Parse::Netstat - Parse the output of "netstat" command


This document describes version 0.150 of Parse::Netstat (from Perl distribution Parse-Netstat), released on 2022-12-04.


 use Parse::Netstat qw(parse_netstat);
 my $res = parse_netstat(output => join("", `netstat -anp`), flavor=>'linux');




 parse_netstat(%args) -> [$status_code, $reason, $payload, \%result_meta]

Parse the output of "netstat" command.

This utility support several flavors of netstat. The default flavor is linux. Use --flavor to select which flavor you want.

Since different flavors provide different fields and same-named fields might contain data in different format, and also not all kinds of possible output from a single flavor are supported, please see the sample parse output for each flavor (in corresponding Parse::Netstat::* per-flavor module) you want to use and adjust accordingly.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • flavor => str (default: "linux")

    Flavor of netstat.

  • output* => str

    Output of netstat command.

    This utility only parses program's output. You need to invoke "netstat" on your own.

  • tcp => bool (default: 1)

    Parse TCP connections.

  • udp => bool (default: 1)

    Parse UDP connections.

  • unix => bool (default: 1)

    Parse Unix socket connections.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
