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 descriptions
• default actions, including whether they can be prevented
• whether the signal is supported by the current OS

Example

import { signalsByName, signalsByNumber } from 'human-signals'

console.log(signalsByName.SIGINT)
// {
//   name: 'SIGINT',
//   number: 2,
//   description: 'User interruption with CTRL-C',
//   supported: true,
//   action: 'terminate',
//   forced: false,
//   standard: 'ansi'
// }

console.log(signalsByNumber[8])
// {
//   name: 'SIGFPE',
//   number: 8,
//   description: 'Floating point arithmetic error',
//   supported: true,
//   action: 'core',
//   forced: false,
//   standard: 'ansi'
// }

Install

npm install human-signals
