Terminal basics

Map the training server, learn where you are, and move through directories.

Practice absolute paths, relative paths, dot, dot-dot, and home shortcuts.

Use long and all listings to reveal dotfiles and read shell startup notes.

Run a few safe commands, review history, and clear the display without resetting state.

Use simulated manual pages to learn command intent before running tools.

Use which to understand how shells find commands.

Inspect a simulated environment without exposing real browser or server secrets.

Inspect simulated kernel, hostname, and clock output.

Use identity commands before interpreting permissions and logs.

Compare short flags and long listings in a safe directory.

Move between root, etc, and home while checking location.

Create and list a path that contains a space.

Write simple command output into a safe lab file.

See the difference between local changes and resetting the lab environment.

Use printf for predictable terminal output.

Split paths into filenames and directories.

Create and inspect a symbolic link target.

Use test to reason about files and directories.

Combine printing, tee, and reading a local note.

Review location, identity, and command memory.

Use manual pages and command paths before running unfamiliar tools.

Compare option-heavy commands without changing state.

Recover orientation after clearing output or getting lost.

Use quotes when filenames contain spaces.

Separate a command name, its options, and its target before pressing Enter.

Use help output before applying search options to a log.

Use quotes so a path containing spaces remains one argument.

Use a backslash to keep an escaped space inside one path argument.

Compare shell builtins with commands found on PATH.

Print a predictable marker, capture it, and read it back.

Resolve relative names into full canonical paths.

Build the habit of reading command guidance and current metadata first.

Reorient, review recent work, and clear the display without losing state.

Checkpoint command lookup, path resolution, output capture, and history.
