I often transfer files from the computer to the phone using KDE Connect. Right-click on a file in Dolphin > send to device. Many KDE apps also have a similar share button. I don't know how it works in other desktop environments.

I use a WM, not a DE, that's maybe why, anyway, I didn't see anything in the KDE connect settings.

I haven't tried but you most certainly can use

    kdeconnect-cli --share <path>

Upvoting you to increase the chance you notice my comment.

Was a bit confused by the fact that you need to input the absolute path to the file, but when I send it I can manage to find where it goes in my device.

Didn't know about that, thanks, will surely try when I reach my computer.
