Find a leftover-box file by name

After SSH works, search the leftover box for a file by name with find so you do not have to open every folder. You do not need a file manager app for this.

See what's in a leftover-box folder lists the folder you are sitting in. Find a word in a leftover-box file searches inside one file. When you forgot which folder holds the file, find walks the tree and prints matching paths. You are still only looking. The leftover box does not need a desktop, a search app, 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 already know the folder and only need the names in it, that is see what's in a leftover-box folder. If you already have the file and want one word inside it, that is find a word in a leftover-box file. If a house job broke and you need the leftover box's own diary, that is when something broke, look at the leftover-box log. 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

find walks a starting folder and prints paths whose names match what you asked for. You run it on the leftover box, after SSH. Matching paths print to the SSH window. The files stay on disk. You are only looking. It does not list only the current folder. That is ls. It does not open a file. That is cat, less, or nano. It does not search inside the file for a word. That is grep. One name pattern, same leftover box, only the matching paths.

Search a practice file

SSH in. Make a short throwaway file in a nested folder:

mkdir -p ~/practice/notes && printf 'hello\n' > ~/practice/notes/fruit.txt

Then search your home folder for that exact name:

find ~ -name 'fruit.txt'

You should see a path that ends in practice/notes/fruit.txt. That is the whole first-night trick.

Match part of a name, ignoring capital letters:

find ~ -iname '*fruit*'

The stars mean “anything before or after.” You are only looking. Do not delete the hits yet.

A real leftover-box folder that is safe to practice on:

find /etc -name 'hosts'

That file is already on Debian and Ubuntu. You are only looking. Do not edit it.

Useful extras, still looking only

Stop after the first hit when you only need one path:

find ~ -name 'fruit.txt' | head -n 1

Limit how deep the walk goes so a huge home folder stays quiet:

find ~ -maxdepth 3 -name 'fruit.txt'

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

sudo apt install findutils

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

When you are done practicing:

rm -i ~/practice/notes/fruit.txt && rmdir ~/practice/notes ~/practice

What this is not

This is not a list of the folder you are sitting in. That is see what's in a leftover-box folder. It is not a search inside a file for a word. That is find a word in a leftover-box file. It is not a dump of a short file. That is read a leftover-box file without opening the editor. It is not paging through a long file. That is read a leftover-box file one screen at a time. It is not an editor. That is edit a leftover-box file from the couch. It is not which folders are eating the disk. That is see which leftover-box folders are eating the disk. It is not a house share other computers browse. That is a folder the house can open.

What next

Need the names in one folder only? See what's in a leftover-box folder. Need to sit in the folder you found? Move into a leftover-box folder. Need only the lines with one word? Find a word in a leftover-box file. Need the last lines of a long file? See the end of a leftover-box file. Need a short file printed all at once? Read a leftover-box file without opening the editor. Need the whole long file one screen at a time? Read a leftover-box file one screen at a time. Need to change a line? Edit a leftover-box file from the couch. Need a spare before you edit? Copy a leftover-box file without leaving the box. 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 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 ls through every nested folder by hand when you forgot the path. That walk is the wrong tool for a hunt.
• Skip find / on day one. Start under ~ or one folder you trust. The whole disk is slow and noisy.
• Skip -exec rm, -delete, and any find that changes or removes files. Looking is the job today.
• Skip fancy regex, permission filters, and size filters on day one. One name pattern is enough.
• Skip buying a file manager app, a “cloud IDE,” or a NAS to find one leftover-box file by name.
• 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 SSH to the internet so you can hunt files from a coffee shop. That is keep the leftover box on the house network.
