The Silicon Guide To
Using Server Side Includes

The Echo Command

The echo command is used to display information about the current state of affairs on your server. 

The syntax to use any echo command is:
<!--#echo var="COMMANDGOESHERE"-->

For example to display the current date I would insert the followind into my HTML code:
<!--#echo var="DATE_LOCAL"-->,
since DATE_LOCAL is the command used to display the current local date.  The result is:
Friday, 12-Dec-2025 19:03:37 EST

Here is a list of all the echo commands at your disposal, along with a description of what they do, and a real-time example:
