See leftover-box terminal name
After leftover-box locale, see leftover-box terminal name with leftover-box tty so leftover-box SSH leftover-box session vs leftover-box keyboard leftover-box session makes sense. You do not need extra leftover-box system software for this.
See leftover-box language and leftover-box region printed leftover-box language and leftover-box region with leftover-box locale. Tonight is leftover-box terminal name: leftover-box tty. Tty means leftover-box terminal name (which leftover-box session you are sitting in). Pts means leftover-box SSH leftover-box session (a pretend leftover-box terminal over the house network). You are still only practicing in home. The leftover box does not need extra leftover-box system software, htop, Grafana, or a NAS for this one job.
Skip until SSH already works
SSH from the couch should already get you a prompt. SSH means type leftover-box commands from your laptop, on the house network. If leftover-box locale is what you want (leftover-box language and leftover-box region), that is see leftover-box language and leftover-box region. Locale prints leftover-box language and leftover-box region. Leftover-box tty prints leftover-box terminal name. Skip leftover-box locale as tonight's job — that page exists. If leftover-box printenv is what you want (leftover-box HOME and leftover-box PATH), that is see leftover-box HOME and leftover-box PATH. Printenv prints leftover-box environment. Skip leftover-box printenv SSH_TTY as tonight's job — leftover-box printenv exists. If leftover-box who is what you want (leftover-box people on leftover-box sessions), that is see who is on the leftover box right now. Who lists leftover-box people. Tty prints YOUR leftover-box terminal name. Skip leftover-box who as tonight's job — that page exists. If leftover-box whoami is what you want (leftover-box login name only), that is see leftover-box login name. Whoami prints leftover-box login name. If leftover-box history is what you want, that is see who logged into the leftover box recently. Last prints leftover-box history. Skip leftover-box last as tonight's job. If leftover-box id is what you want (leftover-box user number and leftover-box groups), that is see leftover-box user number and leftover-box groups. Id prints leftover-box numbers and leftover-box groups. If leftover-box uname is what you want (leftover-box kernel name and leftover-box architecture), that is see leftover-box kernel name and leftover-box architecture. Uname prints leftover-box kernel. If leftover-box OS is what you want (Debian or Ubuntu distro name), that is see which OS the leftover box is already running. Leftover-box OS is leftover-box distro name. Tty is leftover-box terminal name, not leftover-box distro name. If leftover-box pwd is what you want (where you are sitting), that is see which leftover-box folder you are in. Pwd prints leftover-box folder path. If leftover-box which / leftover-box command -v is what you want (where one leftover-box command lives), that is see where a leftover-box command lives. If leftover-box echo is what you want (print leftover-box words you type), that is put a short line into a leftover-box file. If leftover-box help text is what you want, that is ask a leftover-box command what it does. If leftover-box name that sticks is what you want, that is give the leftover box a name that sticks. Hostname is leftover-box name on the house network. If leftover computer hardware is what you want, that is see what leftover computer you already have. If leftover-box worker count is what you want, that is see how many workers the leftover box already has. If leftover-box VM feature is what you want, that is see if the leftover box can run a pretend computer. If leftover-box date is what you want (clock read), that is see what time the leftover box thinks it is. Skip leftover-box date as tonight's job. If leftover-box clock zone is what you want, that is set the leftover box clock to your house. Skip leftover-box timezone as tonight's job. If leftover-box cal is what you want (leftover-box month grid), that is see leftover-box month on a leftover-box calendar. Skip leftover-box cal as tonight's job. Skip leftover-box how long a leftover-box command took. That is see how long a leftover-box command took. Skip leftover-box stop after a few seconds. That is stop a leftover-box command after a few seconds. Skip leftover-box re-run. That is see leftover-box change without typing again. If the leftover laptop lid is putting the leftover box to sleep, that is don't let the leftover laptop sleep. That is leftover-box lid sleep, not leftover-box tty. If leftover-box window clutter is what you want, that is clear the leftover-box window. Skip leftover-box clear as tonight's job — leftover-box clear is later. Skip leftover-box password login off as tonight's job. That is turn off leftover-box password login once the key works.
What this is
tty means print leftover-box terminal name. You type leftover-box tty. Tty means leftover-box terminal name (which leftover-box session you are sitting in). Pts means leftover-box SSH leftover-box session (a pretend leftover-box terminal over the house network). After leftover-box locale, this is leftover-box terminal name so leftover-box SSH leftover-box session vs leftover-box keyboard leftover-box session makes sense.

It is not leftover-box pts vs leftover-box tty leftover-box kernel deep dive as tonight's leftover-box job. Night one is leftover-box terminal name, not leftover-box kernel school.
Practice leftover-box tty in home
SSH in. Make sure home is where you are sitting:
pwd
You want a path that ends in your login name. If not:
cd ~
Ask the leftover box for leftover-box terminal name:
tty
The leftover box should print a leftover-box path. Expect leftover-box /dev/pts/0 from leftover-box SSH (common from the couch) or leftover-box /dev/tty1 if you are sitting at the leftover-box keyboard. Either leftover-box path is leftover-box terminal name. Tty means leftover-box terminal name. Pts means leftover-box SSH leftover-box session (a pretend leftover-box terminal over the house network). That is enough for night one. Practice only in home.
Debian and Ubuntu leftover-box already have leftover-box tty (leftover-box coreutils). Do not make leftover-box apt the leftover-box job.
No leftover-box files are required for this practice. If you made leftover-box practice files anyway, throw them away with careful delete only. That is delete a leftover-box file carefully. Skip rm -rf.
Useful extras, still home only
Optional extra: leftover-box quiet leftover-box check with leftover-box tty -s:
tty -s
Leftover-box exit 0 means leftover-box terminal is there. Night one can stop at leftover-box tty. Do not make leftover-box tty -s the leftover-box job.
Optional extra: leftover-box SSH leftover-box name with leftover-box printenv SSH_TTY:
printenv SSH_TTY
That leftover-box line is leftover-box SSH leftover-box session again (same leftover-box SSH leftover-box idea). Night one can stop at leftover-box tty. Do not make leftover-box printenv the leftover-box job — that page exists: see leftover-box HOME and leftover-box PATH. Skip leftover-box printenv SSH_TTY as the leftover-box job.
Optional extra: leftover-box people on leftover-box sessions with leftover-box who:
who
Tty prints YOUR leftover-box terminal name. Who lists leftover-box people. Night one can stop at leftover-box tty. Do not make leftover-box who the leftover-box job — that page exists: see who is on the leftover box right now.

Skip leftover-box pts vs leftover-box tty leftover-box kernel deep dive as tonight's leftover-box job. Night one is leftover-box terminal name, not leftover-box kernel school.
Skip leftover-box SSH folders, leftover-box YubiKey, leftover-box extra leftover-box system software, leftover-box camera, and leftover-box monitoring box as tonight.
Skip leftover-box cal as tonight's job. Cal prints leftover-box month grid. That is see leftover-box month on a leftover-box calendar.

Skip leftover-box clear as tonight's leftover-box job. Clear wipes leftover-box window. That is clear the leftover-box window. Skip leftover-box password login off as tonight. That is turn off leftover-box password login once the key works.
Skip leftover-box zip, tar, gzip, unzip, leftover-box du, leftover-box ping, and leftover-box curl as tonight's job. Those leftover-box pages already exist.
Skip htop, top, Grafana, a monitoring box, and a NAS. Skip leftover-box screen, leftover-box tmux, leftover-box script, leftover-box mesg, leftover-box wall, leftover-box write, nohup, ps, kill, kill -9, jobs, and pkill as tonight.
Skip leftover-box files under /etc, SSH folders, leftover-box /dev as a leftover-box dump, other disks, USB sticks, and /srv as tonight's lesson. Practice only in home. Tty does not need leftover-box /etc or leftover-box /dev as a leftover-box dump on night one.
