Author: JacekArtymiak some free and utility of the evaluation in order to use this guide, please read the author's presentation, and then use the index to jump to guide explains you the necessary tools for that section.
If you prefer, you can read all content! we are in the back of each section provides links to reference materials, and at the end of this guide provides a main list. File compression and decompression is computing history, one of the most useful for creating, but the lack of portability and open tool is it to play its rightful role as one of the main obstacle. As long as we are with other similar UNIX users swap file, you can use such as gzip and bzip2 compress, this portable tools (links, see references). But the rest of the world who are using a variety of proprietary software--or even proprietary compression algorithm-owners may never be made public. Such developments continue to be very dangerous. Imagine in the future, we may not be able to be an important part of the decoding of files because we create them using special tools and algorithms, and the tools to run the operating system and hardware has become obsolete, disappear. This is why we should use open source compression tool, or at least use free and well documented algorithm for commercial reasons of compression tools. (Just remember to avoid using any special enhancements. This article is about the) on the Linux operating system, using .arc .arj, .lzh (.lha), .rar, .zip and .sit, .zoo file Guide. I chose to discuss these special formats because the three most popular operating system (MS-DOS, Microsoft Windows and MacOS) user most often use them. The reason I wrote this guide is to guide people to quickly find the right tools, rather than a detailed technical discussion of file compression technology. Finally, I would like to briefly explain the self extracting file. Such archives are often compressed format that contains the data of reality program. Implement them, they will unpack, and will be stored in the procedure body copy of the data contained within your specified on any drive. The only problem is that they cannot be used on Linux, no tool can extract them. In this case, you need to create archives of man as a general file compression. The current first here. I hope this guide can help you, and look forward to your comments and suggestions. Index .arc .arj .lzh (.la) .rar .zip .zoo .sit--------------------------------------------------------------------------------.arc files with .arc relatively rare. If you happen to come across one that basically can be identified it is using the old MS-DOSSAEARC or PKwarePKARC archiving utility. This form of support on Linux is not too good, and it is difficult to count on a Linux machine to extract these files. If you need to create .arc files, try to run DOSEMU or VMware or original SAEARC PKwarePKARC (in carrying the MS-DOS utility to find them on the FTP server). To unzip the file, use AladdinExpanderforLinux .arc. The time of this writing, the public Beta AladdinExpander can test purposes for free; it is to continue free was a unknown issues. To unzip the file, enter unstufffile.arc .arc. -D is a useful option, specify the destination location for the extracted files. For example: unstuff-d =./home/james/incomingfile.arc. Note: to learn more about AladdinExpanderforLinux details, read about the .sit file of that section.

Because it is an ARJ cannot get the source code of the shareware program, on the Linux platform is virtually non-existent and their functional matching tool, which makes it quite .arj files use. For ARJ file to successfully extract have been lucky enough. Not possible on Linux for .arj compressed form, because it is not used for Linux, generate this file's native compression tool. (You can try running under VMware DOSEMU or original ARJ Software, but this is not an easy-to-use solution). To unzip the file, use .arj unarj utility. Slower than ARJ, capacity as ARJ, but at least it is able to successfully extract most .arj files. It can extract the files to whenBefore the working directory, list archives, or test files. To view a brief help page, enter unarj; if you require more detailed description, see unarj.doc file, usually located/usr/doc/unarj-2.43 directory. Although where uncompressed .arj files is up to you to choose from, but to avoid confusion between the main working directory, should normally be in the home directory, create a temporary subdirectory, will change the current working directory to the new directory that will compress files to the new directory and then use unarjearchive.arj to extract the files in question. For Linux unarj can only extract all files at a time; you cannot extract individual files from a file. At least if the file already exists in the current working directory, even if found in the archive file with the same name, you will not overwrite it. In addition, unarj does not support empty directory or self extracting archives; the latter is the MS-DOS/Windows programs, they cannot be run on Linux, but you can run DOSEMU or VMware. Here are some other options: unarjarchive.arj or unarj unarjlarchive.arj--lists archives content unarjtarchive.arj--test archives unarjxarchive.arj--extract the files with pathnames, note, unarj option is not to start with a minus sign (-). If you extract the file fails, unarj try AladdinExpanderforLinux (for more information, please refer to the section .sit). You can also create archives of people make use of other tools (for example can be used for MS-DOS free gzip) to compress it. You may also need a simple.arj archives, in which you want to avoid the use of all advanced ARJ option, for example, volumes, files into small parts, as well as self extracting. Why not use the self extracting archive ARJ? these are not running under the Linux MS-DOS executable file style; they use various system libraries, their internal format is also required with Linux binary executable files of different formats. Maybe you can run DOSEMU or VMware ARJ self extracting archives. To ARJ or jar in the form of compressed still cannot be used on Linux, according to the FAQ page ARJSoftware that we shouldn't wait for Linux porting. If you know of any Linux tools can extract the .jar file, be sure to tell me. Available from the site or carry ARJSoftware you need Linux distributions of the FTP server to download unarj source code. In addition, unarj are usually basic part of Linux distributions, so you can find on the main distribution CD-ROM. If you need to all Linux distributions list of links, see Linux distributions page.

These utilities are Y.Tagawa, H.Yoshizaki, Momozou and MasaruOki development. These utilities have been ported to many operating systems, use them to create files with portability. MatsAndersson implemented Linux porting. With gzip, lha utility to perform multiple file compression. To compress a single file, enter lhaaarchivefile. Lha .lzh archives created with the extension. If archive.lzh has in the current working directory, so you let the lha compressed file will be added to the existing file. Archive.lzh previous content is still preserved, unless it already contains a file with the same name, in this case, the old files will be replaced in the new file. This operation is blind, meaning that it does not check the file's time stamp; to ensure that only with update timestamp of the file to replace the file saved in the older file, then use the u option instead of a option (for example, lhauarchivefile). When you receive .lzh files people complain when unable to decompress files, try using lhaagarchivefile or lhaaoarchivefile. G and o options respectively indicate the lha lha using conventional or and andCapacity of archiving methods. If you only update existing files, use instead of a u. Archive multiple files and archiving as easy as a single file using the wildcard character (for example, lhaaarchivefiles *) or enter the storage file is located in the top-level directory (for example, lhaaarchivedirectory). All files and subdirectories are automatically stored in the archive. File replace rules and the u option on multiple files and a single file by the same. Wildcard syntax and you commonly used shell used in the same grammar. Here are some other options: l-lha-lists archives content (for example, lhalarchive.lz) v--lists the detailed format file content (for example, lhavarchive.lz) t-test the integrity of the file (for example, lhatarchive.lz) Note, lha options do not have to take a negative sign (-) at the beginning, they also should not have spaces. If you need a list of other options, please enter .lha and .lzh la. files unzip is fairly easy: simply enter lhaearchive.lha. If the Greek
