Another short note in the series "useful package-manager commands" 😉 . Every serious user of Linux has experienced the problem of a missing shared library when compiling the sources of a third-party program. Now, you may know that you'd need lib64xyz.so.n for a successful compilation, but you may _not_ know which (not installed!) package actually contains this particular library. I know only two package managers which would deliver this information in a straightforward way: Mandriva: urpmf Debian: wajig whichpkg (this one needs lynx and fping) In Archlinux, pacman -Qo only searches local packages, as does OpenSuse's pin. 😞 **Update 2019-04-24:** All major distributions have learned how to do that now. See my corresponding post from today.
