How do I pause my shell script for a second before continuing?
Popular Answer
Use the sleep command.
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

In Python (question was originally tagged Python) you need to import the time module
import time
time.sleep(1)
or
from time import sleep
sleep(1)
For shell script is is just
sleep 1
Which executes the sleep command. eg. /bin/sleep

I realize that I'm a bit late with this, but you can also call sleep and pass the disired time in. For example, If I wanted to wait for 3 seconds I can do:
/bin/sleep 3
4 seconds would look like this:
/bin/sleep 4

On Mac OSX, sleep does not take minutes/etc, only seconds. So for two minutes,
sleep 120

Run multiple sleeps and commands
sleep 5 && cd /var/www/html && git pull && sleep 3 && cd ..
This will wait for 5 seconds before executing the first script, then will sleep again for 3 seconds before it changes directory again.
