tmbr

Kill processes and process trees.

Simple use cases:

const tmbr = require('tmbr');

// Kill PID 1337 (using SIGTERM) and all of its children
tmbr(1337)

// Use SIGKILL instead
tmbr(1337, 'SIGKILL')

// Try to kill a stubborn process 3 times with SIGTERM,
// then if the process is still alive, send a SIGKILL
tmbr(
  1337, 'SIGTERM', {retries:2}
).catch(
  () => tmbr(1337, 'SIGKILL')
)

asyncKill

Asynchronous kill.

Silently resolves if ESRCH is returned from process.kill(pid, signal).

• signal string Kill signal. (optional, default 'SIGTERM')

• options Object Additional options. (optional, default {})

  • options.recursive boolean Recursive kill.

• Throws any If pid is invalid.

Returns Promise<Object> Resolves if PID kill did not error, rejects otherwise.

killAndCheck

Kill process and check for PID afterwards.

Parameters

• pid number PID.

• signal string Kill signal. (optional, default 'SIGTERM')

• options Object Additional options. (optional, default {})

  • options.recursive boolean Recursive kill.

• Throws any If pid is invalid.

Returns Promise<Object> Resolves if PID kill was successful, rejects otherwise.

lagKill

Wait lag milliseconds, then run killAndCheck.

Parameters

• pid number PID.

• signal string Kill signal. (optional, default 'SIGTERM')

• options Object Additional options. (optional, default {})

  • options.recursive boolean Recursive kill.

• lag (optional, default 0)

• Throws any If pid is invalid.

Returns Promise Resolves if PID kill was successful, rejects otherwise.

processExists

Process with PID exists.

Parameters

• pid number PID.

Returns boolean True if the PID exists, false otherwise.
