Try looking at "evtest".

Thanks Mr. Marjal, for replying to my query.

First of all, my apology for typing incorrectly the word Peripheral.

My dear illustrious leaders and senior list members of debian-user,

Checked a few of stackoverflow questions with your input and the
string [stackoverflow "monitor mouse" debian].

These are about monitoring mouse/keystroke
programmatically using c programming language, not with bash script.
BUT my point is that GNU/Linux system must be doing this. I like to
seek the data from the system program(s) that is/are monitoring all
peripherals.

>From these questions, found evemu, but this isn't available in Debian.
Only on freedesktop. But an alternative is available: evemu-tools. But
Debian manpages doesn't have an evemu-tools entry.

Raed the manual of evtest. There are very little
example code lines. evtest isn't installed in the Official Debian
GNU/Linux Live 11.6.0 lxde 2022-12-17T11:46.

Tthe package information was raed for evtest. evtest according to
Debian is only being maintained. Advised that it was better to look for
evemu.

>From the package repository, it was found that evemu have separate
manpages, each for:
evemu-describe
evemu-device
evemu-event
evemu-play
evemu-record

I read the man pages and tried:
evemu-describe /dev/input/eventX
For my laptop.

Could I please be advised on how to:
(1)  monitor event0 (keyboard), event6 (external USB optical mouse) real time?

(2)  If there is a way to monitor mouse-clicks or keystroke, i.e., the
two events, in real time, without a script or a programming language
like c or python?

(3)  monitor the USB ports when some device is inserted into the ports?

Best wishes,
Rajib
