I have been trying a few filtering scripts with both SED and PERL. So far I have both of these versions working to reformat the incoming text stream (from stdin) into the corrent format (it looks good in the terminal), but I don't think that I am doing it right because the formatted text is not available to other applications/operations... but I can see it coming through in the terminal? Is this weird?
this is my setup:
% foo.app | perlFilter.pl
Works great - I can see it in the terminal, but
% foo.app | perlFilter > text
puts nothing into the file text!
% foo.app | perlFilter | nc 127.0.0.1 5001
Shows nothing going through to
nc -l -p 5001
Running nc in verbose mode shows that nothing is going through...
Here is my PERL script:
Do I need to explicitly write out to stdout or something?
Is there a way to send the syslog output for a given facility to stderr or stdout?
I do not want to use the "tail" command to achieve this, I would like it to go directly to stderr.
Thanks in advance (1 Reply)
Hello everybody,
Is there a more elegant way to make dual output (display on standard output and append to a file) while I'm executing a shell script, besides duplicating the echo command for every string?
echo "Message..." > 1
echo "Message..." >> myfile.out
Thank you for your time,... (2 Replies)
This is about getting all output to stderr and stdout localized. Nothing to do with redirecting output to a file (there already are some interesting threads about that issue on this forum).
What I intend to do is capturing all lines of text sent to the screen, compare them with an array of... (2 Replies)

mojo
Mojo(3pm) User Contributed Perl Documentation Mojo(3pm)NAME
Mojo - Duct tape for the HTML5 web!
SYNOPSIS
use Mojo::Base 'Mojo';
# All the complexities of CGI, PSGI, HTTP and WebSockets get reduced to a
# single method call!
sub handler {
my ($self, $tx) = @_;
# Request
my $method = $tx->req->method;
my $path = $tx->req->url->path;
# Response
$tx->res->code(200);
$tx->res->headers->content_type('text/plain');
$tx->res->body("$method request for $path!");
# Resume transaction
$tx->resume;
}
DESCRIPTION
Mojo provides a flexible runtime environment for Perl real-time web frameworks. It provides all the basic tools and helpers needed to write
simple web applications and higher level web frameworks such as Mojolicious.
See Mojolicious for more!
ATTRIBUTES
Mojo implements the following attributes.
"home"
my $home = $app->home;
$app = $app->home(Mojo::Home->new);
The home directory of your application, defaults to a Mojo::Home object which stringifies to the actual path.
# Generate portable path relative to home directory
my $path = $app->home->rel_file('data/important.txt');
"log"
my $log = $app->log;
$app = $app->log(Mojo::Log->new);
The logging layer of your application, defaults to a Mojo::Log object.
# Log debug message
$app->log->debug('It works!');
"ua"
my $ua = $app->ua;
$app = $app->ua(Mojo::UserAgent->new);
A full featured HTTP 1.1 user agent for use in your applications, defaults to a Mojo::UserAgent object. Note that this user agent should
not be used in plugins, since non-blocking requests that are already in progress will interfere with new blocking ones.
# Perform blocking request
my $body = $app->ua->get('mojolicio.us')->res->body;
METHODS
Mojo inherits all methods from Mojo::Base and implements the following new ones.
"new"
my $app = Mojo->new;
Construct a new Mojo application. Will automatically detect your home directory and set up logging to "log/mojo.log" if there's a "log"
directory.
"build_tx"
my $tx = $app->build_tx;
Transaction builder, defaults to building a Mojo::Transaction::HTTP object.
"config"
my $config = $app->config;
my $foo = $app->config('foo');
$app = $app->config({foo => 'bar'});
$app = $app->config(foo => 'bar');
Application configuration.
# Manipulate configuration
$app->config->{foo} = 'bar';
my $foo = $app->config->{foo};
delete $app->config->{foo};
"handler"
$app->handler($tx);
The handler is the main entry point to your application or framework and will be called for each new transaction, which will usually be a
Mojo::Transaction::HTTP or Mojo::Transaction::WebSocket object. Meant to be overloaded in a subclass.
sub handler {
my ($self, $tx) = @_;
...
}
