Thema: What script does OpenATV use to start enigma2?

Hello,

I am using minisatip on a linux box running OpenATV 6.3.

On boot up I would like to prevent enigma2 from starting and just start minisatip instead... or else maybe stop engima2 if it is running and then start minisatip. I have looked at

Code:

/usr/bin/enigma2.sh

but I'm not sure does that script actually start enigma2?

This script will stop enigma2 if it is running and start minisatip... but I'm not sure where I should put it.

Code:

if [ -f /home/root/no_enigma ]; then
if [ `ps ax|grep minisatip|grep -v grep|wc -l |awk '{print $1;}` -gt 0 ]; then
exit
fi
killall minisatip;sleep 2
killall enigma2
cd /home/root
./minisatip -l -l --dmx-source 0:0
exit
fi

In fact I would prefer to stop enigma2 from starting in the first place if possible.

Any help much appreciated!

Well I spent a few days on this and briefly here are my findings...

Yes....... /usr/bin/enigma2.sh IS the script that controls how the /usr/bin/enigma2 program starts.

I got my Amiko Alien2 box to start minisatip on boot up by replacing the contents of /usr/bin/enigma2.sh with a script that checks for the existence of a file in another directory... /home/root/no_enigma
If this file was present then the new enigma2.sh script started minisatip else it started enigma2 as normal, like this:

Code:

#!/bin/sh

# Check if the no_enigma file exists
if [ -f /home/root/no_enigma ]; then
	# If enigma2 is running then kill it
	ENIGMA_PID=$(ps ax|grep -w "/usr/bin/enigma2$"|grep -v grep|wc -l | awk '{print $1}')
		if [ "$ENIGMA_PID" -gt 0 ]; then
			echo "enigma2 is running, killing it now"
			current_time=$(date "+%Y.%m.%d-%H.%M.%S")
			touch /home/root/Killing-enigma2-enigma2.sh-$current_time			
			init 4
		else
			echo "enigma2 is not running"		
		fi
	# Check if minisatip is running already, if not then start it
	MINI_PID=$(ps ax|grep minisatip|grep -v grep|wc -l | awk '{print $1}')
		if [ "$MINI_PID" -gt 0 ]; then
			echo "minisatip is already running"
		else
			echo "minisatip is not running"
			echo "starting minisatip"
			current_time=$(date "+%Y.%m.%d-%H.%M.%S")
			touch /home/root/Starting-minisatip-enigma2.sh-$current_time			
			/usr/bin/minisatip --satip-xml http://127.0.0.1:8554 -R /usr/share/minisatip/html		
		fi
else
	# The no_enigma file does not exist or has been re-named
	# Check if minisatip is running, if yes then kill it
	MINI_PID=$(ps ax|grep minisatip|grep -v grep|wc -l | awk '{print $1}')
		if [ "$MINI_PID" -gt 0 ]; then
			echo "minisatip is running, killing it now"
			current_time=$(date "+%Y.%m.%d-%H.%M.%S")
			touch /home/root/Killing-minisatip-enigma2.sh-$current_time			
			killall minisatip
		else
			echo "minisatip is not running"
		fi	
	# Check if enigma2 is running already, if not then start it
	ENIGMA_PID=$(ps ax|grep -w "/usr/bin/enigma2$"|grep -v grep|wc -l | awk '{print $1}')
		if [ "$ENIGMA_PID" -gt 0 ]; then
			echo "enigma2 is already running"
		else
			echo "enigma2 is not running"
			echo "starting enigma2"
			# See explanation in below link for the.... > /dev/null 2>&1 & bit!
			# shell - What does "2>&1" do in command line? - Super User
			#/home/root/run_enigma.sh > /dev/null 2>&1 &
			current_time=$(date "+%Y.%m.%d-%H.%M.%S")
			touch /home/root/Starting-enigma2-enigma2.sh-$current_time			
			#nohup /usr/local/bin/run_enigma.sh > /dev/null 2>&1 &
			/usr/local/bin/run_enigma.sh
		fi
fi

The file... /usr/local/bin/run_enigma.sh simply contains the exact same content as the original enigma2.sh

But in fact I then ended up reverting those files to the way they were and creating another script than presents a menu to allow you to switch between running just enigma2 and just running minisatip, like this...

Code:

#!/bin/bash
#================================================================
# This script is intended to be executed when Alien2 is already
# running and you want to switch between enigma2 and minisatip 
#================================================================
## ----------------------------------
# Step #1: Define variables

EDITOR=vim
PASSWD=/etc/passwd
RED='\033[0;41;30m'
STD='\033[0;0;39m'
 
# ----------------------------------
# Step #2: User defined functions
# ----------------------------------
status(){
	enigma_pid=$(ps ax|grep -w "/usr/bin/enigma2$"|grep -v grep|wc -l | awk '{print $1}')
		if [ "$enigma_pid" -gt 0 ]; then
			echo "Enigma2: Running"
		else
			echo "Enigma2: Not Running"
		fi
	mini_pid=$(ps ax|grep minisatip|grep -v grep|wc -l | awk '{print $1}')
		if [ "$mini_pid" -gt 0 ]; then
			echo "Minisatip: Running"
		else
			echo "Minisatip: Not Running"
		fi
}

pause(){
  read -p "Press [Enter] key to continue..." fackEnterKey

# do something in one()
one(){
	echo "Run minisatip only"
	# If enigma2 is running then kill it
	enigma_pid=$(ps ax|grep -w "/usr/bin/enigma2$"|grep -v grep|wc -l | awk '{print $1}')

			echo "enigma2 is running, killing it now"
			#current_time=$(date "+%Y.%m.%d-%H.%M.%S")
			#touch /home/root/Killing-enigma2-satip-$current_time
