If you want to replicate what packages you have installed from one PC to another or for the purposes of a re-install you can use these:

Backup (list installed packages)

eopkg li | cut -d " " -f 1 | tr '\n' ' ' > ~/InstalledPackages

Copy that InstalledPackages file from your home folder to your other PC

Restore (install) packages:

sudo eopkg install $(cat InstalledPackages)

    Thank you SO much for posting those commands. They duplicate apps that used to be available to me in another distro, though I can't remember which one after all these years. In case they might be useful to others, I wrapped them into aliases that can be added to .bashrc:

    alias copyPackages="eopkg li | cut -d ' ' -f 1 | tr '\n' ' ' > ~/InstalledPackages"
    alias restorePackages='sudo eopkg install $(cat InstalledPackages)'
