pause-firefox - Pause (kill -STOP) Firefox
This document describes version 0.015 of pause-firefox (from Perl distribution App-FirefoxUtils), released on 2020-08-18.
% pause-firefox [--debug] [--format=name] [--json] [--log-level=level] [--(no)naked-res] [--page-result[=program]] [--quiet] [--trace] [--user=s+] [--users-json=s] [--verbose]
A modern browser now runs complex web pages and applications. Despite browser's power management feature, these pages/tabs on the browser often still eat considerable CPU cycles even though they only run in the background. Stopping (kill -STOP) the browser processes is a simple and effective way to stop CPU eating on Unix. It can be performed whenever you are not using your browser for a little while, e.g. when you are typing on an editor or watching a movie. When you want to use your browser again, simply unpause it.
* marks required options.

Choose output format, e.g. json, text.
Set output format to json.
When outputing as JSON, strip result envelope.
By default, when outputing as JSON, the full enveloped result is returned, e.g.:
The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use `--naked-res` so you just get:
Filter output through a pager.
This script has shell tab completion capability with support for several shells.
To activate bash completion for this script, put:
complete -C pause-firefox pause-firefox
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.
To activate tcsh completion for this script, put:
complete pause-firefox 'p/*/`pause-firefox`/'
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).
For fish and zsh, install shcompgen as described above.
