suspend

Suspend the execution of the current shell. More information: https://www.gnu.org/software/bash/manual/bash.html#index-suspend.

• Suspend the current shell (useful for when you are in nested shells like su):

bash <Enter> suspend

• Run in a separate terminal to continue from suspension if suspend was used in a non-nested shell:

pkill -CONT bash

• Force suspension even if this would lock you out of the system:

suspend -f
