Hook & Overview "Infographic slide titled 'From ancient roots to modern paths' on a dark background. Left side shows introductory text about the Unix file system series with three stat boxes: 4 slides, 20+ directories, 1 root. Right side shows a vertical timeline spanning 1970s to today, listing Unix classic tools, the FHS standard, and modern directories. LinuxTeck logo at bottom right. Slide counter 01/04 at top right."
Directory Tree "Infographic slide titled 'The complete directory tree at a glance' on a dark background. Displays the full Unix directory hierarchy in monospace font, starting from the root slash, with branches for bin, sbin, boot, dev, etc, home, lib, opt, proc, root, run, srv, tmp, usr, and var. Each directory has a short annotation in muted text explaining its purpose. Directory names are highlighted in blue, the root in cyan. LinuxTeck logo at bottom right. Slide counter 02/04 at top right."
Core Concepts "Infographic slide titled 'Every concept you need to understand' on a dark background. Four equal-width cards arranged in a row, each covering a core Unix concept: Everything Is a File, Absolute vs Relative Paths, Permissions and Ownership, and the Filesystem Hierarchy Standard. Each card has an emoji icon, a bold title, a description, and color-coded tag pills at the bottom. LinuxTeck logo at bottom right. Slide counter 03/04 at top right."
Series Summary "Infographic slide titled 'The complete mental model — ready to build' on a dark background. Left side lists all four slides in the series as labeled rows with colored left-border accents in cyan, orange, purple, and green. Right side shows a three-column grid of nine key Unix directories with their names in cyan monospace and brief descriptions. A green badge reading 'Ready for slide production' appears below the grid. Hashtag tags at bottom left, LinuxTeck logo at bottom right. Slide counter 04/04 at top right."
Most developers never truly understand the Unix file system and it costs them.
I remember staring at a terminal for the first time, wondering why there's no C:\ drive. No folders I recognised. Just a single mysterious /.
