Linux Administration

This is your bread-and-butter sysadmin skill for managing Linux boxes, whether you're provisioning production servers or debugging resource issues. It covers the essentials across Debian/Ubuntu and RHEL/CentOS: package management with apt and dnf, filesystem operations, process wrangling, cron scheduling, and log analysis with journalctl. The troubleshooting table is genuinely useful, mapping symptoms like disk full or high CPU directly to diagnostic commands and fixes. It won't teach you Linux from scratch, but if you already know your way around a terminal, it's a solid reference for the commands you use weekly but can never quite remember the flags for. The firewall sections for both ufw and firewalld are a nice touch.
