Search through magento admin panel to see which script are loaded where

Question

I am using magento2.3.5-p2 Community Edition

I am having a problem on finding the location of certain code,

I have tried templatehints, search using grep and find all contents in file but to no avail the code still not able to be find

The code below, the highlighted one is the one I am trying to find the location of that

When I inspect element the page, the code is not hovering to any element, the nearest element is the footer but I am unsure, do take a look at image below

When I hover into the

<div class="debugging-hints" that is which is the nearest to the <noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-GE2HRWD" height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript> only then I will get the source file which is at

/var/www/html/myecommerceproject/app/code/MageBig/QuickView/view/frontend/templates/quickview.popup.phtml

but even then. When I check on the source code for the intended script I want to find it does not exists, It must be somewhere in the configuration of Magento admin panel, but I am not sure where

Any help is kindly appreciated, thank you

Answer 1

Simply you can use grep command for search in file through SSH

grep -l -r "your string" foldername/

e.g grep -l -r "www.googletagmanager.com/" vendor/magento

e.g grep -l -r "www.googletagmanager.com/" app/

Answer 2

within magento root folder, do a

grep -R '<!-- GOOGLE TAG MANAGER -->' vendor/magento/module-*

and you can look at all the templates using this code
