NAME Proc::Find::Parents - Find parents of a process (up to the root) VERSION This document describes version 0.631 of Proc::Find::Parents (from Perl distribution Proc-Find-Parents), released on 2018-01-17. SYNOPSIS FUNCTIONS None are exported by default, but they are exportable. get_parent_processes($pid[, \%opts]) => ARRAY Return an array containing information about parent processes of $pid up to the parent of all processes (usually "init"). If $pid is not mentioned, it defaults to $$. The immediate parent is in the first element of array, followed by its parent, and so on. For example: [{name=>"perl",pid=>13134}, {name=>"konsole",pid=>2232}, {name=>"init",pid=>1}] Currently retrieves information by calling pstree program. Return undef on failure. Known options: * method => STR (default: "proctable") Either "proctable" (the default, which means to use Proc::ProcessTable) or "pstree" (which uses the pstree command, which might not be portable between Unices). HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at . BUGS Please report any bugs or feature requests on the bugtracker website When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature. SEE ALSO Proc::ProcessTable. Pros: does not depend on "pstree" command, process names not truncated by "pstree", works on Windows. Cons: a little bit more heavyweight (uses File::Spec, Cwd, File::Find). AUTHOR perlancar COPYRIGHT AND LICENSE This software is copyright (c) 2018, 2014, 2013 by perlancar@cpan.org.
