NAME

ppgrep - Look up parents' processes based on name and other attributes

VERSION

This document describes version 0.033 of main (from Perl distribution App-ppgrep), released on 2019-11-29.

SYNOPSIS

Usage:

COMPLETION

The script comes with a companion shell completer script (_ppgrep) for this script.

bash

To activate bash completion for this script, put:

complete -C _ppgrep ppgrep

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.

tcsh

To activate tcsh completion for this script, put:

complete ppgrep 'p/*/`ppgrep`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.
