General :: How To Compress Files Using Zip / 7z / Rar

Jul 31, 2010

I want to package my application for linux, I use zip/tar.gz/7z/rar to do the compress in Windows.Because I do the compress in Windows, so when I extract the package in Linux, the file permission is reset.The problem is Only the tar.gz can let me extract runable files, other format (zip/7z/rar) not (the file permission is reset to 644).So my question is how to compress my files using zip/7z/rar while reset the permission to 755.

Ubuntu :: Compress Tar Files For Backups?

Oct 25, 2010

I just read in my Linux+ resources that it is not a wise idea to compress tar files with gzip if my tape drive supports compression. In addition, the resources mention that using gzip for tar files runs the risk of data lost if an error occurs with the compression.

Does anyone compress tar files for major backups/restore policies?

Ubuntu :: Compress And Encrypt Files / Folders?

Oct 30, 2010

I currently have a bash script that runs and backs up my daily files onto a separate partition using Rsync, but I thought it would be good to use the Ubuntu-one service as an ADDITIONAL backup for really important files.

How do I compress then encrypt those files, and can I add any commands that will do this to my existing bash script?

I am running Ubuntu 10.04

CentOS 5 :: Compress Files / Folders With Low Priority

Oct 23, 2009

Is there is anyway, with tar, zip, gzip, or any file compression type to compress without causing high CPU. In other words, limit how hard the CPU works to compress it? Of course I understand that this would cause the compression to take longer but time isn't too big of a concern.

General :: Compress Some Folders Containing Backup Files From Last Year?

Jul 24, 2010

Today I tried to compress some folders containing backup files from last year. I right-clicked on the folders and selected compress as tar.gz. I let it work, and found that hours later, the folders were still compressing. How long is it supposed to take, anyway? I was trying to compress the two sets of backups simultaneously; together they're around 1.5 GB. They have many subdirectories.

Software :: File Extractor (rar, 7z, Ect) For Part Files Compress By Winrar?

Apr 12, 2010

I download a lot of files that have been compressed into separate pieces by winrar, so that a 4gb file will be shown as dozen or so 93mb peices. In windows, using winrar, extracting them was rather easy but in Kubuntu whatever default program is being used throws a fit. In a perfect world I would want to get a open source alternative from synaptic, alternatively anything I can download in RPM I can eventually figure out. I want to avoid trying to get winrar working under wine.

Programming :: C++ - Two Way Communication Between Objects If A (obj) Creates An Instance Of B (obj)

I have two classes, for argument's sake A and B. A implements the core functionality, B is an encapsulated data structure. If you imagine this situation

From within B's member functions, I would like to access the public function() in class A. This is not an inheritance issue, they are two discrete classes with radically different functionality. Class A makes an object of B.

Debian Programming :: App That Creates Bootable Images For Linux

Nov 29, 2013

I'm looking for an app for Linux that creates bootable images. Back when I used windows, I used Imgburn. Now, I need an app like that for Linux. Wherever I looked online, I saw either one (or both) of these ideas.

1. Run Imgburn under wine
2. Get k3b

I don't like using wine because the programs run very slow. I'm not sure exactly how to get k3b to produce a bootable image. So that's where I'm stuck.

General :: Determine On System Where Process Substitution Creates FIFO Files?

Aug 16, 2011

I'm writing a C++ application and need to work with process substitution in the Bash shell. I'm trying to find a way to validate the paths passed as arguments to my program, some of which point to FIFO files created by process substitution.

Is there a shell (or C++) way that I can check if the system creates these files in /dev/fd or if they are created somewhere else?

Programming :: Pthread - Take String From The Command Line And Creates A Thread To Print The String

May 3, 2011

I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.


One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?

Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.

Programming :: Creates A Child Process With Fork And, When The Child Ends, Receives The SIGCHLD Signal And Wait For Its Termination?

May 23, 2011

I have a doubt about signals in C programming. I have done this little program to explain it. It creates a child process with fork and, when the child ends, receives the SIGCHLD signal and wait for its termination.Ok, quite easy, BUT when I execute this code the SIGCHLD signal is received twice, first as an error (returns -1) and the second one to finish the child process.I don't understand the meaning of the first received signal. Why is it generated? Is the code wrong? (if you add the SIGINT and press Ctrl+C during the execution it also receives two signals instead of one)

Code: #include <stdio.h>
#include <unistd.h>
#include <string.h>

Programming :: Under Which Circumstances A Child Process Creates Another Child Process Using Fork

Dec 7, 2009

Consider the following code:


int main()
int i=0;
pid_t pid;


I get the following output:

Parent: chid_pid=4356 i=0 parent's pid=4355
This is child 4356 i=0
This is child 4357 i=1


I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?
