Suggested change
Expanded the Linux section to call out the file-permission/ownership model (chmod, chown, sudo for privileged paths) and distribution-specific package managers (apt vs dnf/yum) as the high-value Linux topics, since these are where exam scenarios and real troubleshooting actually diverge from rote command recall.
