7zip Port

[Roman Bayramdurdiyev]

Iam thinking of porting it, if there isn't one already available. Google search yielded one result, but that port was incomplete and did not compile either... If there is an already existing android port of this library, then i do not want to expend un-necessary effort on it.

If you don't want to install homebrew, you can install keka (which is an excellent gui for (un)compressing btw) and then link to the included version of p7zip found at Keka.app/Contents/Resources/keka7z

This provides an official tool which does not require any installation. The executable 7zzs can be used out of the box and is portable. It also seems to have the same syntax as p7zip (at least for simple stuff). E.g. 7zzs x archive.7z to extract. (Add it to your $PATH in order for 7zzs to work or use the full path e.g. /directory/containing/the/executable/7zzs)

The same site has the downloadable code at -zip.org/download.html. When you unpack the tarball, you will find the programs 7zz and 7zzs which you can move to /usr/local/bin. These programs are self contained and has very little dependency on other libraries.

@gbcox & @sergiomb I guess this is a silly question, but can the current package be considered complete, finished software? Fedora has basically repackaged this release on release since forever with no updates to it. that I know of there are no major issues.

I guess a side note, and this might be me being pedantic but I have seen the landscape on compression/decompression software come under a lot of attention. From forums ( Asking people to packages, include certain forks or new software ) and of course the XZ issues recently. This type of software would be a high target for how much of the OS needs, packages software all the way to user/self hosted and store files.

Yeah, I hear you. I used 7z and then moved over to xz. After the recent xz issues I just changed all my scripts, etc. to start using zstd. Why, because it appears to have much better support and is backed by a major corporation. Security and stability is my main concern, and performance definitely is good enough (some may say better).

Background:

I am doing a project in which I am benchmarking various platforms from across the 2000s using 7zip compression/decompression benchmark. I have been running Mint 19.3 XFCE 32 bit to benchmark all of the other systems but want to benchmark a system with an Athlon XP 3200+ for comparative purposes. Mint is unable to boot on this hardware, I believe because K7 is lacking support for SSE2 or some related instruction. I have gone through some attempt and failure with other distros which has led me to where I am at currently.

The problem:

I have installed Q4OS Gemini Trinity 32 bit and am writing from this machine. The installation does not seem to include 7zip preinstalled which is fine, however I am having issues when I try to install it. I have looked at another post from this forum which seems to say 7z should be preinstalled but I am not seeing this I have not had much success attempting to install it. When I try sudo apt install p7zip I get the error that the package has no installation candidate. I have tried a few different abbreviations for 7zip but cannot get anything to install. I assume I am overlooking something very simple, but need some guidance. Thanks!

The original 7-Zip is indeed available for Windows only. Its port to Linux is p7zip. I had no problem to install it on my x64 machine and it is available for i386 as well.

Did you try first to update the database of available packages?

The base package to install is p7zip. Other packages (p7zip-full and p7zip-rar) add more archive formats. Note that it is a command-line only application, no GUI is included.

Alternatively you can consider installing wine, which enables to execute Windows applications, to be able to install and run the original 7-Zip with its GUI.

If, as I suppose, you are new to linux, I encourage you to make your first steps with the "Command line interface" (CLI), i.e. using the terminal.

One valuable thing to know, is that most commands one can issue in the CLI can be used to get help on how to use them. For the p7zip command, for example, simply type after the command prompt ($)

If you prefer using a "Graphic User Interface" (GUI), you might consider using Ark. If you right-click on a zip file, Ark is likely to be an option to open it. I believe that p7zip isn't enabled by default in Ark. To enable it, in ark menu:

- Configuration > Configure Ark... > External modules

- check P7zip

Let me try to ask a desire to Q4OS Team. It would be very desirable to have a bit more apps in the application gallery, more browsers, file compressors, wine,... because on the console, not all apps work. Thank you.

Almost all applications, which are compatible with Debian Bookworm will work on Q4OS Aquarius. You can look in their websites for their compatibility with Linux Debian. For example SoftMaker FreeOffice:

Also, you can install Synaptic Package Manager from Q4OS Software Centre, and install necessary applications from Synaptic.

Just keep in mind, that nowadays, a lot of applications does not work on 32-bit hardware!

7zip is a wildly popular Windows program that is used to create archives. By default it uses 7z format which it claims is 30-70% better than the normal zip format. It also claims to compress to the regular zip format 2-10% more effectively than other zip compatible programs. It supports a wide variety of archive formats including (but not limited to) zip, gzip, bzip2, tar, and rar. Linux has had p7zip for a long time. However, this is the first time 7Zip developers have provided native Linux support.

The main reason to use the new native Linux version of 7Zip is updates. The p7zip package that comes with my Fedora installation is version 16.02 from 2016. However, the newly installed 7zip version is 21.01 (alpha) which was released just a few days ago.

7-Zip is a wonderful application designed specifically to compress and decompress files. This software allows you to extract a variety of file formats, including but not limited to 7z, XAR, ZIP, XZ, FAT, ARJ, ISO, HFS, RAR, MBR, and VHD. 7-Zip is the most secure and powerful file compression utility; therefore, it should be available on iTunes.

As far as the compatibility of 7-Zip is concerned, it is available for Windows operating systems but is also compatible with Macs. Just like many other tools, 7-Zip is programmed differently for different OS. Mac OS X does not offer native support for 7z files, but installing 7Zip for Mac can do the job.

7Zip is an incredible alternative to other file compression tools, like WinZip and WinRAR. One thing that sets 7-Zip apart is its improved security features and high compression ratio. In addition, this utility is absolutely free to use, making it a source of attraction for countless users.

Like installing 7-Zip on Windows computers, installing 7Zip for Mac is also very simple. You can use this software to extract and compress files. The two different versions of 7Zip on Mac and Windows are available. One version is command-line based, whereas the second one comes with a Graphical User Interface (GUI).

If you have never used any command line-based applications before, try benefiting from the GUI-based version of 7-Zip for Mac. On the other hand, if you are an experienced user, the command line-based version will be the most suitable option for you.

7Zip Mac comes with a wide range of amazing features, including but not limited to splitting large-sized files into smaller ones, AES-256 encryption, and multiple extraction and compression formats. In addition, self-extracting archives creation, password protection, and multi-thread processing are some more features that make 7-Zip for Mac stand out.

Now that you know how to install 7Zip for Mac. It is time to get familiar with how you can use this tool to unzip 7z files on Mac systems. The steps you need to follow to extract 7z files on Macs are listed below.

If your ZIP file carries a single file inside it, the unzipped version of this file will have the same name as the zipped file. In comparison, if your compressed file carries multiple folders and files, a new folder will be created at the time of decompression on Mac. This folder will carry all the extracted files and will be assigned the same name as the zipped file.

Have you just tried to open a ZIP file on Mac using 7-Zip or any other tool? Unable to open it correctly? It must be damaged or corrupted. This situation becomes a severe headache for those who are in need of instant extraction of compressed files. If you are going through the same situation, worry no more. Wondershare Repairit File Repair will help you repair your corrupted ZIP files in a matter of minutes.

Repairit File Repair is highly compatible with the latest Mac operating systems. It offers a free trial for novice users to determine if this tool is worth their money. As far as the premium version is concerned, you get free tech support, a money-back guarantee, and 100% safe file repair. You will need a minimum of 700 MB of free space to install Repairit on your system.

The difference between p7zip and p7zip-full is that p7zip is a lighter version providing support only for .7z while the full version provides support for more 7z compression algorithms (for audio files etc.).

You can compress a file in 7zip archive format graphically. Right-click on the file/directory, and select Compress. You should see several types of archive format options. Choose .7z for 7zip.
