Pull one leftover-box column

After SSH works, pull one leftover-box column with cut so a mixed leftover-box line is easier to scan. You do not need a file manager app for this.

Drop leftover-box duplicate lines kept one of each leftover-box line. Tonight you only need one more trick: pull one leftover-box column so a mixed leftover-box line is easier to scan. cut does that. leftover-box -d, is leftover-box comma. leftover-box -f1 is leftover-box column one. You are still only looking. 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 leftover-box copies dropped, that is drop leftover-box duplicate lines. If you only need leftover-box lines in A-to-Z order, that is put leftover-box lines in order. If you only need leftover-box print handed to another leftover-box tool, that is send leftover-box output into another command. If you only need leftover-box words you typed, that is put a short line into a leftover-box file. 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

cut means "pull one leftover-box column." You type leftover-box cut, leftover-box -d,, leftover-box -f1, and a leftover-box file. leftover-box -d is leftover-box delimiter: the leftover-box character that splits leftover-box columns. leftover-box comma is the leftover-box split tonight. leftover-box -f1 is leftover-box field 1: the leftover-box column before the leftover-box comma. The leftover box prints that leftover-box column. It does not rewrite the leftover-box file unless you ask it to. It is not leftover-box search. That is find a word in a leftover-box file. It is not leftover-box order. That is put leftover-box lines in order. It is not leftover-box copies dropped. That is drop leftover-box duplicate lines. It is not leftover-box first leftover-box lines. That is see the start of a leftover-box file. It is not leftover-box last leftover-box lines. That is see the end of a leftover-box file. It is not leftover-box whole dump. That is read a leftover-box file without opening the editor.

Pull one leftover-box column from a practice file

SSH in. Make a tiny leftover-box comma file in leftover-box home:

printf 'apple,red\nbanana,yellow\npear,green\n' > ~/fruit.csv

That leftover-box save is save leftover-box output to a file. Peek first:

cat ~/fruit.csv

You want apple,red, then banana,yellow, then pear,green. Now pull leftover-box field 1, the leftover-box fruit:

cut -d, -f1 ~/fruit.csv

You want apple, then banana, then pear. leftover-box -d, is leftover-box comma. leftover-box -f1 is leftover-box column one. The leftover-box file on disk is still the mixed leftover-box comma lines. That is the whole first-night trick: leftover-box columns in a leftover-box window, leftover-box file left alone.

Need leftover-box colors instead?

cut -d, -f2 ~/fruit.csv

You want red, then yellow, then green. leftover-box -f2 is leftover-box column two.

Useful extras, still looking only

Need leftover-box fruit and leftover-box color together?

cut -d, -f1,2 ~/fruit.csv

You want the same leftover-box comma lines back. leftover-box -f1,2 means leftover-box field 1 and leftover-box field 2.

Need leftover-box first leftover-box letters only, not leftover-box columns?

cut -c1-5 ~/fruit.csv

You want apple, then banan, then pear,. leftover-box -c means leftover-box characters: leftover-box letters counted from the leftover-box start of the leftover-box line, leftover-box commas too. leftover-box 1-5 is leftover-box letters 1 through 5. That leftover-box look is optional.

Need leftover-box first leftover-box letters from leftover-box folder names, without a leftover-box file in the middle?

ls | cut -c1-4

You want leftover-box first leftover-box letters from leftover-box names. That leftover-box bar is send leftover-box output into another command. Looking only. Skip leftover-box ls -lh piped into leftover-box cut. leftover-box ls -lh pads leftover-box spaces, and leftover-box cut -d' ' splits on leftover-box one leftover-box space, so leftover-box columns land in leftover-box wrong leftover-box fields. That leftover-box trap is not leftover-box night one.

Skip leftover-box sort then leftover-box uniq then leftover-box cut on leftover-box night one. leftover-box cut by itself is enough for leftover-box first leftover-box look.

If the leftover box says command not found for cut, 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 looking, throw away the leftover-box practice file:

rm ~/fruit.csv

Careful delete only. That is delete a leftover-box file carefully.

What this is not

This is not leftover-box search. That is find a word in a leftover-box file. It is not leftover-box order. That is put leftover-box lines in order. It is not leftover-box copies dropped. That is drop leftover-box duplicate lines. It is not handing leftover-box print to another leftover-box tool without leftover-box columns pulled. That is send leftover-box output into another command. It is not leftover-box first leftover-box lines. That is see the start of a leftover-box file. It is not leftover-box last leftover-box lines. That is see the end of a leftover-box file. It is not leftover-box whole dump. That is read a leftover-box file without opening the editor. It is not leftover-box words you typed. That is put a short line into a leftover-box file. It is not watching leftover-box print while you save a leftover-box copy. That is watch and save leftover-box output at once. It is not a quiet leftover-box save. That is save leftover-box output to a file. It is not a house share other computers browse. That is a folder the house can open.

What next

Need leftover-box columns joined side by side after leftover-box columns pulled? Join leftover-box columns side by side. Need leftover-box characters cleaned next? Change leftover-box characters. Need leftover-box copies dropped first? Drop leftover-box duplicate lines. Need leftover-box lines in A-to-Z order? Put leftover-box lines in order. Need leftover-box print handed to another leftover-box tool? Send leftover-box output into another command. Need leftover-box print on screen and in a leftover-box file? Watch and save leftover-box output at once. Need a quiet leftover-box save with no leftover-box print in the window? Save leftover-box output to a file. Need leftover-box words you typed? Put a short line into a leftover-box file. Need a short dump of the leftover-box file you just made? Read a leftover-box file without opening the editor. Need only matching leftover-box lines first? Find a word in a leftover-box file. Need leftover-box first leftover-box lines, not leftover-box columns? See the start of a leftover-box file. Need leftover-box last leftover-box lines? See the end of a leftover-box file. 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 leftover-box cut over leftover-box files you care about, leftover-box paths under /etc, and leftover-box SSH settings. Practice only leftover-box files you just made in home.
• Skip leftover-box awk, leftover-box xargs, leftover-box sort -u, leftover-box sort then leftover-box uniq then leftover-box cut, and leftover-box huge leftover-box logs on leftover-box night one. leftover-box cut by itself is enough for leftover-box first leftover-box look.
• Skip leftover-box cut on leftover-box ls -lh leftover-box spaces. leftover-box ls -lh pads leftover-box spaces, and leftover-box cut -d' ' does not land leftover-box columns where leftover-box eyes expect. Skip leftover-box cut piped into leftover-box rm. Practice leftover-box tools that print, then leftover-box peek with leftover-box 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 pull leftover-box columns from a coffee shop. That is keep the leftover box on the house network.
