Use case: I want to install some plymouth themes
I do "yum search plymouth"
yum show me a list of packages, that's good. But it doesn't show me wich one is already installed on my system. So i can end with ask to install packages that are already on my system. That's a waste of time and keypress...
You can try yum list *plymouth* Output will show you which packages already installed & which are not, yum list available *plymouth* will show you only not-installed packages with plymouth word in the name.
Don't sure that you can exclude installed packages from yum search.
dnf list installed
this output will show you all foo packages installed in system
whether fedora provides all packges during installation-yes or no if yes plz list packages
The system will not install a package if it's already there. How can this be a waste of time and keypresses? Surely it's quicker to do
yum install plymouth
and select 'y' when prompted than to get a list of the packages that the yum command would install, then install them all manually one by one.
If you want to see which packages will be installed by the operation, just do the yum install [package] and read down the output list for what changes are about to be applied before you confirm the install.
