Hi Ethen,
below is an example of how you can parse the information on your file.
Note that you can use your file descriptor (INFD) where I have <DATA> to read the info from the file.
To execute svrmngr use the system function instead of the final print.

use strict;
use warnings;

my @data = <DATA>;
my %conf = ();
map{ $_ =~ /(\w*)\s*=[^\w]*(.*)('|")/; $conf{$1} = $2; } grep /=/, @da
+ta;

#use Data::Dumper;
#print Dumper(\%conf); # to see what we got

print ("srvmngr -g $conf{'GATEWAY'} -s $conf{'USER'} -.....");

__DATA__
#para.txt
#this file contains the paramters to be used in the #command line.

SRVMNGR  = "E:\siebel\siebsrvr\bin\srvrmgr "

GATEWAY = "gateway server name"
ENTERPRISE SERVER  = "enterprise server name"
SERVER = "server name"
USER  = "user"
PASSWORD = "password"
SYSTEM_NAME = "WfProcMgr"

This outputs

srvmngr -g gateway server name -s user -.....

If you must have the ' or " for the values on the right side, then change the regexp to

map{ $_ =~ /(\w*)\s*=\s*(.*)\n/; $conf{$1} = $2; } grep /=/, @data;
