Are these multiple copies of same file with different version?

[ajaychat3]

I have recently swiched to Manjaro (June 22). When browsing through the /usr/lib on my system, I found that there are many file with similar names but appear to be of different version (different suffix). I am not sure if this is normal or my system has an issue. I move away from stable to unstable about 2 week back.
I am using manjaro unstable version with no major issues so far.

My system specs are

Operating System: Manjaro Linux
KDE Plasma Version: 5.25.4
KDE Frameworks Version: 5.97.0
Qt Version: 5.15.5
Kernel Version: 5.19.2-1-MANJARO (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz
Memory: 7.6 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620
Manufacturer: ASUSTeK COMPUTER INC.
Product Name: VivoBook S14 X430UA
System Version: 1.0

I am not facing any issue on my system as such but wanted an advice if everything is OK.

Hi @ajaychat3,

Yes, they are. AFAIK anyway.
You don’t need to worry if you’re not experiencing any issues.

Hope this helps!

Also, just FYI, you shouldn’t ever touch a file in the /usr directory as those are system files and will be overwritten on an update.

Thanks @Mirdarthos.
I have not touched any files in /usr but out curiousity was browsing the folder as to what files occupy huge space. I was relating them to Kernel version 5.15 and hence the query.

[Mirdarthos]

Curiosity is good and you should always stay curious. I just mentioned it so that you can keep it in mind in the future.

The same files are not multiple identical copies, but they are symbolic links .

Check ls to show many symbolic links

Thanks @Zesko.
Now I understand the real story.

Your size column has the arrow pointing down - click that, if the arrow points up you’ll see the bigger items at the top.

The files are marked with cog items - and there are some with a kind of square ‘link’ symbol which isn’t a file…

Make sure to check out filelight for checking out how the volume of storage is distributed.

The more interesting ones tend to be .cache folders (with Plex, I know, it can be really huge) but usually, not too much needs cleaning up.

I think arrow pointing downwards leads to decending sort order and it is correctly shown if you see the list.

Agree with you which I missed due to smaller font size.

Haha wow, that’s strange. I was bamboozled by the empty folders at the top… however, my arrow pointing UP means bigger at the top… and I never saw an app where that was different.

That is not the complete list. I just took the image of files. The folder list (truncated) is given below

Yes It is Dolphin App an inbuilt filemanager for Manjaro-KDE.

And here is the file list with arrow pointing downwards.

Reason to amuse or some thing else

I just noticed. Actually, with a ‘triangle’ or pointer, the wide end should be for larger entries - so pointing down for large files at the top makes more sense.

It seems my Dolphin - also my qBittorrent - are opposite. Not a big deal, it’s a strange inconsistency that just freaked me out…

I have now tracked it down to the application style, not only Lightly, but also Oxygen and Fusion go the opposite way.
