Shell Scripting: Delayed Execution of Echo Statements

Question

Is there any way to run multiple echo statements one after the other with a delay?

For example:

The first statement would be:

echo Hello1

after 1/2 second, run the second echo expression:

echo Hello2

Likewise, is it possible to run multiple statements one after the other with a time delay without printing all the echoes at once?

Perhaps you would like to use sleep <number of seconds>

For example sleep 60

to wait a minute.

eg. run from command line

$echo 'hello1'; sleep 2; echo 'hello2'

or in a bash script file (myscript.sh)

#!/bin/bash
echo 'hello1'
sleep 2
echo 'hello2 after 2 seconds'
sleep 2
echo 'hello3 after 2 seconds'
