Programming :: Regarding 7zip And Archivers In General?
Jan 26, 2011
Its much better to use the good archiver such as rar, 7zip on uncompressed files (and not after crappy zip for eg. ).People often compress .iso files and similar that contain .cab archives.So, compression ratio would be much better if those .cab files were first uncompressed and then rar-ed/7zip-ed.I know it would be difficult, and dearchiver would need to re-compress to make .cab again (so it would have to include M$ algorithm and unpacking would take a lot of time) but its possible?
How can I use 7zip/7zip CLI on an Ubuntu livecd?I would like to have the extra functions of the 7zip CLI since there are barely any options in the default Ubuntu archive manager. Some options I would like to have include setting the compression level.Would one solution be to run 7zip from an external drive?
it's my first day of trying to figure out Linux, and I now understand why it's been largely used by the geek community.I've tried to install both xcdroast and 7zip using the console and failed miserably both times.7zip doesn't have a ./configure and xcdroast just gives me errors that I don't understandI think I need a package manager?
I am trying to create a self extracting file for Windows from Ubuntu 10.04 using 7zip.
I tried these commands:
7zr -sfx7z.sfx a output.exe *.txt 7zr -sfx/usr/local/etc/7z.sfx a output.exe *.txt
Both show this error:
Error: can't find specified sfx module
System error: E_FAIL
I have all the .sfx modules on /home/username/.sfx/ because I use them previously with "rar" and it worked fine, but it's not working for 7zip. I also copied 7z.sfx to /usr/local/etc/ to test the second command like shown here but I get the same error.
i've installed the 7zip package in Fedora 15 (using Gnome3), the install was both the 'pluggin package' and the 'archiver', but i can't find how to run the program.I did open 'nautilus' file manager as a 'su' user, and found a folder 'p7zip' under usr/libexec/ location, it has three executables, 7z, 7za and 7zCon.sfxHow do i run this program, i have tried uninstalling and then re-installing the packages using both the 'Add/Remove software' manager, and using 'Yum extender', and also via the 'terminal' as an 'su' user and entering....
i'm curently compressing a big 100GB file with 7zip on a system with an intel 2,66Ghz quadcore processor. Allthough 7zip uses 4 cores to compress the file, it still uses only about 40% of the cpu performance. The cpu isn't doing anything else, nothing heavy anyway.
I started compressing 8 hours ago and the compression is currently 47% done. Reading and writing the files isn't very fast so my harddrive isn't slowing the process down.
So what's the holdup? There is still 53% of work to be done. Is it for some reason impossible to do this faster?
I have a 7zip archive and I would like to extract certain files from with it. Is there a way to do this without un-compressing the entire archive? I know these files exist in there because I am using the "7za l" command to view the files contained in the archive.

I have just given Linux a try for the first time and so far its not proving to be a good experience. I have so far just tried to install a couple of basic programs I am familiar with and ones suggested by Lifehacker.I wanted to install Tweetdeck, which meant installing Adobe Air. I duly downloaded Adobe Air but it then says I need to choose an application to open it. Assuming that the bin file was a zip file I looked in the software centre and found 7zip. Told it to load that but then couldn't find where it was. Its not listed in the Applications drop down (top right) so I found 'search for a file' and entered *7zip* to be shown 5 files. All but one appear to be a form of image file the other (7zip.desktop) isn't an exe either. Double clicking on it just gets me the following in something called gedit.
I then gave up and used google to find the program and download it, but just came across the same problem. Why oh why is there not some default program already loaded for unzipping files? How can I find 7Zip (I have already looked in the bin folder on the system drive but nothing there) and run it to tell it to make itself the default for unzipping files?
i need to write a short script that will compress a specific folder that`s on the Desktop (and all it`s content) and also will encrypt it with a password that is inside the script --->meaning it wont ask for a password+verification when compressing+encrypting
I am interested in learning 3D programming. The thing is, I would hate to put too much effort to learn something that doesn't have future and is dying. My favorite language at the time is Java. My goal is professional programming.
So I have several questions: 1. Should I learn JOGL or start learning C++ and do C++ openGL programming? 2. Is there a big difference between JOGL and C++ openGL programming? 3. Is it worth to learn openGL? Does it have a future? 4. Is it a big difference between openGL and directX coding? 5. If choosing Java, then JOGL or LWJGL?
I would like to run java program on fedora10 but I am facing some problems. When I use which java command it show usr/bin/java directory. I was trying to set the java_home path in bash_profile,but there is no affect.
I have recently been getting into kernel development and was wondering whether the Linux kernel or BSD kernel would be easiest for newbies (such as myself). Does anyone know? I am really considering BSD because it seems to me to have the best documentation.
I declared a variable as int data type which was a placeholder for a resulttatus (meaning, based on the result status that variable varies from 0/1/2/3. It can contain only these four values).data type is 4 byte integer in C#. But I can declare this variable as which represents a 1 byte integer. Since that variable contains only 1 or 2 or 3 or 4, declaring the variable asis wastage of memory space.Before declaring any variable we need to just think of the memory space needed for that variable, our requirement,
I am trying to do some shell programs. I tried some sites regarding the while loop, they give the structure as: Code: while [ n1 -lt 500 ] do echo $((n1+100)) done
But the below code also worked for me: Code: while ((n1 > 500)) do echo $((n1+100)) done By using (( )) I could use while, for. But the documentations didnt follow this way. I mainly use this for datastructure programming.
I wish to know that which gcc release version had support on ARM 9 multicore system by using pthread library for its parallelizing method on ecos rtos.I assume that the compiler that support the single ARM 9 processor will surely compile its multicore version also.But i need a clarification about it.It is good if you give a article or provide a suitable link on the ARM multicore programming and its compilation method
I am a Master's student.I am a newbie to Linux. I am interested in doing a term project in C kernel programming. I need help in developing a project in which I can use C kernel programming .
There are C, C++, Java, Perl, Python, PHP, and some other programming orand scripting languages for a Unix / Linux Distro. On a scale of 1 - 10, I rate myself on:
5 for C / C++ 5 for Java 7 for PHP 2 for Perl
When I look for a Unix job I am often asked if I know C / C++, Perl or Java. Well, they mostly look for C / C++ + Unix or Perl / Python + Unix or Java + Unix combinations. That is the trend here in India. When they advertise for C / C++ + Unix they also mean Real Time System, Kernel (Modules), and Device Drivers Development. I don't know how to do those things in C / C++. But I must say that I love C / C++ and anything else no matter how attractive or easy it could be doesn't look that much challenging to me. So, which should I take now to add to my skills set and be more productive in terms of System Administration and Application Development and Support?
In C/C++ and Java, though I know them, I don't get to work in my current job. However, I often use Shell Script (Bash) and PHP and so I am finding Perl easy because the basics of Computer Programming that I learnt by learning C and C++ and Java have made it easy for me to understand any programming language.
In our college all the systems (running on windows xp) have TURBO C/C++ installed on them which we use for C programming. I recently installed ubuntu 10.04 on me laptop (DELL Inspiron 14R (N4010) with some modifications) i read somewhere on the internet that Gedit can be used for writing a programme in ubuntu which can be compiled using gcc. Well if i use Gedit rather than Turbo c will i experience any differnce?, i mean is there any problem in doing so?? Or i should prefer running turbo c using DOS BOX?
