RAR decompression method under UBUNTU (mainly to solve some problems I found recently)

RAR decompression method under UBUNTU (mainly to solve some problems I found recently)-Linux general technology-Linux technology and application information. The following is a detailed description. In UBUNTU, we have been using apt-get install rar unrar 7zip to install and decompress the tool. I didn't notice any problems.
Recently, I suddenly found that the rarfile I received in UBUNTU is often decompressed (do not blame me for not using RAR, because I have to face most other users who use WINDOWS ):
After opening some rarfiles, you can find that there are many files, but there are only two file names, that is, the first file is the current name and the second file is also the current name, however, the name of the second file is displayed from the third file, and only the first two files are obtained after decompression. I did not take the statistics too carefully. It seems that most of them are RAR compressed files containing folders (directories.
After searching, we finally found an open-source compression tool: peazip. The following is an introduction on its official website:
PeaZip free archiver utility is a portable, open source file and archive manager.
PeaZip is cross platform and runs on 32 and 64 bit Windows (9x, 2000, XP, Vista) and Linux. It supports handling implements archive and compression formats:
* Create: 7Z, ARC, BZ2, GZ, PAQ/LPAQ, PEA, QUAD, TAR, UPX, ZIP;
* Open: ACE, ARJ, CAB, DEB, ISO, LHA, RAR, RPM and more archive types...

After downloading the latest version 2.1, I directly decompress the package (my 64-bit ubuntu) and found that all the files in the RAR package I opened were okay, graphic Interface !! However, when you browse the content on the GUI, the Chinese file name in the compressed package is displayed as a question mark, but it is normal after decompression.
Now put its official website address here for everyone to share, maybe someone has encountered the same problem with me: http://peazip.sourceforge.net/

In addition, I also tested p7zip transplanted from 7zip and found that the same RAR package encountered an error: unknown suffix -- ignored (unknown suffix ), but I have installed the non-open source RAR module of p7zip. I don't know why.
If peazip exists, we will not pursue it.

Ps: This post was originally posted on the UBUNTU Chinese forum, but I posted a post on the UBUNTU Chinese forum yesterday after I found the problem, I complained for a while (because I didn't find only two solutions at the time, and I had a work error), but I just wanted to seek help, the first reply that I received was actually threatening to delete the post, because I shouldn't have said that there was a problem with LINUX, and asked if I had spent money to buy RAR, there are other posts that accuse me of not using RAR in LINUX and not using it for foreigners. I am too weak to use cloud. When I find this method and want to send it to me, I found that my post had been archived and could not be seen (it should have been deleted), so I had to send it here. The spirit of LINUX is an inclusive spirit. UBUNTU means "treating people with humanity". What makes it easy to say and do!
