I ran in shell:

#! /bin/bash


echo "Today is $log"

echo "Today is 'date'"

but the result is : Today is monday Today is 'date'

How do I make it display the day and date. Thank you for searching。

The reason why you are echoing the literal string date is because you are using single-quotes.

To ensure that you echo the output of date you need to use back-ticks


echo "Today is `date`"

This will output:

Today is Sun Apr  8 11:06:37 BST 2012
