Use the sleep command.
sleep
Example:
sleep .5 # Waits 0.5 second.sleep 5 # Waits 5 seconds.sleep 5s # Waits 5 seconds.sleep 5m # Waits 5 minutes.sleep 5h # Waits 5 hours.sleep 5d # Waits 5 days.
One can also employ decimals when specifying a time unit; e.g. sleep 1.5s
sleep 1.5s
And what about:
read -p "Press enter to continue"
In Python (question was originally tagged Python) you need to import the time module
import timetime.sleep(1)
or
from time import sleepsleep(1)
For shell script is is just
sleep 1
Which executes the sleep command. eg. /bin/sleep
/bin/sleep
