Make an empty leftover-box file

After SSH works, make an empty leftover-box file with touch so nano and copies have a file to land on. You do not need a file manager app for this.

Make a leftover-box folder creates a named place. Edit a leftover-box file from the couch puts words in a file. Tonight you only need the empty file itself. touch makes that empty leftover-box file with a name you chose. You are still only making a place for later. The leftover box does not need a desktop, a file manager, or a NAS for this one job.

Skip until SSH already works

SSH from the couch should already get you a leftover-box prompt. If you need a folder first, that is make a leftover-box folder. If the file already exists and you want a spare, that is copy a leftover-box file without leaving the box. If you already have words to put in, that is edit a leftover-box file from the couch. Skip this whole note if you only need a house share other computers browse. That is a folder the house can open.

What this is

touch makes an empty leftover-box file, or leaves an existing file alone. You run it on the leftover box, after SSH. It does not make a folder. That is mkdir. It does not write a line of words. That is put a short line into a leftover-box file. It does not open an editor. That is nano. It does not copy a file that already has words. That is cp. One path, same leftover box, an empty file with a name.

Make one empty file in home

SSH in. Make an empty file you named. A short name with no spaces is easier to type later:

touch ~/hello.txt

The tilde ~ is a short name for your home folder. Swap hello.txt for a name you will remember. Letters, numbers, a hyphen, and a dot are enough. Skip spaces tonight.

Then see that it is there:

ls -lh ~/hello.txt

You want a size of zero. That is the whole first-night trick. Optional peek without opening the editor:

cat ~/hello.txt

A blank window is correct. There is nothing in it yet. Now you can put words in: edit a leftover-box file from the couch.

Useful extras, still making only

Need a leftover-box folder first? That is make a leftover-box folder. Then keep the filename and drop the empty file inside:

touch ~/notes/hello.txt

If notes is missing, make it first. touch will not invent the folder for you.

If the leftover box says command not found, install the usual tools, then try again:

sudo apt install coreutils

Debian and Ubuntu Server usually already have it. That install is not a reason to buy a file manager.

If the name already exists, a plain touch leaves the words alone and only updates the leftover box's memory of when you last touched it. That is fine for tonight. You do not need a second empty file with a stamp trick. Skip extra flags. Skip using touch to fake dates.

When you are done practicing:

rm -i ~/hello.txt

What this is not

This is not a folder. That is make a leftover-box folder. It is not an editor. That is edit a leftover-box file from the couch. It is not a copy of a file that already has words. That is copy a leftover-box file without leaving the box. It is not a dump of a file. That is read a leftover-box file without opening the editor. It is not a compare of two leftover-box files. That is see whether two leftover-box files are the same. It is not asking what kind of file this is. That is see what kind of leftover-box file this is. It is not a hunt for a file by name. That is find a leftover-box file by name. It is not a house share other computers browse. That is a folder the house can open.

What next

Need a folder for the empty file to land in? Make a leftover-box folder. Need one short line without the editor? Put a short line into a leftover-box file. Need several lines? Edit a leftover-box file from the couch. Need a spare of a file that already has words? Copy a leftover-box file without leaving the box. Need the names again? See what's in a leftover-box folder. Need a short dump after you add a line? Read a leftover-box file without opening the editor. Need to see if a spare still matches? See whether two leftover-box files are the same. Need to know if the path is text? See what kind of leftover-box file this is. Need the throwaway gone for real? Delete a leftover-box file carefully. Need a file from the laptop instead? Copy a file to the leftover box from your laptop. When a house job broke, look at the leftover box's own diary: when something broke, look at the leftover-box log. 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.

A keyboard on the leftover box is the backup now.
