NAME
App::ProcUtils - Command line utilities related to processes
VERSION
This document describes version 0.039 of App::ProcUtils (from Perl
distribution App-ProcUtils), released on 2024-11-15.
SYNOPSIS
This distribution provides the following command-line utilities:
* proc-exists
* proc-kill
* proc-list
* proc-list-parents
* proc-table
FUNCTIONS
exists
Usage:
exists(%args) -> [$status_code, $reason, $payload, \%result_meta]
Check if processes that match criteria exists.
This function is not exported.
Arguments ('*' denotes required arguments):
* cmdline_match => *re*
(No description)
* cmdline_not_match => *re*
(No description)
* code => *code*
Code is given Proc::ProcessTable::Process object, which is a hashref
containing items like "pid", "uid", etc. It should return true to
mean that a process matches.
* exec_match => *re*
(No description)
* exec_not_match => *re*
(No description)
* logic => *str* (default: "AND")
(No description)
* pids => *array[unix::pid]*
(No description)
* quiet => *true*
(No description)
* uids => *array[unix::uid::exists]*
(No description)
Returns an enveloped result (an array).
First element ($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 ($status_code is not 2xx). Fourth element (%result_meta) is
called result metadata and is optional, a hash that contains extra
information, much like how HTTP response headers provide additional
metadata.
Return value: (any)
kill
Usage:
kill(%args) -> [$status_code, $reason, $payload, \%result_meta]
Kill processes that match criteria.
This function is not exported.
This function supports dry-run operation.
Arguments ('*' denotes required arguments):
* cmdline_match => *re*
(No description)
* cmdline_not_match => *re*
(No description)
* code => *code*
Code is given Proc::ProcessTable::Process object, which is a hashref
containing items like "pid", "uid", etc. It should return true to
mean that a process matches.
* exec_match => *re*
(No description)
* exec_not_match => *re*
(No description)
* logic => *str* (default: "AND")
(No description)
* pids => *array[unix::pid]*
(No description)
* signal => *unix::signal* (default: "TERM")
(No description)
* uids => *array[unix::uid::exists]*
(No description)
Special arguments:
* -dry_run => *bool*
Pass -dry_run=>1 to enable simulation mode.

CONTRIBUTING
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.
