How do I get the pid of a spawned process using pexpect?

Question

I am using pexpect to spawn a bash shell and then using sendline to execute other processes within the bash shell.

Is there any way to get the pid of the spawned bash shell?
How can I get the pid of the process that I have started within bash?

Answer 1

If you check the documentation of the spawn class you'll find that you can get the pid of the spawned process with the pid attribute, so

spawnedBash = pexpect.spawn('bash')
print(spawnedBash.pid)

should print your spawned process's pid
