I want it to write this info to the file, not to create a new one.
This doesn't happen. A new file is ALWAYS written and the old file replaced. This is simply the method used by operating systems for "text" files of any sort.
The second problem is that you want to check "if it doesn't exist" and then place it there. Well, you can't really do that in one pass. The best solution is to Put it there and remove any existing ones.
So:
If you want to use the integer value found in this proxy section, you're kind of screwed -- you have to either do backtracking or two passes or create a metastructure of all the data and write it out again to XML. That's because you want the ExcludeSimpleHostnames key to follow the array in the output, but the input, it might occur later.

Hello-
I am trying to view a file which is quite large. However, whenever I do 'cat (file name)' it shows me just the half.. I am using Putty to access my server.
Also, is it possible to edit a file from a unix system on a 'Gedit for Windows" text editor?
Thanks (7 Replies)

poe::pipe::oneway
POE::Pipe::OneWay(3pm) User Contributed Perl Documentation POE::Pipe::OneWay(3pm)NAME
POE::Pipe::OneWay - a portable API for one-way pipes
SYNOPSIS
my ($read, $write) = POE::Pipe::OneWay->new();
die "couldn't create a pipe: $!" unless defined $read;
DESCRIPTION
The right way to create an anonymous pipe varies from one operating system to the next. Some operating systems support "pipe()". Others
require "socketpair()". And a few operating systems support neither, so a plain old socket must be created.
POE::Pipe::OneWay will attempt to create a unidirectional pipe using "pipe()", "socketpair()", and IO::Socket::INET, in that order.
Exceptions are hardcoded for operating systems with broken or nonstandard behaviors.
The upshot of all this is that an application can portably create a one-way pipe by instantiating POE::Pipe::OneWay. The work of deciding
how to create the pipe and opening the handles will be taken care of internally.
POE::Pipe::OneWay may be used outside of POE, as it doesn't use POE internally.
PUBLIC METHODS
new [TYPE]
Create a new one-way pipe, optionally constraining it to a particular TYPE of pipe. One-way pipes have two ends: a "read" end and a
"write" end. On success, new() returns two handles: one for the "read" end and one for the "write" end. Returns nothing on failure, and
sets $! to explain why the constructor failed.
my ($read, $write) = POE::Pipe::OneWay->new();
die $! unless defined $read;
TYPE may be one of "pipe", "socketpair", or "inet". When set, POE::Pipe::OneWay will constrain its search to either "pipe()", a UNIX-
domain "socketpair()", or plain old sockets, respectively. Otherwise new() will try each method in order, or a particular method
predetermined to be the best one for the current operating environment.
BUGS
POE::Pipe::OneWay may block up to one second on some systems if failure occurs while trying to create "inet" sockets.
