Configuring Packages and Their Services
Creating the Package Control Script
Chapter 6302
Adding Customer Defined Functions to the Package
Control Script
You can add additional shell commands to the package control script to
be executed whenever the package starts or stops. Simply enter these
commands in the CUSTOMER DEFINED FUNCTIONS area of the script. This
gives you the ability to further customize the control script.
An example of this portion of the script is shown below, with the date
and echo commands included to log starts and halts of the package to a
special file.
# START OF CUSTOMER DEFINED FUNCTIONS
# This function is a place holder for customer defined functions.
# You should define all actions you want to happen here, before the service is
# started. You can create as many functions as you need.
function customer_defined_run_cmds
{
# ADD customer defined run commands.
: # do nothing instruction, because a function must contain some command.
date >> /tmp/pkg1.datelog
echo 'Starting pkg1' >> /tmp/pkg1.datelog
test_return 51
}
# This function is a place holder for customer defined functions.
# You should define all actions you want to happen here, before the service is
# halted.
function customer_defined_halt_cmds
{
# ADD customer defined halt commands.
: # do nothing instruction, because a function must contain some command.
date >> /tmp/pkg1.datelog
echo 'Halting pkg1' >> /tmp/pkg1.datelog
test_return 52
}
# END OF CUSTOMER DEFINED FUNCTIONS
