Perl - pass shell-vars into perl for input loop

I need to process a file line-by-line using some value from a shell variable

Something like:
Code:
perl -p -e 's/$shell_srch/$shell_replace/g' input.txt

I can't make the '-s' work in the '-p' or '-n' input loop (or couldn't find a syntaxis.)
I have searched and found https://www.unix.com/302343759-post2.html, but it doesn't work

Is it possible (without havy sysntaxis, as ENV(..), for exmpl.) in the input loop?

IO::All::HTTP(3pm)					User Contributed Perl Documentation					IO::All::HTTP(3pm)

NAME
IO::All::LWP - Extends IO::All to HTTP URLs SYNOPSIS
use IO::All; $content < io('http://example.org'); # GET webpage into scalar io('http://example.org') > io('index.html'); # GET to file "hello " > io('http://example.org/index.html'); # PUT webpage # two ways of getting a page with a password: $content < io('http://me:secret@example.org'); $content < io('http://example.org')->user('me')->password('secret'); DESCRIPTION
This module extends IO::All for dealing with HTTP URLs. Note that you don't need to use it explicitly, as it is autoloaded by IO::All whenever it sees something that looks like an HTTP URL. The SYNOPSIS shows some simple typical examples, but there are many other interesting combinations with other IO::All features! For example, you can get an HTTP URL and write the content to a socket, or to an FTP URL, of to a DBM file. METHODS
This is a subclass of IO::All::LWP. The only new method is "http", which can be used to create a blank IO::All::HTTP object; or it can also take an HTTP URL as a parameter. Note that in most cases it is simpler just to call io('http://example.com'), which calls the "http" method automatically. OPERATOR OVERLOADING
The same operators from IO::All may be used. < GETs an HTTP URL; > PUTs to an HTTP URL. SEE ALSO
IO::All, IO::All::LWP, LWP. AUTHORS
