Save leftover-box output to a file

After SSH works, save leftover-box command output to a file with > so you can read it later. You do not need a file manager app for this.

Send leftover-box output into another command handed what the first leftover-box command printed to a second leftover-box tool. Tonight you only need one more trick: park that print in a leftover-box file. The single arrow > does that. You can keep calling it "save this." You are still only writing a practice file in home. The leftover box does not need a desktop, a file manager, or a new mini PC for this one job.

Skip until SSH already works

SSH from the couch should already get you a leftover-box prompt. If you only need to hand what one leftover-box command printed to another leftover-box tool, that is send leftover-box output into another command. If you only need to park words you typed, that is put a short line into a leftover-box file. If you only need to page a leftover-box file that already lives on disk, that is read a leftover-box file one screen at a time. 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

The single arrow > means "put what this leftover-box command printed into this leftover-box file." You type the leftover-box tool, then the arrow, then a leftover-box path. The leftover box writes that print to the leftover-box file, and the window stays quiet. The single arrow replaces whatever was already in that leftover-box file. The double arrow >> adds at the end. That is the difference from the leftover-box bar in send leftover-box output into another command. The bar hands the print to another leftover-box command. The arrow parks it in a leftover-box file. It is not words you typed. That is put a short line into a leftover-box file. It is not an editor. That is edit a leftover-box file from the couch.

Save a leftover-box list in home

SSH in. Start with a leftover-box tool you already used. ls is a safe first try:

ls > ~/names.txt

The tilde ~ is a short name for your home folder. The window stays quiet. That quiet is the leftover box writing the leftover-box list into names.txt. If that leftover-box file already had words, they are gone. That is the whole first-night trick for a leftover-box print you want to keep.

Then peek without opening the editor:

cat ~/names.txt

You want the leftover-box folder names, one per line. That is the leftover-box list, parked. That is enough for tonight.

Useful extras, still writing only

Need a few extra leftover-box lines parked too? Add them at the end with the double arrow:

seq 1 5 >> ~/names.txt

cat ~/names.txt

You want the leftover-box folder names, then 1 through 5. The double arrow >> means "add at the end." The leftover-box list you saved first is still there.

Need only matching leftover-box lines parked?

ls --help | grep -i color > ~/help-color.txt

You want a short leftover-box file of leftover-box cheat-sheet lines that mention color. The leftover-box bar hands the print to find a word in a leftover-box file. The leftover-box arrow parks that handful. Night one can mix one leftover-box bar and one leftover-box arrow when the leftover-box arrow is last.

If the leftover box says command not found for ls, seq, or cat, install the usual tools, then try again:

sudo apt install coreutils

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

When you are done practicing:

rm -i ~/names.txt

Say yes only if that leftover-box file is the leftover-box practice list. If you also made help-color.txt, delete that leftover-box file the same way.

What this is not

This is not parking leftover-box words you typed. That is put a short line into a leftover-box file. It is not handing leftover-box print to another leftover-box command. That is send leftover-box output into another command. It is not paging a leftover-box file that already lives on disk. That is read a leftover-box file one screen at a time. It is not an editor for several leftover-box lines. That is edit a leftover-box file from the couch. It is not a leftover-box copy of a leftover-box file that already exists. That is copy a leftover-box file without leaving the box. It is not a house share other computers browse. That is a folder the house can open.

What next

Need to watch leftover-box print and keep a leftover-box copy at once? Watch and save leftover-box output at once. Need to hand leftover-box print to another leftover-box tool instead of parking it? Send leftover-box output into another command. Need leftover-box words you typed, not leftover-box command print? Put a short line into a leftover-box file. Need a short dump of the leftover-box file you just saved? Read a leftover-box file without opening the editor. Need to page a leftover-box file that got long? Read a leftover-box file one screen at a time. Need only matching leftover-box lines first? Find a word in a leftover-box file. Need a line count of the leftover-box file you saved? See how long a leftover-box file is. Need the leftover-box throwaway gone for real? Delete a leftover-box file carefully. 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.

Skip

• Skip if SSH still fails. Finish SSH from the couch first.
• Skip pointing the leftover-box arrow at anything under /etc, leftover-box SSH settings, or a leftover-box file you care about. Practice only in home tonight. A single leftover-box arrow replaces the whole leftover-box file.
• Skip leftover-box error pipes and 2>&1 on night one if you only need a quiet leftover-box file. Watching the leftover-box print while you save is watch and save leftover-box output at once.
• Skip leftover-box arrows into rm, leftover-box device names, or leftover-box paths you did not just make. Practice only leftover-box tools that print, then leftover-box peek with cat.
• Skip leftover-box SSH settings, /etc/shadow, and anything under /etc/ssh. Looking at trusted laptop keys is see which laptop keys the leftover box already trusts.
• Skip opening leftover-box SSH to the internet so you can save leftover-box output from a coffee shop. That is keep the leftover box on the house network.
