import { KillSignalController } from "https://deno.land/x/dax@0.39.2/src/command.ts";
Send a signal to the downstream child process. Note that SIGTERM, SIGKILL, SIGABRT, SIGQUIT, SIGINT, or SIGSTOP will cause all the commands to be considered "aborted" and will return a 124 exit code, while other signals will just be forwarded to the commands.
Parameters
optional
signal: Deno.Signal = [UNSUPPORTED]
