Forgot to use & after command, need to send process to background

Question

I have been running a program using nohup but I forgot to add & after the command so the terminal is stuck on the process that has been running for hours. the script I am running in python generates 5 processes each time.

Is there anyway I can make the entire script to continue in the background (get the same effect as an &) without killing and rerunning the process.

Answer 1

Hit Ctrl-Z to suspend the process.

Then bg to tell it to run again as a background process.
