Chmod Toolkit vs TrueCode

The most comprehensive Unix permissions learning tool available on any platform. Master chmod, chown, umask, ACLs, SELinux, and everything in between — then prove you know it under real exam conditions. Whether you're preparing for a Linux certification exam, hardening production servers, or learning Unix for the first time, Chmod Toolkit gives you the knowledge, the practice, and the proof. SIMULATE REAL CERTIFICATION EXAMS Three cert-specific exam modes that match actual exam methodology. Linux+ simulation: 90 questions, 90-minute timer, scaled scoring to 720/900. LPIC-1: 60 questions with fill-in-the-blank, 90 minutes, scored to 500/800. RHCSA: 18 hands-on tasks, 3 hours, reference materials available — just like the real exam. Skip, flag, and return to any question. Domain-by-domain results tell you exactly where to improve. MASTER PERMISSIONS, NOT JUST MEMORIZE THEM Spaced repetition tracks what you actually know — not what you crammed yesterday. Reviews are scheduled based on your accuracy, spending time where it matters most. Eight question types keep you sharp: multiple choice, type the octal, symbolic conversion, true/false, scenarios, fill-in-the-blank, typed commands, and multi-step task planning. PREPARE BY EXAM DOMAIN Study by exam domain for CompTIA Linux+, LPIC-1, and RHCSA. Every question maps to specific exam objectives so you know exactly what you're covering. Domain-by-domain progress tracking tells you when you're ready to test — and where to focus when you're not.
