Orient on a Linux workstation
On a canned Ubuntu 24.04 LTS practice box, run six real Linux commands and read their real output shapes to recognize which tool identifies the distribution, current path, detailed file context, interface addresses, mounted-filesystem capacity, and processes. This is hands-on recognition for an Identify objective, not shell scripting, and the simulation does not inspect the learner's machine. Practice, not exam questions. Not a score predictor. Nothing taken from any exam.
The steps on this page are free to read. The hands-on lab for this procedure is included with Academy.
Steps
- 1
Run cat /etc/os-release. Read PRETTY_NAME and VERSION for the release, then ID and ID_LIKE for the distribution family.
- 2
Run pwd. Confirm that /home/rtj is an absolute current-directory path before working with relative filenames.
- 3
Run ls -la. Read the type and permission mode, link count, owner, group, size, date or time, and name, including ., .., and .bashrc.
- 4
Run ip addr. Distinguish loopback from ens33 and read link/ether plus inet, CIDR prefix, and scope.
- 5
Run df -h. Read Filesystem, Size, Used, Avail, Use%, and Mounted on to identify capacity by mounted filesystem.
- 6
Run ps aux. Read USER, PID, resource, state, time, and command columns to identify the relevant process without guessing.
What you should see
The canned console shows Ubuntu release fields, /home/rtj, a detailed listing with hidden entries, lo and ens33 address blocks, a human-readable mounted-filesystem table, and a process snapshot with systemd at PID 1, a bash shell, and ps. Output shapes are real; changing values are representative samples for this practice box.
