Browse leftover-box folders then copy one file
After SSH works, browse leftover-box folders with sftp so you can pick a leftover-box file and copy it. You do not need FileZilla or a NAS for this.
Copy a file to the leftover box from your laptop moves one leftover-box file, with no leftover-box browse. Sync leftover-box files so only changes copy leftover-box folder syncs leftover-box changes. Copy a leftover-box file without leaving the box leftover-box copies on the leftover box, with no leftover-box SSH leftover-box file transfer. Download a file onto the leftover box leftover-box downloads from a leftover-box web address. See what's in a leftover-box folder and move into a leftover-box folder leftover-box list and leftover-box change leftover-box folders while you are already leftover-box SSH'd in. Tonight is leftover-box sftp: a leftover-box interactive leftover-box session so you can leftover-box ls / leftover-box cd / leftover-box get / leftover-box put, then leftover-box bye. You do not need FileZilla, WinSCP, Cyberduck, or a NAS for this.
Skip until SSH already works
SSH from the couch should already get you a leftover-box prompt. A short leftover-box name is nicer: give the leftover box a short name on your laptop so leftover-box sftp leftover is enough. If you only need one leftover-box file from the laptop with no leftover-box browse, that is copy a file to the leftover box from your laptop. If you only need leftover-box folder sync of leftover-box changes, that is sync leftover-box files so only changes copy. If you are already on the leftover box and only need a leftover-box copy there, that is copy a leftover-box file without leaving the box. If you only need a leftover-box download from a leftover-box web address, that is download a file onto the leftover box. Skip this whole note if you only need a house share other computers browse. That is a folder the house can open. Skip if you need a USB copy of the house folder. That is a backup of the leftover-box folder.
What this is
sftp means leftover-box file transfer over the same leftover-box SSH login you already have. You start leftover-box sftp leftover on the leftover-box laptop. You get a leftover-box interactive leftover-box prompt. Leftover-box ls lists leftover-box folders on the leftover box. Leftover-box cd changes leftover-box folders on the leftover box. Leftover-box get copies one leftover-box file to the leftover-box laptop. Leftover-box put copies one leftover-box file to the leftover box. Leftover-box bye leaves. It is not one leftover-box file with no leftover-box browse. That is copy a file to the leftover box from your laptop. It is not leftover-box folder sync of leftover-box changes. That is sync leftover-box files so only changes copy. It is not a leftover-box copy on the leftover box. That is copy a leftover-box file without leaving the box. It is not a leftover-box download from a leftover-box web address. That is download a file onto the leftover box. It is not leftover-box ls or leftover-box cd while you are already leftover-box SSH'd in. That is see what's in a leftover-box folder and move into a leftover-box folder. It is not a USB leftover-box backup. That is a backup of the leftover-box folder. It is not a house share other computers browse. That is a folder the house can open. It is not a careful leftover-box delete. That is delete a leftover-box file carefully.
Practice leftover-box browse from the laptop
On the leftover box first (leftover-box SSH in). Make sure leftover-box home is where you are sitting:
pwd
You want a path that ends in your login name. If not:
cd ~
Put a leftover-box practice file in leftover-box home:
echo hello > ~/sftp-me.txt
Leave that leftover-box SSH session open if you like. On the leftover-box laptop, leftover-box browse leftover-box folders over leftover-box SSH. A short leftover-box name from give the leftover box a short name on your laptop is enough:
sftp leftover
If you have no leftover-box short name yet, use the leftover-box long form from SSH from the couch:
sftp you@that-address
It may ask for the leftover-box password, or the leftover-box key passphrase, the same way leftover-box SSH does. You want a leftover-box sftp> leftover-box prompt. Inside leftover-box sftp, leftover-box list leftover-box home:
ls
You want leftover-box sftp-me.txt in that leftover-box list. Leftover-box copy that leftover-box file to the leftover-box laptop:
get sftp-me.txt
Optional leftover-box copy one leftover-box small leftover-box file the other leftover-box way, from the leftover-box laptop to leftover-box home:
put ./a-small-local.txt
Skip leftover-box put if you have no leftover-box small leftover-box local leftover-box file yet. Leftover-box leave:
bye
Check it leftover-box landed. Still on the leftover-box laptop:
ssh leftover ls ~
Or still in the leftover-box SSH session on the leftover box:
ls ~/sftp-me.txt
You want leftover-box sftp-me.txt in leftover-box home. On the leftover-box laptop you also want leftover-box sftp-me.txt in the leftover-box folder you sat in when leftover-box get ran.
Optional leftover-box aside: if you are already on the leftover box and only want leftover-box practice in leftover-box home, leftover-box sftp localhost, then leftover-box get sftp-me.txt sftp-got.txt, then leftover-box bye. Keep that leftover-box aside short. The leftover-box main leftover-box path tonight is leftover-box from the laptop, like copy a file to the leftover box from your laptop.
Optional leftover-box local leftover-box commands inside leftover-box sftp: leftover-box lls lists leftover-box files on the leftover-box laptop. Leftover-box lpwd prints the leftover-box laptop leftover-box folder. Leftover-box lcd changes leftover-box folders on the leftover-box laptop. The leftover-box l prefix means leftover-box laptop side.
If leftover-box sftp says command not found, install leftover-box OpenSSH client, then try again:
sudo apt install openssh-client
Debian and Ubuntu leftover-box laptops usually already have it. That leftover-box install is not a reason to buy FileZilla.
Useful extras, still leftover-box home only
Skip leftover-box files under leftover-box /etc, leftover-box SSH leftover-box folders, or leftover-box paths you do not own. Practice only in leftover-box home.
Skip leftover-box recursive leftover-box get -r of leftover-box whole leftover-box home as night one. Leftover-box pick one leftover-box file first.
Skip leftover-box rm inside leftover-box sftp as night one. Careful leftover-box delete only when you mean to throw leftover-box files away. That is delete a leftover-box file carefully.
Do not forward port 22. Keep leftover-box SSH on the house network: keep the leftover box on the house network.
When you are done leftover-box practicing, throw away the leftover-box practice leftover-box file. Careful leftover-box delete only. That is delete a leftover-box file carefully:
rm -i ~/sftp-me.txt
If you made leftover-box sftp-got.txt on the leftover box:
rm -i ~/sftp-got.txt
Skip leftover-box rm -rf.
What this is not
This is not one leftover-box file with no leftover-box browse. That is copy a file to the leftover box from your laptop. It is not leftover-box folder sync of leftover-box changes. That is sync leftover-box files so only changes copy. It is not a leftover-box copy on the leftover box. That is copy a leftover-box file without leaving the box. It is not a leftover-box download from a leftover-box web address. That is download a file onto the leftover box. It is not leftover-box ls or leftover-box cd while you are already leftover-box SSH'd in. That is see what's in a leftover-box folder and move into a leftover-box folder. It is not leftover-box pack for a leftover-box folder. That is pack leftover-box files into one leftover-box archive. It is not leftover-box shrink for one leftover-box file. That is shrink one leftover-box file. It is not leftover-box pieces for a leftover-box paste limit. That is split a leftover-box file into smaller leftover-box pieces. It is not a careful leftover-box delete. That is delete a leftover-box file carefully. It is not leftover-box unpack of a leftover-box zip you already have. That is unpack a leftover-box zip you already have. It is not a USB leftover-box backup. That is a backup of the leftover-box folder. It is not a house share other computers browse. That is a folder the house can open. It is not opening leftover-box SSH to the internet so you can leftover-box browse leftover-box folders from a coffee shop. That is keep the leftover box on the house network. Do not forward port 22.
