Installing the deb package from compressonatorcli_4.5.52_amd64.deb from releases results in

• shell script compressonatorcli
• binary compressonatorcli-bin

.. being in /usr/, not in /usr/bin. So this is quite non-standard :), and makes them not on $PATH .

$ sudo apt install ~/Downloads/compressonatorcli_4.5.52_amd64.deb
$ dpkg -L compressonatorcli
/usr
/usr/compressonatorcli
/usr/compressonatorcli-bin
...
$ ls -Flah /usr/
total 3,9M
drwxr-xr-x 20 root root 4,0K cze 3 22:55 ./
drwxr-xr-x 24 root root 4,0K wrz 27 2025 ../

-rwxr-xr-x 1 root root 3,6M sty 30 2024 compressonatorcli-bin*
....

From a quick glance at dpkg -L compressonatorcli, maybe other files should also be in subdirectories following conventions and Filesystem Hierarchy Standard.

• /usr/documents -> should better go to /usr/share/doc/compressonatorcli/
• /usr/license/license.txt -> also to /usr/share/doc/compressonatorcli/license.txt ?
• /usr/images -> it seems these are just examples, so sthg like /usr/share/doc/compressonatorcli/example-images/
• /usr/pkglibs -> /usr/lib ?
• /usr/qt.conf -> unsure, is this necessary at all in this package?
