Is this possible to do using grep?
General :: Burn Data (file) With Command Line (at Terminal) To DVD Rewrite?
May 17, 2010Now, I use Fedora Core (version 8) with core linux OS 2.6

Ubuntu :: Error: Allowed Memory Size Of 20971520 Bytes Exhausted (tried To Allocate 7680 Bytes) In /var/www/index.php On Line 2
Jan 9, 2011I recently had to move to a new machine, everything went well except for one thing. I did fresh installation of LAMP server all with default configs. Every time I'm using PHP script to that invokes include, require or require_once I get the following error:
Code: Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 7680 bytes) in /var/www/index.php on line 2 index.php file: PHP Code:
<?php include "index.php";?>
icukapi.php file:
PHP Code:
<?php echo "test";?>
My memory_limit in php.ini is set to 20M. I tried to increase that however it didn't quite work. PHP seems to allocate all possible space and return that message every time i try. If somebody has an idea of how to fix it I would be more than grateful. I spend quite a long time searching for an answer however the all things i found suggested increating memory_limit which in this case doesn't work.
General :: Catalina.Out File Has Binary Data After Rotate
Feb 14, 2011I manually rotated my catalina.out file, and now the file jumps to 30+Mb and when I try to view it, less tells me it might be a binary file. It sure appears to have binary data in it, about 30meg of it.
I did the rotate via a copy:
copy catalina.out to another file
cat /dev/null > catalina.out
I have tried using echo:
echo "" > catalina.out
...also with the same result.
This application isn't something I can just bounce when necessary. It kind of appears that the original file is still there - sort of. But is it not readable text anymore.

General :: Jre - RHEL-5 / Getting Error Jre-6u16-x64-rpm.bin: Line 368: ./install.sfx.20520: Cannot Execute Binary File"?
Oct 22, 2009I have installed RHEL-5 on a 64-bit machine recently, and want to install java. Earlier when I did "java -version", it showed jre1.4.0. But for my application , I need jre 1.5.0 or later, so I decided to download jre1.6. I am the root user here and I downloaded the jre1.6 as rpm.bin as well as simple .bin format.
But the problem is that when I tried executing any of them, I am getting below error message :
" ./jre-6u16-linux-x64-rpm.bin: line 368: ./install.sfx.20520: cannot execute binary file"
Moreover, now when I tried "java -version", it is not showing any thing.
Could anybody suggest me how can I resolve this deadlock situation, as I need to install my other application at the earliest.
General :: Data Recovery On HDD - Command Line Prompt
Feb 11, 2010I installed Fedora 10 on a pc I built from a barebones package, I have had no problems over the past couple months until recently. When I start up the pc the OS lags on a black screen with the cursor blinking. I have searched forums but I guess since I am a newbie I am still lost in the translations. What I am trying to do is save my files that are on the pc to a DVD-RW or my external hard drive before I have to reinstall the software again.
My questions are as follows:
How can I locate the files on the hard drive? When I have the bootable cd-rom inserted I am unable to locate the HDD. How can I transfer my files using the command line prompt? Finally, is it possible just to upgrade to the latest Fedora without losing my files and going through the data recovery process head ache? Or can I reinstall the OS and not lose my files?

Software :: Can't Prepend Subdir Name To Each File?
Jun 24, 2011To investigate an issue, I need to tarball all the files in a sub-directory without prepending the name of the subdir to each file. For instance, I do notwant tar to include MYSUBDIR:
Code:
/tmp# tar czvf package.tar.gz MYSUBDIR
MYSUBDIR/
MYSUBDIR/file1
MYSUBDIR/file2
I tried "-C MYSUBDIR", or "tar cvPf", but tar always includes the path to the files.
The only way I found is to "cd MYSUBDIR" before running "tar cvf".
Is there a way to tell tar to exlude the subdir name?
Programming :: Prepend To ASCII Text File In C?
Jun 15, 2010To start off I would like to acknowledge that I am not a very good C programmer and pretty much everything I know has been self taught through mostly trial and error. So forgive me if there is an obvious answer to my question, or if I don't immediately grasp the concepts involved in the possible solution.
Basically, I'm writing an application which will be creating log file entries rather rapidly (potentially hundreds per minute), and I would like each new line to appear at the top of the log file, rather than the end. Opening a text file in append mode is easy enough, but I can't seem to find any obvious way to do the opposite.
I have been looking online and it seems that there exists no standard way to do this, and I have only been able to find a few mentions of how somebody might achieve it. The most common method seems to be using two files and copying the data back and forth between them. This seems like it would be insanely I/O intensive with the number of lines I'm likely to be generating. If this is the best method to use, I will give it a shot; though I am not 100% clear on how to implement it, I am also open to any other ideas as to how to accomplish this, and I don't have to worry about portability since the program already uses Linux-only libraries. So calling out to sed or something is not necessarily out of the question (though I imagine performance would also be an issue there).

Jan 27, 2010I've got a Debian Squeeze computer on which the graphics have packed up, but the terminal in single user mode work perfectly fine.
There are a few files on this Debian computer that I want to transfer off, to a networked computer, but I have no idea how to do this.
The destination computer is a freshly re-setup Mandriva install, without (as yet) samba. I don't think it's necessary though. The Mandriva install works fine, has graphics, etc, but can't see the Debian Squeeze computer on the network, possibly because it's in single user mode, thus prompting the problem of how to transfer the files, using only a command line.
