Master Linux terminal commands by learning cd, absolute versus local pathnames, tilde, and navigating with dot and dot dot. Explore mkdir and rm with flags, and avoid syntax pitfalls.

learn to view, search, and monitor text with echo, cat, and less; search with slash, and use tail -f to watch real-time changes while handling binary files and paths.

Learn basic linux commands like ls and rm, view hidden files, list details, navigate with relative and absolute paths, and understand case sensitivity and safe naming.

View running processes and monitor CPU and memory with top. Sort by CPU, memory, or runtime and learn eject basics for CD drives and scripts that download and unpack files.

Explore Linux user management and system administration with su and sudo, switch between root and ordinary users, and safely terminate processes using kill and xkill.

Explore environment and system variables in Linux and Windows, learn how the PATH guides command lookup, how export creates terminal-local variables, and how HOME indicates home directories.

Master console text editors with Midnight Commander, nano, emacs, and vi, using two-panel navigation and practical shortcuts for saving, exiting, and safe editing in the terminal.

Vi editor: enter insert mode to edit, switch to command mode with escape, and save or exit with :w, :q, or :wq. Explore its complexity and basic shortcuts.

Explore how Linux software differs from Windows, including free, community-driven programs and diverse file formats. Learn how to install apps via source code, binary packages, and software repositories.

Explore source code distribution and manual compilation in Linux, including dependencies, configure scripts, and using GCC to build binaries. Learn the tradeoffs between source-based installation and precompiled packages.
