So I am using node.js' built-in debugger and trying to skip the "break on first line" that it performs by passing in a delayed "c" keypress (c=continue) using echo, as such:

(sleep 1; echo -ne 'c\n') | node debug ~/src/main.js

It works as expected, but the node debugger no longer seems to accept keyboard input afterwords. I assume the piping in bash is doing something to cause node to ignore the keyboard. Anyone know how I can achieve the same result but maintain keyboard input to the node program?

Because node is being run in a pipeline, its input file descriptor is open to the pipeline, not to the console.

A common way to feed input to a process and then allow the user to interact is to use expect or pexpect.
