Put existing running process in background on Linux

In case you need to put existing running process on the current shell in the background for some reason. Please apply following steps:

example:

# echo "Hello World" ; sleep 100
# run ctrl z keyboard keys together
# bg
# disown -h
# exit

Explanation: Ctrl z will pause the program and will bring you back to the shell, bg command will put the process in background and disown -h will make sure that the process is not killed when you exit the terminal. exit is pretty much self explanatory.
