[SCRIPTS][INIT.D] KangBang Kernel [DEVELOPMENT] - Galaxy S II Android Development

KangBang Kernel Scripts Development
This thread is dedicated to the development of bash scripts to control several aspects of KangBang Kernel.
The scripts below, are there for that. most of the work have been done already (but more additions to be made), but be are with problems on the logs files... the output indicates that the scripts are giving errors...
these are scripts so far​

S91 is partially working, it sets the correct governor, speed, voltage and i/o scheduler, but gives other errors...
S92 no sure. zipalign binary seems to be doing its job, but strange output on log...
S93 seem to be working, sometimes it gives an error about *db being locked" or "permission denied" ...
S94 not working. lots of errors on log...
S95 is working properly.

We appreciate ALL the help we can't get from the XDA community..
This is a fantastic kernel compilded and mantained by @sakindia123, but there aren't lots of options to control it, besides the init.d scripts...
So please, if you have suggestions, corrections and additions to be made, please do so ! ​

Thank you for the topic. As i'm very new to kernel scripting would you mind explain what exacly each script is designed for?
Thank you in advance

Nice idea mate!
A small tip/request: can you put the scripts inside spoilers?
Could be much easier to search for what we need

ive attached the scripts that i use in my roms to be placed in the init.d folder. the zipalign file needs to go in the system\bin folder and sqlite3 goes in the system\xbin folder

many thank for your contribution !!
just a quick (and maybe silly question) .. normally on all zipalign scripts the binary goes to pah /system/xbin .. is it the same thing, or in the future i may have problems, using same some scripts that use zipalign or something for ex..?

ive had no problem with the zipalign binary being in the system\bin folder. the log shows everything completes successfully without any errors. i dont think it matters too much tho

Just we wondering if there is a script for turning off the menu and back button lights after 3 seconds or so and for then to turn on when you touch the screen.
I set it using the settings in advanced/display but they are either always on or always off?
Thanks for any help :thumbup:

I copied the script into notepad++, I save as an .xml? Like S95bln.xml?
Then copy the script to system/etc/init.d and reboot and voila???
Thanks for helping! I really do not understand all this scripting !

You dont need to change anything on the script. Just place it on init.d folder and set permissions to 0755. NO extension to the file!

The directory of /data/log is empty?
Does this mean the script has not run? Any idea how I get it going as the behaviour of the leds is still the same!

If don't have this file: /data/log/bln.log , then the script not run.
Do you restart your phone?

Yes I just restarted my phone and checked the directory, empty!
What should I do to get it working?
Edit. Got the script to run at boot, but it still doesn't work.

Edit
I was looking at the directory /sys/class/misc/backlightnotification/enabled.
On my Rom - SentinelROM it looks like this directory is symlinked to /sys/devices/virtual/misc/backlightnotification
Just wondering if this would impact on the script and why it says "No such file or directory" as the error??
