The following example sets a boot script and then shows it running.
RedBoot> fconfig
Run script at boot: false t
Boot script:
Enter script, terminate with empty line
>> fi li
Boot script timeout: 0 10
Use BOOTP for network configuration: false .

NOTE: The bold characters above indicate where something was entered on the console. As you can see,
the fi li command at the end came from the script, not the console. Once the script is executed, command
processing reverts to the console.
NOTE: RedBoot supports the notion of a boot script timeout, i.e. a period of time that RedBoot waits before
executing the boot time script. This period is primarily to allow the possibility of canceling the script. Since a
timeout value of zero (0) seconds would never allow the script to be aborted or canceled, this value is not
allowed. If the timeout value is zero, then RedBoot will abort the script execution immediately.
On many targets, RedBoot may be configured to run from ROM or it may be configured to run from RAM. Other
configurations are also possible. All RedBoot configurations will execute the boot script, but in certain cases it
may be desirable to limit the execution of certain script commands to one RedBoot configuration or the other. This
can be accomplished by prepending
{
<
startup type>}
to the commands which should be executed only by the
RedBoot configured for the specified startup type. The following boot script illustrates this concept by having the
ROM based RedBoot load and run the RAM based RedBoot. The RAM based RedBoot will then list flash images.
