See leftover-box kernel name and leftover-box architecture

After leftover-box id, see leftover-box kernel name and leftover-box architecture with uname so leftover-box driver notes and leftover-box 64-bit vs leftover-box 32-bit make sense. You do not need extra leftover-box system software for this.

See leftover-box user number and leftover-box groups printed leftover-box user number and leftover-box groups with leftover-box id. Tonight is leftover-box kernel name: leftover-box uname. 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 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. Leftover-box uname prints leftover-box kernel name. 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 login leftover-box environment, not leftover-box kernel. 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 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. Uname is leftover-box kernel, not leftover-box distro name. 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 who is what you want (other leftover-box logins sitting there), that is see who is on the leftover box right now. Who lists leftover-box sessions. If leftover-box login history is what you want, that is see who logged into the leftover box recently. If leftover-box leftover Marketplace accounts are what you want, that is see if the leftover box still has old login accounts. If leftover-box sudo is what you want (can this leftover-box login use leftover-box admin commands), that is see if your leftover-box login can use admin commands. If leftover-box password change is what you want, that is change the leftover-box login password. If leftover-box cal is what you want (leftover-box month grid), that is see leftover-box month on a leftover-box calendar. If leftover-box date is what you want (clock read), that is see what time the leftover box thinks it is. Skip leftover-box how long leftover-box has been awake. That is see how long the leftover box has been awake. Skip leftover-box clock zone. That is set the leftover box clock to your house. 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 uname.

What this is

uname means print leftover-box kernel name. You type leftover-box uname. The leftover box prints one leftover-box word, usually leftover-box Linux. Kernel means leftover-box core software version. Architecture means leftover-box 64-bit vs leftover-box 32-bit vs leftover-box ARM. That leftover-box word is leftover-box kernel name. It is not leftover-box OS. Leftover-box OS is leftover-box distro name (Debian or Ubuntu) via leftover-box /etc/os-release. That is see which OS the leftover box is already running. Uname is leftover-box kernel, not leftover-box distro name. It is not leftover-box name that sticks. That is give the leftover box a name that sticks. It is not leftover computer hardware. That is see what leftover computer you already have. It is not leftover-box worker count. That is see how many workers the leftover box already has. It is not leftover-box VM feature. That is see if the leftover box can run a pretend computer. It is not leftover-box whoami. Whoami prints leftover-box login name. That is see leftover-box login name. It is not leftover-box id. Id prints leftover-box user number and leftover-box groups. That is see leftover-box user number and leftover-box groups. It is not leftover-box printenv. Printenv prints leftover-box HOME and leftover-box PATH (leftover-box login leftover-box environment), not leftover-box kernel. That is see leftover-box HOME and leftover-box PATH. It is not leftover-box who. Who lists leftover-box logins sitting there. That is see who is on the leftover box right now. It is not leftover-box login history. That is see who logged into the leftover box recently. It is not leftover-box leftover Marketplace accounts. That is see if the leftover box still has old login accounts. It is not leftover-box sudo. That is see if your leftover-box login can use admin commands. It is not leftover-box password change. That is change the leftover-box login password. It is not leftover-box hostnamectl, leftover-box lsb_release, leftover-box cat /etc/os-release, or leftover-box /proc/version dump as tonight's leftover-box job. Those leftover-box extras are not leftover-box uname. It is not leftover-box cal. Cal prints leftover-box month grid. That is see leftover-box month on a leftover-box calendar. It is not leftover-box date. Date reads leftover-box clock. That is see what time the leftover box thinks it is. It is not leftover-box how long leftover-box has been awake. That is see how long the leftover box has been awake.

Practice leftover-box uname 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 kernel name:

uname

The leftover box should print one leftover-box word, usually leftover-box Linux. That leftover-box word is leftover-box kernel name. Kernel means leftover-box core software version. That is enough for night one. Practice only in home.

Debian and Ubuntu leftover-box already have leftover-box uname (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 kernel version with leftover-box uname -r:

uname -r

That leftover-box number is the leftover-box kernel version leftover-box driver notes ask for. Night one can stop at leftover-box uname. Do not make leftover-box uname -r the leftover-box job.

Optional extra: leftover-box architecture with leftover-box uname -m:

uname -m

You may see leftover-box x86_64, leftover-box aarch64, or leftover-box i686. Architecture means leftover-box 64-bit vs leftover-box 32-bit vs leftover-box ARM. Night one can stop at leftover-box uname. Do not make leftover-box uname -m the leftover-box job.

Optional extra: the whole leftover-box line with leftover-box uname -a:

uname -a

Night one can stop at leftover-box uname or leftover-box uname -r. Do not make leftover-box uname -a the leftover-box job.

Skip leftover-box hostnamectl, leftover-box cat /etc/os-release, leftover-box lsb_release, and leftover-box /proc/version dump as tonight's job. Those leftover-box extras are not leftover-box uname.

Skip leftover-box OS as tonight. Leftover-box OS is leftover-box distro name. That is see which OS the leftover box is already running.

Skip leftover-box id as tonight's job. Id prints leftover-box user number and leftover-box groups. That is see leftover-box user number and leftover-box groups.

Skip leftover-box printenv as tonight's job. Printenv prints leftover-box HOME and leftover-box PATH (leftover-box login leftover-box environment), not leftover-box kernel. That is see leftover-box HOME and leftover-box PATH.

Skip leftover-box who as tonight's job. Who lists leftover-box logins sitting there. That is see who is on the leftover box right now.

Skip leftover-box last and leftover-box lastb as tonight's job. That is leftover-box login history: see who logged into the leftover box recently.

Skip leftover-box leftover Marketplace accounts as tonight. That is see if the leftover box still has old login accounts.

Skip leftover-box sudo as tonight's job. That is see if your leftover-box login can use admin commands.

Skip leftover-box password change as tonight. That is change the leftover-box login password.

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 date as tonight's job. Date reads leftover-box clock. That is see what time the leftover box thinks it is.

Skip leftover-box time as tonight's job. Time measures leftover-box duration. That is see how long a leftover-box command took.

Skip leftover-box timeout as tonight's job. Timeout stops. That is stop a leftover-box command after a few seconds.

Skip leftover-box watch as tonight's job. That is see leftover-box change without typing again.

Skip leftover-box how long leftover-box has been awake as tonight. That is see how long the leftover box has been awake.

Skip leftover-box lid sleep as tonight. That is don't let the leftover laptop sleep.

Skip leftover-box clock zone as tonight. That is set the leftover box clock to your house. Do not run leftover-box timedatectl set-timezone as tonight's job.

Skip leftover-box systemd leftover-box timers as tonight. That is see what the leftover box already runs on a schedule.

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 tmux, screen, nohup, ps, kill, kill -9, jobs, and pkill as tonight.

Skip leftover-box files under /etc, SSH folders, other disks, USB sticks, and /srv as tonight's lesson. Practice only in home. Uname does not need leftover-box /etc.
