Learn Linux Through Operational Challenges

Short summary

100 Days of Linux is a course that teaches Linux through 100 small operational challenges rather than isolated command lists. Each challenge frames a task with context, scope, required final state, and acceptance criteria, progressing from simple file operations to compact incident simulations. The approach builds constraint-aware habits like verifying working directories, preserving existing structures, and inspecting evidence before acting.

• •Course uses 100 sequential operational challenges instead of command lists
• •Progression spans file handoffs, permissions, services, networking, recovery, and incident simulation
• •Emphasizes constraint-aware work: verify workspace, preserve content, inspect before acting, confirm final state
