init.d script won't show [ OK ] message.

[ploceus]

Hi.

I have script named "foo" in /etc/rc.d/init.d so I can start/stop/restart it.

When I write
# ./foo start
Starting server a.out:

And thats it.... I do not see [ OK ] message on the right and there's no shell prompt.

a.out is a perfectly valid small sample program, so what is missing here?

On the other hand if I replace my sample program with another application, then I do see the [ ok ] message. So the foo script is correct.

It seems that I'm missing some message or signal passing mechanism in the sample program, but have no idea of what it is.

Any suggestions?
Thanks

Those spiffy messages are functions that are defined in /etc/rc.d/init.d/functions. Here's an example of how I use them in /etc/rc.d/rc.local:

[gene@Mobile-PC init.d]$ cat /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

# Run the acpi ac adapter script in case the machine booted on batteries.
# Loading the governors at boot also makes them show up in the desktop
# CPU frequency scaling monitor applet.

# Source the init.d function library.
. /etc/rc.d/init.d/functions

log_msg="Initializing AC adapter acpi action"
logger="/usr/bin/logger -t rc.local "
ACAD_acpi_action="/etc/acpi/actions/ac_adapter.sh"
RETVAL=0

echo -n "${log_msg}: "
[ -x ${ACAD_acpi_action} ] && ${ACAD_acpi_action} || RETVAL=$?
if [ ${RETVAL} -eq 0 ]
then success
    $logger "${log_msg} succeeded"
else failure
    $logger "error: ${log_msg} failed with exit code ${RETVAL}"
fi
echo

touch /var/lock/subsys/local
exit ${RETVAL}

The first highlighted section loads the functions. The second section starts the line of text in /var/log/boot.log or your terminal. The third and fourth sections (success or failure) print the [ OK ] or [ FAILED ] part of the message. The last echo prints a new line.

P.S. The logger stuff puts entries in /var/log/messages.

dd_wizard,

Thanks for your reply. Your message helped me solve the problem. The problem was that my sample program was not daemonized. After I enabled my sample program to fork and detach from the parent process, I can see the [ OK ] being printed upon starting and restarting the foo script.
