CPU usage limiter for Linux, driven by user's shift of attention

bash-checkIT

This repos contains building blocks to track and act upon user's shift of attention; specifically to deny standby power to greedy applications - like chrome and firefox - while retaining as much functionnality as possible.

How to install

• sudo apt install xdotool
• backup ~/.bashrc
• add content of .bashrc.addon to ~/.bashrc
• copy file .bashrc.checkIT.lib.v1 to ~/
• run source ~/.bashrc

How to use

run checkFirefox, toggle Firefox window.

Examples

Chrome to pause on blur event and to resume on focus event:

checkProcess 'chrome' 'chrome'

Firefox to pause 5 seconds past onblur event unless current tab title matches fond or favorite:

checkProcess 'Firefox' 'firefox' 'unless' '(fond|favorite)' 'with pause surge delays of' 5 0

Slack to pause 5 seconds past onblur event and to awaken for 5 seconds every 30 seconds:

checkProcess 'Slack' 'slack' 'with pause surge delays of' 5 30

Detailed usage

checkProcess classMatcher pidofNameArg ['unless' titleMatcher] ['with pause surge delays of' pauseDelay surgeDelay]
