API

spawnWriteStream(command)

spawnWriteStream(command, opts)

spawnWriteStream(command, args)

spawnWriteStream(command, args, opts)

Returns a writable stream. Uses child_process.spawn to spawn the process. If the process fails, an error is emitted on the stream.

For clarity, command is allowed to be an array, for cases like zfs send, where zfs clearly isn't a very useful description of what command is being run. This only makes a difference for error reporting.

The child process exit event is re-emitted on the stream, after any error events.

ExitError

• name: ExitError
• stderr: stderr output of the process (Buffer)

then, depending on how it exited:

• signal: signal that killed the process (string)
• message: '`' + command + '` killed by signal `' + err.signal + '`'

or

• code: exit code (integer)
• message: '`' command + '` exited with ' + err.code
