I have a situation were I run a certain command which prints to STDOUT. I capture this STDOUT in a buffer. The problem is that if the string captured in the buffer contains any symbols special to Perl, they are getting expanded, which I don't want to happen. I want to capture the string in the buffer in a literal mode. Is there some kind of syntax I can use to achieve this? If you suggest using single quotes to me, please demonstrate how, as I cannot see how it could possible fit in the sample code. Lastly I have my reasons for not wanting to use taint mode.

use strict;

sub runCLIcommand
{
    local *STDERR;

    my $lineSTDERR;
    my $returnValue = 0;

    open STDERR, '>', \$lineSTDERR;

    # This simulates what would in reality come from a command line in
+terface. 
    # In reality I would invoke: commands::display::ssh::run();
    # which in turn would print to STDOUT. 
    print "%dsadada ssadasd\n"; # Hash symbol does not cause a problem
+, which I think is inconsistent?
    print "@dsadada sdsadasd\n"; # Problem !!!!!!!!!!!!!!!!!!!!!!!!!!!
+!!!!!!!!!!
    print "$dsadada sdsadasd\n"; # Problem !!!!!!!!!!!!!!!!!!!!!!!!!!!
+!!!!!!!!!!
    # Looks for these declarations: my @dsadada; my $dsadada;

    # Check that there was nothing written to STDERR, which implies
    # everything went alright.
    if (length($lineSTDERR) > 0) {
        $returnValue = 1;
    }

    return $returnValue;
}

sub processCLIoutput
{
    my $array_ref = $_[0];

    my @array = @$array_ref;

    for (my $i = 0; $i < @array; $i++) {
        $array[$i] =~ s/^\s*//;
        $array[$i] =~ s/\s*$//;

        # Not a neat solution plus, doesn't work in the simulation, 
        # since the print command itself gets there first. 
        $array[$i] =~ s/\$/DOLLAR/g;
        $array[$i] =~ s/\@/ARRAY/g;
        $array[$i] =~ s/\%/HASH/g;
    }

    return \@array;
}

sub getSshDetails
{
    local *STDOUT;

    my @sshDetails = ();
    my @capturedSTDOUT;
    my $lineSTDOUT;
    my $array_ref;

    open STDOUT, '>', \$lineSTDOUT || die "Could not open STDOUT. $!";

    # Anything that is printed to STDOUT from now on is captured in th
+e buffer
    # $linesSTDOUT. Is there some kind of syntax I can use here that d
+isables 
    # variable expansion of the captured output???????????????????????
+????????????????????? 

    if (runCLIcommand() != 0) {
        die "CLI command did not run successfully. \n";
    }

    @capturedSTDOUT = split(/\n/, ($lineSTDOUT));
    $array_ref = processCLIoutput(\@capturedSTDOUT);
    @sshDetails = @$array_ref;

    return \@sshDetails;
}

# main:

my $array_ref = getSshDetails();
my @array = @$array_ref;

for (my $i = 0; $i < @array; $i++) {
    print "Array entry: ". $i. "\t". $array[$i]. "\n";
}

PS: The above will not work unless you remove the '@' and '$' from the print statements. For some reason this is not a problem for the % symbol which, I find inconsistent. Surely the same attempt at variable expansion would apply to all the primitives.
