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, $payload, \%result_meta] Kill processes that match criteria. This function is not exported. This function supports dry-run operation. Arguments ('*' denotes required arguments): * cmdline_match => *re* (No description) * cmdline_not_match => *re* (No description) * code => *code* Code is given Proc::ProcessTable::Process object, which is a hashref containing items like "pid", "uid", etc. It should return true to mean that a process matches. * exec_match => *re* (No description) * exec_not_match => *re* (No description) * logic => *str* (default: "AND") (No description) * pids => *array[unix::pid]* (No description) * signal => *unix::signal* (default: "TERM") (No description) * uids => *array[unix::uid::exists]* (No description) Special arguments: * -dry_run => *bool* Pass -dry_run=>1 to enable simulation mode. Returns an enveloped result (an array). First element ($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 ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) list Usage: list(%args) -> [$status_code, $reason, $payload, \%result_meta] List processes that match criteria. 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. * detail => *true* Return detailed records instead of just PIDs. * exec_match => *re* (No description) * exec_not_match => *re* (No description) * logic => *str* (default: "AND") (No description) * pids => *array[unix::pid]* (No description) * uids => *array[unix::uid::exists]* (No description) Returns an enveloped result (an array).

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) list_parents Usage: list_parents() -> [$status_code, $reason, $payload, \%result_meta] List all the parents of the current process. This function is not exported. No arguments. Returns an enveloped result (an array). First element ($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 ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) table Usage: table() -> [$status_code, $reason, $payload, \%result_meta] Run Proc::ProcessTable and display the result. This function is not exported. No arguments. Returns an enveloped result (an array). First element ($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.

AUTHOR perlancar 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. COPYRIGHT AND LICENSE This software is copyright (c) 2024 by perlancar .
