RHCSA certification training.

Shell fundamentals, redirection and pipes, grep and regular expressions, file transfer, archiving, permissions, and getting real answers out of man pages under time pressure.

Simple scripts with conditionals and loops, processing command output, and accepting input — enough to automate the repetitive half of an administrator's day.

Boot, reboot, and target selection, interrupting the boot process to reach a root shell, process management and signals, tuning profiles, and reading journal and log output to find out what actually happened.

Partitioning, physical volumes, volume groups and logical volumes, resizing, creating and mounting file systems, persistent mounts by UUID, swap, and set-GID directories and ACLs.

Scheduling with at and cron, enabling and disabling services at boot, configuring time, updating the kernel safely, and installing and managing packages and repositories.

IPv4 and IPv6 addressing, hostname resolution, static and dynamic configuration that survives a reboot, and configuring firewall rules with firewalld.

Creating and modifying local accounts and groups, password ageing, supplementary group membership, and configuring superuser access.

SELinux enforcing and permissive modes, file contexts and booleans, restoring contexts after a move, and diagnosing a denial from the audit log rather than reflexively disabling SELinux.

Finding and running container images, managing them as an unprivileged user, persistent storage for containers, and running a container as a systemd service that starts at boot.
