Where To Go Next

You've Covered the Core

This curriculum spans the objectives shared across CompTIA Linux+, LPIC-1, RHCSA and LFCS:

• System architecture, boot & the kernel
• Package management on both Debian and Red Hat families
• Users, groups, permissions, special bits & ACLs
• Processes, signals, priority & scheduling
• Filesystems, mounting, LVM & swap
• systemd, targets & the journal
• Networking, DNS & firewalls
• Text processing with grep/sed/awk
• Robust shell scripting
• Security: SSH, sudo, firewalls, SELinux/AppArmor
• Logging, time sync & monitoring
• Containers & virtualization fundamentals

Turn knowledge into muscle memory

Reading isn't enough for a hands-on exam. Pair each module with the matching ShellGenius labs - spin up a real container and do the tasks:

• Practice permissions & special bits in the file-permissions lab
• Practice systemd in systemd-services and service-debug
• Practice storage in mount-data-volume and disk-cleanup-crisis
• Practice scripting in bash-scripting

Final tip: Every exam rewards speed and accuracy at the shell. Do the labs until the commands are automatic.
