NET applications cross-platform, but also to bring better development tools to Linux developers. Mono can be run on many software systems including Android, most Linux distributions, BSD, OS X, Windows, Solaris, and even some game consoles such as PlayStation 3, Wii, and Xbox 360. The...

kos

@Seth Sure, thanks for the willingness. It's on a shared hosting: the exploit itself it's not of interest I think, basically they managed to upload a PHP file containing a base64 encoded PHP code eventually decoded and eval'd within the script, and that's how they managed to get some type of access, altough I don't have a clear understanding of what the code does (it's pretty long, I can post it if that helps.).

However the point is they managed (I guess) to get access to the control panel I've implemented for the client, which is behing a simple login system I made.

Now the only option I can think of is they managed to perform some type of SQL injection, however I'm not able to replicate it. By now i've tried only using '*' as the username, as soon as I get back to the main machine I'll try also OR 1=1, however mysqli_query seems to take care of that (I'm using only mysqli functions).

jrg

@blade19899 Malware? Missing something.

kos

I don't know what other type of injections could there be, or if there are other options, I'm pretty inexperienced on this field. The query I run for the login is this one: SELECT * FROM utenti WHERE username="' . $username . '";

@kos OK, so rule #1 for a breach is to move production to another system, from a known good backup.

rule #2, isolate the compromised machine, then #3, dig into it.

@muru What? Why would you ever run sudo su instead of simple su or sudo -i?

I've never understood why sudo su is so common in the Ubuntu world.

muru

@kos sudo itself will clear some variables, but otherwise sudo su no better than su.

Serg

Did I miss anything in my answer ? Merely gdm lists gnome-shell as dependency but , gnome-desktop lists gdm as a recommended package, so for gnome-desktop, it's not gonna be installed.

terdon

@Serg gnome-shell is not gnome, it's only a part of gnome. Many apps depend on gnome-shell, gdm is one of them. Gnome itself doesn't depend on gdm though, why should it?

Serg

@terdon Well, that does make sense. Gnome is desktop environment, I wouldn't expect a display desktop environment to depend on some login screen.

sudo env > sudo-env

su env > su-env

Serg

wait , su env ? duh, of course it's gonna complain

terdon

@kos it gets very hard to make sense of the output when comparing too many files. I don't know of any tool that can do it.

@Serg I was looking at your and @A.B.'s answers here, well done!

Unfortunately, your NR/2 idea will break if the variables don't have an even number of fields.

For example, try:

printf ".1.3.6.1.4.1.759.2344.454545.12.1.3.6.1.4.1.759.3234.433226" | awk '{gsub("\\."," "); half=NF/2}; { for ( x=1; x<=half; x++ ) { if ( $x==$(x + half) ) printf "."$x }; printf "\n"}'

It's a neat trick but only works for even numbers of fields.

@muru that's a really cool sed solution. You might want to add an explanation though. If I understand correctly, the N saves the current line in the pattern space so the next command is applied on both lines, right?

Serg

5:18 PM

@terdon yes, I was concerned about that somewhat, but left the thought aside since OP's working with uniform numbers and requested comparison of first 7 fields. I could always add pipes to cut, so that it trims both of the numbers to appropriate lengths

terdon

@Serg He did? Where? The question asks for comparison of the entire string to extract the first N identical characters.

Serg

@terdon if you look at the comments, specifically couple last ones between kos and OP

terdon

@Serg That just says that he wants to stop comparing at the first non-identical character.

Serg

I'll just ask . . . I mean, the solution isn't universal, gonna be very specific to this case, I guess

terdon

In any case, your solution will also fail if there are three fields in one variable and 4 in the other.

I think it basically fails whenever the two strings don't have the same number of fields and the longest comes second.

Serg

5:28 PM

yup, exactly right

A.B.

Perl experts

I have matrix

how can I set @matrix[1][1]? @matrix[1][1]="foo" doesn't work

Serg

I could probably getline them into arrays, split , and then compare each array item, with for loop stepping from 1 to size of smallest array.

terdon

@A.B. use $ instead of @:

$matrix[1][1]="foo"

That's an element of an array, not an array, so you need scalar $ not the array's @

A.B.

5:44 PM

o_O

terdon

@A.B. It's the same reason why print @foo prints everything in the array @foo but print $foo[0] prints the 1st element of @foo.

@ == array

$ == scalar

So, when dealing with scalars, even if they are part of an array, you use $.

It's currently not designed to handle .lnk or symbolic links.

So either it is trying (which is a bug) or it's failing somewhere else.

So what do I do?

Nathan Osman

It can't easily follow .lnks.

Fabby

6:37 PM

Nothing? Or File bug report?

Nathan Osman

...because then you could create an infinite loop by creating a shortcut to a parent directory.

Serg

@A.B. Nah, not really. That question already has accepted answer. I'm just being obsessive about my awk code, because the idea seemed good at first, but . . .what if the two numbers aren't equal ? So I've made this code , basically I'm taking both numbers, turn them into arrays, and iterate over each element (ending is the size of the smallest array/number ) . paste.ubuntu.com/11758351

A.B.

I don't understand. It works for me

% a[6]=.1.3.6.1.4.1.232.13600256.887.1
% a[5]=.1.3.6.1.4.1.232.13600256.885.1
printf "${a[5]}${a[6]}" | ./similar
.1.3.6.1.4.1.232.13600256.1

Serg

What if the numbers are .1.3.6.1.4.1.232.13600.256.887.1 and .1.3.6.1.4.1.232.13600256.885.1 ? Then the total number of fields for two joined strings isn't even. In this case it's gonna be what, 19 ?

so I can't divide by 2

A.B.

Umpf

that's true

Serg

so I made this lengthy code, where i turn two numbers, into array, and print only similar parts. (the one in pastebin). But I'm thinking whether to post it or not

anyhows, muru's answer is already accepted, my answer covers the case of numbers of equal length, so i guess i'll stop at that

terdon

7:04 PM

@Seth Yeah, I would have probably reopened and closed again as too broad.

Seth

Good idea.

Serg

@terdon I still cannot get that awk question out of the head. I tried turning them into arrays and process with awk, but is there any way to make it simpler ?

terdon

@Serg I would probably just compare increasingly long substrings until the comparison fails.

Serg

@terdon O_O holy cow, that's right !

A.B.

Aah @Fabby, what are you doing there?

Fabby

7:18 PM

@A.B. I'm just updating links in all Questions/Answers that mention "Nitroshare" to nitroshare.net/downloads @NathanOsman

Nathan Osman

@Fabby Thanks!

And yes, the PPA is still the same.

Fabby

@Serg I'm sorry, I don't drink during the week...

(actually, I forgot to drink last week-end too!) ;-)

A.B.

forgot to drink, hmmmmmm

Serg

@Fabby Well, I'm on vacation so I guess I could cut myself some slack,right ? :D

Fabby

@Serg Hey, you're over 16 right? And that's the legal drinking age in the country you're in right now, right???

Serg

7:23 PM

@Fabby 18 is the legal age. I'm 24, in July turning 25. So I'm of legal drinking age of all the countries

unless there's some country whose legal age is like 30 o.O

Nathan Osman

@Fabby thanks for the bug report.

Fabby

@Serg When I was a kid, the legal drinking age for beer was 14...

The legal drinking age for drinking hard liquor was 16

the legal age to drive a car was 18...

Nathan Osman

We've got it the other way around.

You can drive (with supervision) as soon as 16.

Fabby

I liked it back then: teach the kids to drink first! Then teach them to drive!

Serg

@Fabby when I was 14, I also was drinking beer. But the legal age was still 18 . . . what happens in the country side, stays in the country side <.<

Fabby

7:28 PM

Nowadays it's all 18: smoking, blowing, drinking, driving...

No wonder kids die on the road!

>:)

hbdgaf

Why would anyone want to drive? That's one of the things I miss about big cities... mass transit.

Serg

Holy Aho, Weinberg and Kernighan . . . terdon just gave me a solution to a problem I was beating for 2 hours in just one sentence, no even one word. Substrings. o_o

hbdgaf

Heh, he's good for that

Serg

@Fabby kids die on the road exactly because they're drinking, driving , and blowing all at the same time. These activities have to be separated :D Although I do smoke while i drive a lot

A.B.

Q: my ubuntu server is showing high upload bandwidth,

my ubuntu server is showing high upload bandwidth, i checked with wire shark and its showing some chinese and hongkong ips. only uploading .am fed up, whats happeniing to my server, please need help

ubuntu networking

Fabby

@hbdgaf to move trailers? to fetch monthly groceries?

@Serg Yeah! That's why we used to have laws separating those... Nowadays with EU unified laws: not any more! :(

hbdgaf

I don't go out for movies and we talked about my cooking in batches, so it's easy to carry in a few bags, cook for a week and freeze half.

Serg

@hbdgaf you can cook ? that's awesome. My skills are limited to frying eggs, frying noodles, and boiling some spaghetti.

hbdgaf

@Serg Anyone can cook. It's like anything else, you just have to screw up at it a lot. The problem is eating your screw ups enough times to do it right...

Serg

@hbdgaf true. that, and also wastage of products

@terdon added version with substrings askubuntu.com/a/639551/295286

@A.B. ^

o_o awk doesn't seize to amaze me

@Fabby what's the EU unified law ?

Fabby

7:41 PM

@hbdgaf I agree completely! >:)

@Serg EU law trumps local law...

Read the Lisbon Treaty and understand how we're going down!

;-)

Serg

There's probably good aspects to it, but every country has to have some self-regulations. Like, Colorado has legalized marijuana ,but other states are still nope-ing out of it

Fabby

Hey, in the US, state law trumps Federal law!

the opposite of the EU!

That's why they're called "the United States of America" and "the European Union"

Huge basic legal difference...

I remember my history teacher in high school saying:

Forget about the USA! They were 100 years ahead of their time!

Serg

By the way, another question on the parsing of ls

Fabby

We still had Tsars and kings and emperors while the USA already had democracy!

Serg

so ls has this flag -b

A.B.

7:47 PM

@Serg Sorry =\

echo ".1.3.6.1.4.1.232.13600256.1\t.1.3.6.1.4.1.232.13600276.1" | awk 'BEGIN{i=1}{ while(substr($1,1,i)==substr($2,1,i)){var=substr($1,1,i);i++};} END{print var}'

That's wrong

.1.3.6.1.4.1.232.136002

Serg

Yup, same as my output. Prints only the things that match

Fabby

@A.B. Because he doesn't want to compete with Might God Muru??? ;-)

A.B.

^^

Serg

@Fabby I am not on that level yet to compete with muru or terdon or even Jacob Vlijm. But I am stubbornly trying :D

A.B.

@Serg Good attitude =)

@Fabby Why not :P

Serg

7:51 PM

@A.B. like seriously, when I only had just tiny amount of rep, I was looking up to muru and chili555, I didn't expect at that time I'd be like . . .here . . . even talking with higher rep users

kos

@A.B. Because it's bad :| it prints also potential matches after a non matching field

hbdgaf

@Fabby There is actually a large amount of debate and conflict over that point at the moment... think DEA shutting down smoke shops in various states that legalized some substance.

Fabby

@kos There you go! ;-)

@hbdgaf There might be a debate, but unless the constitution is altered, the DEA can only annoy people who don't know the law...

kos

@Fabby Huh? O.o

Fabby

(or are too poor to pay for expensive lawyers)

@kos I told @A.B. earlier that you didn't want to compete with Mighty God Muru!

;-)

hbdgaf

7:54 PM

@Fabby Sort of... it's a death by paperwork to fight things or reclaim anything that was seized though. Example: a fellow I know had his house raided under suspicious circumstances and never got all his belongings back. Not drug related.

A.B.

@kos paste.ubuntu.com/11758820

kos

@Fabby Yeah, I wouldn't in general, altough that particular answer came from SO!

RPi Awesomeness

You know what I would find highly amusing? If there was a non-fatal exception in Python - NonFatal Exception - NoDuh for when you state something like samevariable = samevariable.

kos

@A.B. Yeah that's the problem :( I can't find a way to force grep to exit upon the first non-match. I think it can't be done.

hbdgaf

better than returning nil

A.B.

7:58 PM

Why after the first non-match?

Serg

@kos what exactly you're trying to do ? can you link the question ?
