## README
> Fabulously kill processes. Cross-platform.

## Install

npm install fkill
```
## Usage
```js
import fkill from 'fkill';

fkill('Safari');

fkill([1337, 'Safari', ':8080']);

## API
### fkill(input, options?)
Returns a promise that resolves when the processes are killed.
#### input
Type: `number | string | Array`
One or more process IDs/names/ports to kill.
To kill a port, prefix it with a colon. For example: `:8080`.
On Windows, process extensions are optional. For example, both `fkill('notepad')` and `fkill('notepad.exe')` work.
#### options
Type: `object`
##### force
Type: `boolean`\
Default: `false`
Force kill the processes.
##### forceAfterTimeout
Type: `number`\
Default: `undefined`
Force kill processes that did not exit within the given number of milliseconds.
##### tree
Type: `boolean`\
Default: `true`
Kill all child processes along with the parent process. *(Windows only)*
##### ignoreCase
Type: `boolean`\
Default: `false`
Ignore capitalization when killing a process.
Note that the case is always ignored on Windows.
##### silent
Type: `boolean`\
Default: `false`
Suppress all error messages. For example: `Process doesn't exist`.
##### waitForExit
Type: `number`\
Default: `undefined`
Wait for processes to exit before returning.
Specifies the maximum time to wait in milliseconds. If processes haven't exited by then, an error is thrown (unless `silent: true`).
```js
// Wait up to 2 seconds for Chrome to exit
await fkill('chrome', {waitForExit: 2000});
// Wait up to 5 seconds for database to shutdown gracefully
await fkill(dbPid, {waitForExit: 5000});
```
