LFCS Essential Commands — Key Topics
Candidates must navigate files, edit text, manage processes, set permissions, mount storage, and configure networking using tools like ls, grep, systemctl, chmod, mount, and ip. The critical thing is correct syntax and paths, since every command runs live and errors cost points.
- Navigating and manipulating files with ls, cp, mv, rm, find and tar
- Searching and editing text using grep, sed, awk and vi
- Managing processes and jobs with ps, top, kill, systemctl
- Handling permissions, ownership, links and basic storage with chmod, chown, mount
