I want to read the value of variable from environment file and set it to another properties file using perl script.

Environment File

DOMAIN=<value>
DOMAIN_TEST_DB_CONN_STR=<value>
DOMAIN_TEST_DB_USER=<value>
DOMAIN_TEST_DB_PSWD=<value>

Properties File

#These are the properties for engineering
#We expect you to change them for your environment
#
#CustomerDatabase info
DOMAIN=<value>
DOMAIN_TEST_DB_CONN_STR=<value>
DOMAIN_TEST_DB_USER=<value>
DOMAIN_TEST_DB_PSWD=<value>

I tried following but not working. Kindly please suggest.

$envfile="/root/env.properties"; 
@envFile=<$env>;
open my $env,  '<',  $envfile      or die "Can't read old file: $!";
open my $in,  '<',  $file      or die "Can't read old file: $!";
open my $out, '>', "$file.new" or die "Can't write new file: $!";


print "\nFile contents:";
print @envFile;

foreach $envline (@envFile){

while ( <$in> ){
        print "$. $_";
        if($envline =~/$DOMAIN_DB_CONN_STR=.*:1521:.*/ && $_=~/$DOMAIN
+_DB_CONN_STR=.*:1521:.*/){
                print "\nMatch";
                $line=$_;
                $line =~ s/$DOMAIN_DB_CONN_STR=.*:1521:.*/NUANCE_DB_CO
+NN_STR=$dbhost:$dbport:$dbschema/;
                print $out $line;
        }
}
}
