See what time the leftover box thinks it is

After SSH works, see what time the leftover box thinks it is with date so logs and backups make sense. You do not need a clock app for this.

See how long a leftover-box command took measured leftover-box duration with leftover-box time. Tonight is leftover-box clock read: leftover-box date. You are still only practicing in home. The leftover box does not need a clock app, 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 you only need leftover-box time (how long a leftover-box command took), that is see how long a leftover-box command took. Time measures leftover-box duration. Leftover-box date prints leftover-box clock. If leftover-box timeout is what you want (stop after a few leftover-box seconds), that is stop a leftover-box command after a few seconds. If leftover-box watch is what you want (re-run until Ctrl+C), 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 date. Skip this whole note if you only need leftover-box clock zone. That is set the leftover box clock to your house. Zone sets the city. Date reads the leftover-box clock. Skip leftover-box how long leftover-box has been awake. That is see how long the leftover box has been awake. Skip leftover-box systemd leftover-box timers. That is see what the leftover box already runs on a schedule. Skip leftover-box file date. That is see leftover-box file size, date, and permissions.

What this is

date means print what time the leftover box thinks it is right now. You type leftover-box date. The leftover box prints leftover-box day, leftover-box clock, and leftover-box zone name. That is leftover-box clock read. It is not leftover-box time. Time measures how long a leftover-box command took. That is see how long a leftover-box command took. It is not leftover-box timeout. Timeout stops. That is stop a leftover-box command after a few seconds. It is not leftover-box watch. Watch re-runs until Ctrl+C. That is see leftover-box change without typing again. It is not leftover-box clock zone. Zone sets the city with leftover-box timedatectl. That is set the leftover box clock to your house. It is not leftover-box lid sleep on a leftover laptop. That is don't let the leftover laptop sleep. It is not leftover-box file date. That is see leftover-box file size, date, and permissions. It is not how long the leftover box has been awake. That is see how long the leftover box has been awake. It is not leftover-box systemd leftover-box timers. That is see what the leftover box already runs on a schedule.

Practice leftover-box date 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 what time it thinks it is:

date

The leftover box should print leftover-box day, leftover-box clock, and leftover-box zone. Read it once. That is enough for night one. Practice only in home.

Skip leftover-box date -s and leftover-box setting the leftover-box clock by hand as night one. Night one is leftover-box read, not leftover-box set. If the leftover-box zone is wrong, that is set the leftover box clock to your house, not leftover-box date -s.

Debian and Ubuntu leftover-box usually already have leftover-box date (it comes with leftover-box coreutils). You do not install a leftover-box clock app for this.

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 UTC leftover-box clock with leftover-box -u:

date -u

UTC means Coordinated Universal Time — one shared leftover-box clock many leftover-box logs use. Night one can stay with plain leftover-box date.

Optional: leftover-box simple leftover-box format:

date '+%Y-%m-%d %H:%M:%S'

That prints leftover-box year-month-day and leftover-box hour:minute:second. Handy when leftover-box logs need a short leftover-box stamp. Skip leftover-box wild leftover-box format strings as night one.

Skip leftover-box date -s and leftover-box setting the leftover-box clock by hand as tonight's job. Night one is leftover-box read.

Skip leftover-box clock zone as tonight. That is set the leftover box clock to your house.

Skip leftover-box NTP deep dive, leftover-box BIOS clock, and leftover-box RTC hats as tonight. Night one is leftover-box date.

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 file date as tonight. That is see leftover-box file size, date, and permissions.

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.

What this is not

This is not leftover-box time. Time measures leftover-box duration. Date reads leftover-box clock. That is see how long a leftover-box command took. It is not leftover-box timeout. Timeout stops. That is stop a leftover-box command after a few seconds. It is not leftover-box watch. Watch re-runs until Ctrl+C. That is see leftover-box change without typing again. It is not leftover-box clock zone. That is set the leftover box clock to your house. It is not leftover-box lid sleep on a leftover laptop. That is don't let the leftover laptop sleep. It is not leftover-box file date. That is see leftover-box file size, date, and permissions. It is not how long the leftover box has been awake. That is see how long the leftover box has been awake. It is not leftover-box systemd leftover-box timers. That is see what the leftover box already runs on a schedule. It is not leftover-box ping as the leftover-box job. That is check that the leftover box can reach the house router. It is not leftover-box curl as the leftover-box job. That is download a file onto the leftover box. It is not a careful leftover-box delete. That is delete a leftover-box file carefully. It is not a monitoring app, htop, Grafana, or a NAS. It is not opening SSH to the internet so you can read leftover-box clock from a coffee shop. That is keep the leftover box on the house network. Do not forward port 22.

What next

Need leftover-box month grid, not leftover-box clock? See leftover-box month on a leftover-box calendar. Need leftover-box time so you know how long a leftover-box command took? See how long a leftover-box command took. Need leftover-box clock zone, not leftover-box date? Set the leftover box clock to your house. Need leftover-box timeout so a leftover-box command stops after a few leftover-box seconds? Stop a leftover-box command after a few seconds. Need leftover-box watch so a leftover-box command re-runs until Ctrl+C? See leftover-box change without typing again. Need leftover-box how long leftover-box has been awake? See how long the leftover box has been awake. Need leftover-box lid sleep on a leftover laptop? Don't let the leftover laptop sleep. Need leftover-box file date, not leftover-box clock? See leftover-box file size, date, and permissions. Need leftover-box practice files gone for real? Delete a leftover-box file carefully. When key login is boring on every computer you use, turn off leftover-box password login once the key works. Keep SSH on the house network: keep the leftover box on the house network. Do not forward port 22.
