This is a correct recommendation, however in Debian-based distros you don't need to edit configuration files manually. Just pick some of preinstalled configs. They are installed in /usr/share/fontconfig/conf.avail and symlinked to /etc/fonts/conf.d.

And also show ls -l /etc/fonts/conf.d

It's the same across all POSIX compliant shells. zsh is not POSIX compliant.

touch a b c 'd e f' 'g h i'
for f in *; do ls -la "$f"; done

fxd

Try to avoid using any file manager (uninstall them all if it is difficult to avoid running them). So you will practice in using file manipulation commands.

Before anyone getting on about Security I don’t give 2centa about it

So Linux is not for you. Take a look at MS DOS 4.0, its sources were published few days ago.

The native directory sharing method for kvm is virtiofs. Have you tried it?

Why not use Privacy Badger to prevent usage of tracking cookies?

I recommend to throw away this drive because blocks that are readable and writeable now, may fail soon. But if you want to use it anyway, it is possible to collect a list of unaccessible blocks usong badblocks and pass it to mkfs to create a filesystem that ignores that blocks. IIRC this is described in man badblocks.

gksu and kdesu are unsupported for >10 years iirc, they were not more secure than sudo and that's one of the reasons they were abandoned. I've never heard about sux. Polkit is a bit another thing that indeed replaced them, however it does not and can not separate GUI and non-GUI processes. The process itself has to fork, drop privileges and draw a GUI after that. There's no difference between running it via sudo or pkexec, however polkit provide additional protections to prevent running unsafe apps with elevated privileges.

PAM and GVFS are not "privilege elevation frameworks" whatever you mean by this.

Idk what is bleachbit. But I know that "auth systems" can't "handle GUIs in a secure fashion". The app itself can be secure or not. By default they are not secure if they provide a GUI running in privileged process.

I know. Don't do this. Read the manual.
