Exclude installed packages from the package lists that are proposed for emerging in Gentoo Linux?

Taking a simple example:

run the following commands in a gentoo machine with htop installed:

emerge -av htop

The system will start compilling htop package regardless whether htop has been installed or not.

What I wish to achieve is to give a parameter to emerge so that if htop is installed with the same flag, it wouldn't reinstall it.

I am on the processe of installing a software package, which gives me a huge list of packages for emerging. however, some of them have already installed. I hope this method is able to neglect the packages installed in my pc.

Thanks.

Use emerge option:

--noreplace, -n

Skips the packages specified on the command-line that have already been installed. Without this option, any package atoms or package sets you specify on the command-line will cause Portage to remerge the package, even if it is already installed. Note that Portage will not remerge dependencies by default. This option can be used to update the world file without re‐building the packages.

--selective

This is identical to the --noreplace option. Some options, such as --update (-u), --changed-use (-U), --newuse(-N), --noreplace, already imply --selective. Use --selective=n if you want to forcefully disable --selective, regardless of other options and always merge all packages
