andrewysk · 01-24-2021, 05:00 PM

I need to do some reading of long lines with tabs as such from $ss output.

Why would you want to??. Wrapping is on by default and AFAIK there is no way to scroll left to right with the terminal window.. Turning off line wrapping would mean you could never be able to see what extended beyond the edge of the screen.

All you need in reality is to understand that it is one continuous line of text until you see the line break.

One possibility to simplify reading the output would be to send that output to a text file, then open the text file with a word processor such as libre office which would also by default wrap the lines to fit your page format. You could then set it to display the control characters and make it easier to identify the line breaks.

Oh! There is no way to left right scroll in terminal ? I thought there is.
The reason why i can't read the text from terminal is because there is "tab" in the result. when tabs are in it, it all mess up.
Can't output it to a text file, because i want to view it live..

Any other way round ?

You could use sed to change tabs to a character of your choice.

You could change the the font size to something smaller and extend your terminal to have more characters per line.

Or tabs to set the width of the tab-stops.

Or Ctrl+- (minus on the main keyboard) to reduce the font size, then Ctrl+0 (zero) to restore it.

Or, instead of all these crappy workarounds, you could actually just disable line wrapping, by piping to "less -S" and using cursor keys to navigate.

Example:

Code:

ss -p | less -S

WoW!!! Wonderful!!
Now i know less -S has got this feature.. lol!
Thanks. Good stuff that you shared.

I tried to reduce the font size before this, i have to reduce the font till i barely able to read it. lol..that's why i need this |less -S feature.

One more thing,
when I use

Code:

watch

with

Code:

|less -S

; (so that i can watch it real time) it messed up the whole thing.. I don't see any output anymore.

Code:

$ sudo watch ss -tulpn | less -S

Any way to solve this issue ?

I don't think watch can work with less.

Is there a way round to it ?

How do you monitor the traffics in and out of your pc when you think it is abnormally busy ? How and what software used ? what method ?
Thx

Also, I don't think watch can work with more.

watch is a full-screen ncurses application. You cannot combine it with another ncurses application (less, more, whatever).

You can somewhat trim the ss output and make it look slightly more compact.

E.g. with miller:

Code:

sudo watch 'ss -HOtulpn|mlr --n2p --repifs label Id,State,R,S,LA,PA'

Or with tabulate from the Perl module Text::Tabulate

Code:

sudo watch 'ss -HOtulpn|tabulate -t" +"'

Or with the Python script of the same name (slightly less efficient):

Code:

sudo watch 'ss -HOtulpn|tabulate -fplain'

You could even format it with printf as you wish, although this would probably require some testing and adjustment:

Code:

printf '%s %s %d %3d %-17s %9s %.32s\n' $(sudo ss -HOtulpn)

Wow!
You are so knowledgable in these kind of stuff... lol
I am still reading the first row of miller $mlr .. it is tabular tool for csv.. just like sed awk..
the rest have not read yet, no idea what they are, just know they are related to data manipulation..
I have never use it before.

I have give all of your method a try, but all not working.
(method1

I also installed the only tabulate in repo

Code:

 $ sudo pacman -S python-tabulate

Code:

$ sudo watch 'ss -pn | tabulate -fplain'

The result is not different than

Code:

$ sudo watch ss -pn

(method2

As for the command with miller $mlr, error installing miller (both via pamac-manager and yay):

Code:

:: Proceed with installation? [Y/n] 
:: Retrieving packages...
error: failed retrieving file 'ctags-1:r20200106+ga3c87ab5-1-x86_64.pkg.tar.zst' from mirror.23media.com : The requested URL returned error: 404

Hence miller method is not working.

(method3

Method tabulate:

Code:

sudo watch 'ss -HOtulpn|tabulate -t" +"'

not working. no idea where's the problem.

(method4)
method printf:

Code:

printf '%s %s %d %3d %-17s %9s %.32s\n' $(sudo ss -pn)

this is not in realtime and does nothing to make the result more presentable.

Code:

$ printf '%s %s %d %3d %-17s %9s %.32s\n' $(sudo ss -p)

No idea what went wrong. It just does not work on my computer
