Human-friendly process signals.
This is a map of known process signals with some information about each signal.
Unlike
os.constants.signals
this includes:
- human-friendly description, default action and priority
- signals not supported by the current OS, which means you can safely use this on any platform
Example
const { signalsByName, signalsByNumber } = require('human-signal')
console.log(signalsByName.SIGTERM)
// {
// name: 'SIGINT',
// number: 2,
// description: 'User interruption with CTRL-C',
// action: 'terminate',
// priority: false,
// source: 'ansi'
// }
console.log(signalsByNumber[8])
// {
// name: 'SIGFPE',
// number: 8,
// action: 'core',
// description: 'Floating point arithmetic error',
// priority: false,
// source: 'ansi'
// }Install
npm install human-signalUsage
