2.测试程序内容

#!/usr/bin/perl

use strict;

our($host, $dbname, $user, $password);

my $prog_root="/usr/test_prog";

my $prog_conf = $prog_root."/test.conf";

open my $conf_file,"<",$prog_conf;

my @conf_items = <$conf_file>;

close($conf_file);

foreach my $line(@conf_items){

   #### read each line from configration file

   $host = $1 if ($line =~/host\s*=\s*(\S+)\s*;/i);

   $dbname=$1 if ($line =~/dbname\s*=\s*(\S+)\s*;/i);

   $user=$1 if ($line =~/user\s*=\s*(\S+)\s*;/i);

   $password=$1 if ($line =~/pwd\s*=\s*(\S+)\s*;/i);

}

print "$host\n";

print "$dbname\n";
