Description

I run the following code:
ssh.exec(
'sudo -S dd if=/mnt/storage/disks/other6 of=/mnt/storage/disks/other7',
['status=progress'],
{
execOptions: { pty: true },
stdin: '1234',
onStdout(chunk) {
console.log('stdoutChunk', chunk.toString());
},
onStderr(chunk) {
console.log('stderrChunk', chunk.toString());
},
},
);
And everything hangs on this output:
hello
stdoutChunk 1234
stdoutChunk Password:

Research direction

Start with the supplied ssh.exec call and reproduce the sudo -S dd command using the shown PTY and stdin options. Trace how the library handles stdin and the sudo password prompt, including the stdout and stderr callbacks. Done means the command no longer hangs and its output is observable through the documented callbacks.
