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
This package is an ES module and must be loaded using
