Clean and remove unnecessary software from the system?

[teo]

Any application or script that does the system cleaning function and removes obsolete unnecessary software that does not use the system? And not manually with the commands pkg clean, pkg autoremove , pkg clean -a or portsclean -CDD.

How would the system be able to tell if the software is unnecessary? It can't. That's up to you. And so, it's also up to you to remove anything that's not needed.

Note that neither pkg clean or portsclean remove any installed software. The pkg-clean(8) only removes locally cached (i.e. downloaded) packages. It doesn't touch anything that's installed.

And backups do not delete by means of those commands? I understood that any dependence on older versions of unused or uninstall packages (software), the system cleaned it with those commands.

pkg-clean(8) only removes files from /var/cache/pkg/. These are locally cached files from previous invocations of pkg-install(8) or pkg-upgrade(8).

pkg-autoremove(8) will remove packages installed automatically as a dependency of another package which are not necessary anymore. The better way to keep the system clean of unnecessary packages is keeping just the packages you actually need and use as origin packages.

You can run pkg prime-list to get the origins. If there is something you don't use/need run pkg set -A1 pkgname, and then pkg autoremove to remove what is not a dependency of something.
