Search found two of 7zip: P7zip,p7zip-full,p7zip-rar. The study found that:
P7zip: Contains 7ZR (the smallest 7zip archive tool) and can only handle native 7z formats.
P7zip-full: Includes 7z, supports 7z, LZMA2, XZ, ZIP, CAB, GZIP, BZIP2, ARJ, TAR, CPIO, RPM, ISO, and Deb formats.
P7zip-rar: Contains a plugin that can extract RAR files.
It is recommended to install the P7zip-full package (not p7zip), as this is the most complete 7zip package and it supports many archive formats. In addition, if you want to process the RAR file, you also need to install the P7zip-rar package, the reason for a separate plug-in package is because RAR is a proprietary format. Of course, all three can be installed.
Installation:
sudo apt-get install P7zip-rar
sudo apt-get install P7zip-full
sudo apt-get install P7zip
Use:
direct command line, or compression package right-click compression/Decompression
Unfortunately, there is no GUI interface, just an extended system tool, such as the 7z format above.
More useful features can only be used on the command line.
