Will it be logical by means of Debian oriented logic to unite the three commands
apt-get clean and
apt-get autoclean, and
apt-get autoremove into one single command that does all of them?
This completely depends on what you want to achieve, they are separate for a reason. But lets see what they actually do:
apt/apt-get clean→ cleans the packages and install script in
apt/apt-get autoclean→ cleans obsolete deb-packages, less than
apt/apt-get autoremove→ removes orphaned packages which are not longer needed from the system, but not purges them, use the
--purgeoption together with the command for that.
So it is up to you to decide if you want to combine one of the first two with the last one and you can do this like below:
sudo apt autoremove && sudo apt clean
If thats what you really want to do, but now to code an extra command for it is pretty superfluous to be honest.
