[SOLVED] rc.M script syntax changes between 12.0 and 13.37, rc.apcupsd scripts has exit 0.

I am having problem with rc.M script. example

Code:

 
# Start the local setup procedure.
if [ -x /etc/rc.d/rc.myscripts ]; then
  /etc/rc.d/rc.myscripts start
fi

without . and space in front /etc/rc.d/rc.myscripts start this line will automatic load during boot process(13.37 64bit system) but if I add .

Code:

 
# Start the local setup procedure.
if [ -x /etc/rc.d/rc.myscripts ]; then
  . /etc/rc.d/rc.myscripts start
fi

this line will not automatic load in 13.37 system, but works 12.0 system, can anyone point out why and where can i get more info on rc.M scripts syntax, I am using 13.37 64bit and 12.2 both systems, thanks.

Is there any action in rc.myscripts when $1 equals "start" ?
Maybe you could post rc.myscripts ?

Code:

#!/bin/sh
# Start/stop/restart commands

if [ "$1" = "stop" ]; then
  echo "Stopping commands"
  /usr/local/sbin/commands -s
elif [ "$1" = "restart" ]; then
  echo "Restarting commands"
  /usr/local/sbin/commands -s
  sleep 1
  /usr/local/sbin/commands -d /dev/ttyS0 -S 9600
elif [ "$1" = "start" ]; then
  echo "Starting commands"
  /usr/local/sbin/commands -d /dev/ttyS0 -S 9600 
fi

yeah, "$1" = "start" in a if conditional selection, very simple and rudimentary scripts

I think I figured out why, installed slackbuild apcupsd, the rc.apcupsd scripts has exit 0 at end. comment it out, fixed bash . source command for rest of rc.M file.

If scripts have exit 0 at end of bash script, it will properly exit, don't need to add . source command in rc.M script to call up this bash script. otherwise, it will force exit rc.M in the middle.
