I don't recommend using the quotemeta operator. That will usually misquote newlines with POSIX-like shells.
Instead, skip the shell and use the multiple argument form pipe open, such as
my $output;
{
my @command = "sudo", "/usr/bin/python", "/home/processLog.py", $n
+ame, $age, $text, $id;
open my $P, "-|", @command or
die "error pipe opening program";
local $/;
$output = <$P>;
close $P or
die "error: spawned program exited with failure or cannot read
+ pipe";
# note: you may want to accept an exit failure with some programs.
+ if you do, check eof($P) instead to catch a read error.
}
print $output;
Update: added "skip the shell".

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
