Keeping a long-running command going without interruption through kubectl exec through timeouts

kubectl_timeout_evade_trick.sh

# This trick keeps the kubectl session active by printing the current time every 10 seconds
#
# Run commands like this
(while true; do sleep 10; date; done) & <YOUR LONG RUNNING COMMAND GOES HERE>

# For example:
(while true; do sleep 10; date; done) & sha512sum my_super_large_file.dat | tee checksum.sha512

# When done, to get control back, run this command:
fg

# Then press CTRL+C
