interpolation is interpolation, in shell, in awk, in perl -- that is right, you've got three four levels of interpolation in there (quite nuts by my standards) 

use strict; use warnings;
use Data::Dump;
my $line= qq{awk -v start="$(date -d '10 mins ago' +'%b  %e %T')" -v e
+nd="$(date +'%b  %e %T')" '{tm=$1" "$2" "$3}; star
t<tm&&tm<end' /d/d1/logs/stdout-1132.txt};
dd $line;
__END__
Use of uninitialized value $1 in concatenation (.) or string at - line
+ 3.
Use of uninitialized value $2 in concatenation (.) or string at - line
+ 3.
Use of uninitialized value $3 in concatenation (.) or string at - line
+ 3.
"awk -v start=\"0date -d '10 mins ago' +'%b  %e %T')\" -v end=\"0date 
++'%b  %e %T')\" '{tm=\" \"\" \"}; start<tm&&tm<end' /d/d1/logs/stdout
+-1132.txt"

So, not being interested in debugging your shell or awk , I thought I'd just point out the perl errors

Read perlintro and employ some single quotes
