See leftover-box full leftover-box path

After leftover-box cmp, see leftover-box full leftover-box path with leftover-box realpath so leftover-box practice files (and leftover-box ln drills) show where leftover-box names actually live. You do not need extra leftover-box system software for this.

See whether two leftover-box files match byte for byte asked leftover-box files to leftover-box compare byte for byte with cmp ~/cmp-a.txt ~/cmp-b.txt. Tonight is leftover-box full leftover-box path: leftover-box realpath. Realpath means print leftover-box full leftover-box path. Night one prefers one tiny leftover-box practice file, then leftover-box one leftover-box shortcut, then realpath ~/realpath-a.txt and realpath ~/realpath-link.txt so leftover-box names show leftover-box where leftover-box they leftover-box live, safe peek. Leftover-box ~ is leftover-box home leftover-box shorthand. Leftover-box . is leftover-box this leftover-box folder. Leftover-box shortcut leftover-box names can leftover-box differ from leftover-box target leftover-box names. Leftover-box realpath turns leftover-box those leftover-box names into leftover-box one leftover-box full leftover-box path. That is not leftover-box pwd. Pwd prints leftover-box folder you leftover-box sit leftover-box in. That is see which leftover-box folder you are in. Skip leftover-box pwd as tonight's job — leftover-box pwd exists. That is not leftover-box ln. Ln makes leftover-box shortcut. That is make a leftover-box shortcut. Skip leftover-box ln as tonight's job — leftover-box ln exists. Tonight uses leftover-box ln -s only to leftover-box make leftover-box one leftover-box practice leftover-box shortcut. That is not leftover-box stat. Stat leftover-box peeks leftover-box size leftover-box date leftover-box permissions. That is see leftover-box file size, date, and permissions. Skip leftover-box stat as tonight's job — leftover-box stat exists. That is not leftover-box cmp. Cmp leftover-box compares leftover-box files leftover-box byte leftover-box for leftover-box byte. That is see whether two leftover-box files match byte for byte. Skip leftover-box cmp as tonight's job — leftover-box cmp exists. That is not leftover-box ls. That is see what's in a leftover-box folder. Skip leftover-box ls as tonight's job — leftover-box ls exists. That is not leftover-box find. That is find a leftover-box file by name. Skip leftover-box find as tonight's job — leftover-box find exists. Night one is leftover-box realpath on leftover-box one leftover-box tiny leftover-box home leftover-box file leftover-box and leftover-box one leftover-box shortcut. 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 cmp is what you want (leftover-box files leftover-box compared leftover-box byte leftover-box for leftover-box byte), that is see whether two leftover-box files match byte for byte. Skip leftover-box cmp as tonight's job — leftover-box cmp exists. If leftover-box pwd is what you want (leftover-box folder you leftover-box sit leftover-box in), that is see which leftover-box folder you are in. Skip leftover-box pwd as tonight's job — leftover-box pwd exists. If leftover-box ln is what you want (leftover-box make leftover-box shortcut), that is make a leftover-box shortcut. Skip leftover-box ln as tonight's job — leftover-box ln exists. Tonight uses leftover-box ln -s only to leftover-box make leftover-box one leftover-box practice leftover-box shortcut. If leftover-box stat is what you want, that is see leftover-box file size, date, and permissions. Skip leftover-box stat as tonight's job — leftover-box stat exists. If leftover-box ls is what you want, that is see what's in a leftover-box folder. Skip leftover-box ls as tonight's job — leftover-box ls exists. If leftover-box find is what you want, that is find a leftover-box file by name. Skip leftover-box find as tonight's job — leftover-box find exists. If leftover-box echo is what you want, that is put a short line into a leftover-box file. Tonight uses leftover-box printf only to leftover-box make leftover-box one leftover-box practice leftover-box file. Skip leftover-box echo as tonight's job — leftover-box echo exists. If leftover-box mkdir is what you want, that is make a leftover-box folder. Skip leftover-box mkdir as tonight's job — leftover-box mkdir exists. 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

realpath means print leftover-box full leftover-box path. You make one tiny leftover-box practice file, then leftover-box one leftover-box shortcut, then type realpath ~/realpath-a.txt and leftover-box realpath ~/realpath-link.txt. Leftover-box realpath prints leftover-box one leftover-box full leftover-box path from leftover-box first leftover-box slash to leftover-box file leftover-box name. When leftover-box name is leftover-box shortcut, leftover-box realpath follows leftover-box shortcut to leftover-box target leftover-box file. Night one prefers that safe leftover-box peek: leftover-box full leftover-box path for leftover-box file, leftover-box and leftover-box same leftover-box full leftover-box path for leftover-box shortcut. After leftover-box cmp, this is see leftover-box full leftover-box path so leftover-box practice files (and leftover-box ln drills) show where leftover-box names actually live. You do not need extra leftover-box system software for this. It is not leftover-box pwd. Pwd prints leftover-box folder you leftover-box sit leftover-box in. That is see which leftover-box folder you are in. Skip leftover-box pwd as tonight's job — leftover-box pwd exists. It is not leftover-box ln. Ln makes leftover-box shortcut. That is make a leftover-box shortcut. Skip leftover-box ln as tonight's job — leftover-box ln exists. Tonight uses leftover-box ln -s only to leftover-box make leftover-box one leftover-box practice leftover-box shortcut. It is not leftover-box stat. That is see leftover-box file size, date, and permissions. Skip leftover-box stat as tonight's job — leftover-box stat exists. It is not leftover-box cmp. Cmp leftover-box compares leftover-box files leftover-box byte leftover-box for leftover-box byte. That is see whether two leftover-box files match byte for byte. Skip leftover-box cmp as tonight's job — leftover-box cmp exists. It is not leftover-box ls. That is see what's in a leftover-box folder. Skip leftover-box ls as tonight's job — leftover-box ls exists. It is not leftover-box find. That is find a leftover-box file by name. Skip leftover-box find as tonight's job — leftover-box find exists. It is not leftover-box echo as the job. That is put a short line into a leftover-box file. Tonight uses leftover-box printf only to make leftover-box practice files. It is not leftover-box pipe as the main job. That is send leftover-box output into another command. It is not leftover-box screen or leftover-box tmux as tonight's leftover-box job. Night one is leftover-box see leftover-box full leftover-box path with leftover-box one leftover-box tiny leftover-box home leftover-box file and leftover-box one leftover-box shortcut, not leftover-box session leftover-box school.

Practice leftover-box realpath 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 ~

Make one tiny leftover-box practice file:

printf 'hello\n' > ~/realpath-a.txt

Print leftover-box full leftover-box path (night one job, leftover-box file):

realpath ~/realpath-a.txt

You want leftover-box one leftover-box full leftover-box path that ends in leftover-box realpath-a.txt, leftover-box from leftover-box first leftover-box slash. Then the prompt back. Leftover-box ~ became leftover-box full leftover-box home leftover-box path. That is enough for leftover-box file leftover-box peek.

Now make leftover-box one leftover-box shortcut:

ln -s ~/realpath-a.txt ~/realpath-link.txt

Print leftover-box full leftover-box path of leftover-box shortcut (night one job, leftover-box shortcut):

realpath ~/realpath-link.txt

You want leftover-box same leftover-box full leftover-box path ending in leftover-box realpath-a.txt, leftover-box not leftover-box shortcut leftover-box name. Then the prompt back. That is enough for night one. Practice only in home.

Debian and Ubuntu leftover-box usually already have leftover-box realpath (coreutils). Do not make leftover-box apt the job. If leftover-box realpath is somehow missing, optional aside:

sudo apt install coreutils

Then stop. That leftover-box apt line is not the leftover-box lesson.

When you are done looking, throw the leftover-box practice leftover-box names away with careful leftover-box delete only. That is delete a leftover-box file carefully. Skip rm -rf.

rm -i ~/realpath-link.txt ~/realpath-a.txt

Useful extras, still home only

Optional extra: leftover-box full leftover-box path of leftover-box this leftover-box folder:

realpath .

That peek prints leftover-box full leftover-box path of leftover-box folder you leftover-box sit leftover-box in. Do not make leftover-box . required. Night one can stay on leftover-box realpath ~/realpath-a.txt.

Optional extra: leftover-box full leftover-box path without requiring leftover-box last leftover-box name to leftover-box exist:

realpath -m ~/does-not-exist-yet.txt

That peek cleans leftover-box path leftover-box text even when leftover-box last leftover-box name is leftover-box missing. Do not make leftover-box -m required. Night one can stay on leftover-box realpath ~/realpath-a.txt.

Skip leftover-box huge leftover-box dumps as tonight's leftover-box job. Example leftover-box realpath of whole leftover-box home tree as leftover-box a leftover-box flood, leftover-box realpath of leftover-box /etc, leftover-box password leftover-box files, leftover-box disk leftover-box images, or leftover-box huge leftover-box logs, is still a huge leftover-box dump. Night one is leftover-box one leftover-box tiny leftover-box practice leftover-box file leftover-box and leftover-box one leftover-box shortcut, leftover-box not leftover-box a leftover-box giant leftover-box dump.

Skip leftover-box realpath piped into leftover-box rm as tonight's leftover-box job. Realpath prints leftover-box full leftover-box path. Rm deletes leftover-box files. Do not mix those leftover-box jobs. Careful leftover-box delete only: delete a leftover-box file carefully.

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, leftover-box whole leftover-box /, SSH folders, leftover-box /dev as a leftover-box dump, other disks, USB sticks, and /srv as tonight's lesson. Practice only in home. Realpath does not need leftover-box /etc or leftover-box / as a leftover-box dump on night one.

What this is not

This is not leftover-box pwd. Pwd prints leftover-box folder you leftover-box sit leftover-box in. Realpath leftover-box prints leftover-box full leftover-box path of leftover-box a leftover-box name leftover-box you leftover-box give leftover-box it.

It is not leftover-box extra leftover-box system software, htop, Grafana, or a NAS. It is not leftover-box /etc or leftover-box whole leftover-box /. It is not opening SSH to the internet so you can leftover-box see leftover-box full leftover-box path leftover-box from leftover-box a leftover-box coffee leftover-box shop. That is keep the leftover box on the house network. Do not forward port 22.

What next

Need leftover-box last leftover-box name from leftover-box a leftover-box path? See leftover-box last leftover-box name (basename leftover-box prints leftover-box last leftover-box name; leftover-box realpath leftover-box prints leftover-box full leftover-box path). Need leftover-box files compared byte for byte? See whether two leftover-box files match byte for byte (cmp leftover-box compares leftover-box files leftover-box byte leftover-box for leftover-box byte; leftover-box realpath leftover-box prints leftover-box full leftover-box path).
