Programming :: Open A Text File And Program Stops Working?

Feb 8, 2011

I opened a text file and read some stuff. Then I (think) I closed it. Then I tried to open another one and it stopped working. It seemed to compile fine though. Why would this be?

Code:
#include <iostream>// Libraries included
#include <string>
#include <fstream>
#include <sstream>
#include <list>

Programming :: Delete Line Of Text From Text File Via Shell?

Jan 13, 2010

I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.

Programming :: Formatting Fields And Text Being Displayed From Text File?

Feb 9, 2011

I want to display the contents of a particular log file (simple text file, I mean in Linux). But there is a problem: The contents need to be organized in a fixed format. Have a look at this log file:

sampleLog.txt

Code:

User Name: XYZ
Reported Problems Description: Blah! Blah! Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah!

[code]....

So, while displaying the contents of above file on a web page, I want to format the field names found in the log file: User Name:, Reported Problems Description:, and Remarks:. These fields may contain a variable length of text and no specific line number is assumed for them to appear on.

The desired output should look like this:

User Name: XYZ
Reported Problems Description: Blah! Blah! Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah!

[code]....

Well, what I am trying to do may sound wierd to some of you. The filed "Reported Problems Description:" can possible contain text which embeds colon (.

Ubuntu Networking :: Stops Working In 10.10 And Firefox Randomly Stops Working?

Nov 13, 2010

I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.

3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?

Programming :: Inserting Text Blob Into C Program

Aug 26, 2010

I'm writing a C program, and using Autotools. I have a large text file that I need to include verbatim, as data for my program.I used to have a hacked-together Perl script that would take a file like this: Code: A Rabbi, a Priest, and a Minister walked into a bar.The bartender said, "What is this, a joke?" I found this site that contains instructions for doing exactly what I want, but that technique requires GNU's ld, and the whole point of using Autotools in the first place is to make my project platform- and compiler-independent.I should point out that, according to the Autotools help, I can do this with a script called either "txtc.sh" or "txtc.sh.in". Unfortunately, Google can't find such a script, and it's not in any package that I can find.

Programming :: Script To Copy Paste Text From One File To Another (overwriting Part Of The File)?

Apr 19, 2011

I have a .txt-file with ~50.000 lines of numbers, generated by a mathematics program. From this file, I need line ~ 1.100 to line ~16.000 (these lines are always the same btw, this may make the solution easier, dunno) to be copy/pasted to another file, where the lines ~500 to ~15.000 (also, every time the same) should be overwritten by the aforementioned lines...I haven't found or come up with anything that works yet, mostly I find solutions to copy everything from one file to another but I can't find something to specifically overwrite a part of a file with part of another.

Ubuntu :: Open Office Writer - Lost File To Text Encoding?

Mar 3, 2011

I was working on a text file in open office writer last night, and this morning i tried to open it and a little thing popped up saying "ASCII Filter Options," prompting me for which character set, language and default fonts I wanted to use. (only after it asked if i wanted to recover the document, which i just did since it was asking me...) Now the document, which was very important, is a scrambled bunch of random characters! I cannot find the correct character set. Why is it prompting me for which character encoding I am using in the first place?

General :: Installing A .tar.gz File - How To Get A Working Program From The .tar.gz File

Apr 22, 2010

I am running Ubuntu 9.10 and had hoped to use Synaptic to find and install Truecrypt. As Synaptic couldn't find it I downloaded it from [URL]. In case it helps the file is called "truecrypt-6.3a-linux-x86.tar.gz". Apart from not knowing how to get a working program from the .tar.gz file, I don't know whether the installation process sorts out where the file should go and puts it there, or whether I have to create a directory for it and put it there myself.
