A tarball when zipped using a compression algorithm forms a compressed archive. On Linux, you can find several utilities to create, extract, and manage TAR. GZ files. While the tar and gzip utility often come preinstalled on most of the distros, users will have to manually install other command-line archive managers such as 7-Zip.
The 7-Zip package is not available on official distro repositories and you won't be able to install it using the default package manager on your system. However, this doesn't mean that installing 7-Zip on a Linux machine is not possible at all. The popular file archive utility 7-Zip has been released for the Linux OS. Here's how to install it. He writes informational guides on Linux, aiming to provide a blissful experience to all newcomers. It's more like zip and rar.
Not sure what the point of using tar in conjunction with 7zip is as I haven't used 7zip myself. Exeleration-G After reading through the other answers, I see SaultDon answers this; 7zip doesn't store unix ownership and permission of the archived files it seems to be mainly geared towards Windows, like zip and rar , so it makes sense to combine it with tar to get ownership and permissions preserved.
In my experience 7z is much better at compression than zip. Eoin Yep. But the downside is that is less likely to be supported on other computers and it is quite slow. It depends on what you are looking for Compression or archiving? When I talk about archiving, I mean preserving permissions, directory structure, etc Compression may ignore most of that and just get your files in a smaller packages.
To preserve file permissions, use tar: tar cpvf backup. SaultDon SaultDon 1, 2 2 gold badges 14 14 silver badges 17 17 bronze badges. Mait Mait 1 1 silver badge 12 12 bronze badges.

But this is probably not worth the extra trouble, as it is pretty much exactly what zip files are in "one easy step". So, it will be a lot easier to use an off-the-shelf all-in-one format like zip that will allow you to extract individual files at a time.
There are many off-the-shelf libraries for extracting and manipulating files in zip archives, just start with libzip not to be confused with zlib for gzip or. Probably the biggest reason why "tar-ballz" are so popular and famously used in Unix-like systems is that they preserve file permissions and other meta-data, I guess. I think that some implementations of zip and 7z might provide that feature as an extension to the format, but most don't have it. The convenient thing with tar archives is that whatever you put in there comes out exactly the same at the other end, with all permissions and whatever else preserved.
And the "gzip" compression from zlib has just been historically an industry-standard compression algorithm, although, now, there are better ones, also supported by tar, such as. There aren't really that many other formats. The point is that you won't really find much that is better than zip or 7z. And their competitors are more or less gone today like rar? No, use zip or 7z.
Tar-balls are for backups. They are optimized for that purpose e. For your application, zip or 7z is more appropriate. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Mehrad - also, I don't know what kind of problems do you encounter when unzipping untar a 1gig tar. I've done that many times, up to 2GB with older installs of gzip and up to 4gb with newer versions of gzip. If you are doing it over the wire or on a NFS mount, then duh! You'll encounter similar performances problems as if done with plain zip. Heck, I've even untarred from a pipe to a remote process spitting gzip input into a socket.
Try that with zip. For each problem, use the appropriate tool be it tar gz or zip. ZIP files put all the file info in a unified header, then all the file contents Community Bot 1. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name.
