Linux first impressions

The podcast introduces essential Linux skills, beginning with understanding the filesystem as a master index that organizes scattered data blocks into a human-readable hierarchy. Key directories like /etc (configuration files), /var (logs and caches), /home (personal files), /bin (essential programs), /lib (shared libraries), and /usr (user-installed software) are explained. The discussion covers package management, contrasting Linux's repository-based system with Windows' installer approach, and highlights universal package formats like Snap, Flatpak, and AppImage. Progressing to the kernel, it is described as the core of the OS, managing processes, memory, and devices. The shell is presented as the command-line interpreter, translating commands for the kernel, with options like Bash and Zsh. Finally, the podcast touches on the user space, where applications and desktop environments reside, differentiating distributions like Ubuntu and Arch.
