Need help with uncompressing software

I have several compressed files. I was able to open the ZIP ones with no problems, but when trying to open the RAR ones I got this error:

Reading the archive ‘filepath/archive.rar’ failed with the error ‘Failed to locate program ‘rar’ in PATH.’

After some research I came to the thought that some other program must be installed in order to open/compress RAR files. Found 2 (and I don’t know which one to install):
rar 4.0.1-1.1 from Packman
unrar 4.0.4-8.1.3 from openSUSE

Then after more forum reading I thought Ark may really not support too much formats by default and because of that several users used other uncompressors.
I remember on Windows Winrar supports several formats. Is there a Linux uncompressor with multi-format support? Or should I just install one of the 2 rar uncompressors?

Thanks for your help.

P.S: just in a quick note, and possibly offtopic from the thread, but is Firefox 9.0 working well? I’d wish to know before updating. Thanks.

This is the program you need. :slight_smile:

You need unrar.

Rar is not free, it is shareware. The uncompression algorithm was published
by the author and can be used freely, so we have unrar in openSUSE. The
full program remains shareware and is not on a repo.

The rar from packman I don’t know exactly what it contains. I doubt it is
the complete version, it could be the equivalent of rar version 1, which I
think was also published. Or perhaps it is the shareware version, dunno.

You can install several. Here instead of having a program supporting
several formats, we may have frontends that call the appropriate program
for each archive.

Thanks very much for your help.
Sorry, but what exactly is a “frontend”?
Is Unrar a different program aside from Ark, or kind of a “plugin”?

as su -

zypper in unrar

What is a frontend ? What is front end? - A Word Definition From the Webopedia Computer Dictionary

(1) For software applications, front end is the same as user interface.

(2) In client/server applications, the client part of the program is often called the front end and the server part is called the back end.

Hi,

in the context we’re talking here, Ark is a “frontend”. That means that when you double-click on a compressed file, such as the rar file you were talking about, Ark is called upon to decompress that file. Ark then presents a nice, userfriendly GUI window where you can choose what and where to decompress, and possible set other (de)compression options. However, ark itself does not contain any code that would allow it to decompress a file. Instead, Ark itself then calls upon other command line programs, such as unrar, to do the real work. You will find this kind of thing often in the Unix work, where many tools exit, but only as user UNfriendly command line programs, and then someone writes a frontend, a sort of graphical wrapper, for these tools.

I hope this was understandable.

So, as the others have stated above, do install unrar from the repositories - it’s one of the first tools I install after each new installation!

No problem here :slight_smile: Even though I use the CLI a lot, I also use frontends.
It saves time (learning), specially for not frequent tasks. Think of
ffmpeg, for instance.
