How to replace a date inside a text file daily with current date?

Hello All,

we what we call a parameter file (.txt) where my application read dynamic values when the job is triggered, one of such values are below:

abc.txt
------------------
Code:
line1
line2
line3
$$EDWS_DATE_INSERT=08-27-2019
line4
$$EDWS_PREV_DATE_INSERT=08-26-2019

I am trying to write a small command that can update these dates daily with current date but its not replacing the date value.
Code:
sed -i 's/$$EDWS_DATE_INSERT =.*/$$EDWS_DATE_INSERT="$(date `+%y%m%d`)"/' abc.txt

current result: $$EDWS_DATE_INSERT="$(date `+%y%m%d`)"

can anyone help with this ?

Thanks in Advance!

CGI::Untaint::date(3pm) 				User Contributed Perl Documentation				   CGI::Untaint::date(3pm)

NAME
CGI::Untaint::date - validate a date SYNOPSIS
use CGI::Untaint; my $handler = CGI::Untaint->new($q->Vars); my $date = $handler->extract(-as_date => 'date'); DESCRIPTION
is_valid This Input Handler verifies that it is dealing with a reasonable date. Reasonably means anything that Date::Manip thinks is sensible, so you could use any of (for example): "December 12, 2001" "12th December, 2001" "2001-12-12" "next Tuesday" "third Wednesday in March" See Date::Manip for much more information on what date formats are acceptable. The resulting date will be a Date::Simple object. Date::Simple for more information on this. date_format By default ambiguous dates of the format 08/09/2001 will be treated as UK style (i.e. 8th September rather than 9th August) If you want to change this, subclass it and override date_format() WARNING
Date::Manip does not play nicely with taint mode. In order to work around this we locally clobber Date::Manip's 'timezone' code. As we're only interested in dates rather than times, this shouldn't be much of an issue. If it is, then please let me know! SEE ALSO
