In most cases, like this (using konsole as my example, no idea what the qapplication object complaint is about, but the versions are returned and konsole works just fine =:^) : $ konsole --version QCoreApplication::arguments: Please instantiate the QApplication object first Qt: 5.5.1 KDE Frameworks: 5.19.0 Konsole: 15.12.1 $ kwin_x11 --version kwin 5.5.4 (That doesn't give the frameworks or qt version, but it does give kwin version.) There are, however, some executables for which that doesn't work. Just doing an equery files plasma-desktop | grep bin (on gentoo, equery is a package manager query tool), to get the bin files in the plasma-desktop package, yields several binaries. The first one I picked, solid-action- desktop-gen (picked as it seemed reasonably obscure), yielded a version: $ solid-action-desktop-gen --version solid-action-desktop-gen 0.4 But the second one I picked, from the same bin list, kapplymousetheme, didn't: $ kapplymousetheme --version <nothing returned, except an exit status 1, indicating an error> However, kapplymousetheme, while an elf executable (not a shell script or some such), seems to be a pretty simple one, as ldd says it only links to about 10 libraries, generally generic X libs, not the several dozen including qt and kde-frameworks libs that real kde-based executables link. So it's apparently a small and simple single-purpose executable, without the usual qt and kde-frameworks linkages that more complex kde and plasma executables use. Which also explains: $ kapplymousetheme --help <nothing but an exit status of 1> Normally, kde apps will have a help output listing their own options and parameters, with two such options being --help-qt and --help-kde, which list the generic qt and kde options they inherit via the qt and kde libs. Obviously, kapplymousetheme is too small and simple for that, not inheriting the libs and thus not responding as usual to the --help option. Not too surprising, considering kapplymousetheme is under 10 KiB (10024 bytes, here), and links to so few libs. A strings run on it doesn't output a lot, either, maybe 40 lines or so, and no interesting error messages or help output of any sort, so again, pretty simple, designed for one purpose only, no user help output and likely no options, so you gotta know how to use it to use it. I guess it's designed as a helper binary to be called by the relevant kcontrol panel (aka kde system settings) applet, probably not for direct use by humans. So in general, the --version option should do it, but there are a few binaries it doesn't work on. There, simply querying your package manager to see what package the app belongs to, and what version of that you have installed, should work. Here's how it would work on gentoo, for kapplymousetheme: $ equery belongs kapplymousetheme * Searching for kapplymousetheme ... <some complaints because I don't actually have the filesystem with the packages tree in it mounted, but it can still give me an answer from the installed package database> kde-plasma/plasma-desktop-5.5.4 (/usr/bin/kapplymousetheme) So in that case the package and version is plasma-desktop 5.5.4. -- Duncan - List replies preferred.
