[Q]Need assistance with init.d script - Android Software/Hacking General [Developers Only]

Hi forumers, how are you doin..
I hope that this is the right section to post my problem.
I need help to edit this script...basically its a startup script for android. here's the script
==========================================================
Code:
AWAKE_GOVERNOR="conservative"
SLEEP_GOVERNOR="conservativeX"
(while [ 1 ]
do
AWAKE=`cat /sys/power/wait_for_fb_wake`
if [ $AWAKE = "awake" ]; then
echo $AWAKE_GOVERNOR > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
log -p i -t screenstate_scaling "*** awake ***: switching CPU frequency governor to -> $AWAKE_GOVERNOR"
AWAKE=
fi
SLEEPING=`cat /sys/power/wait_for_fb_sleep`
if [ $SLEEPING = "sleeping" ]; then
#i want it to pause here (sleep 30?)the reason there is 30 sec pause is bcos i #want it to ignore the commands below just in case #"$AWAKE=awake" without #proceeding to the commands below.(or better just ignore and return to #waiting_for_fb_sleep)
echo $SLEEP_GOVERNOR > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
log -p i -t screenstate_scaling "*** sleeping ***: switching CPU frequency governor to -> $SLEEP_GOVERNOR"
SLEEPING=
fi
done &)
==========================================================
So basically, after $SLEEPING="sleeping", i want it to pause for a moment(lets say "sleep 30") because that will give it some time just in case $AWAKE="awake" occur during this period. Attached is my flow chart..im thinking of "else if"...tried cygwin to compile because im running windows but I just cant load a shell script with it even a hello world
thanks in advance..your assistance is highly appreciated

REQUEST/IDEA for a safety script for tweaking/OC

I had an Idea for a script that would run at bootup, and if a certain variable had a "value" of NOT 1.
then the script would change the CHMOD of a userinit.sh located in the sd-ext from 050 or 777 to 750 then it would change the variable "value" to 0 were it would stay untill another script that runs at shut down or reboot setts the variable to 1 and changes CHMOD back to 050 or 777 so that the userinit.sh is not run.
That way if a change is made during operating the phone that causes the phone to crash with out shutting down properly the script runs which causes the userinit.sh to run and "resets" userinit.sh values to a "default". Otherwise if shut down properly nothing happens.
This could be expanded on to include repairing the EXT or clearing some special cache or other stuff I am unfamiliar with but that you might want to run after a crash.(like logcat?)
any way what do you think? any promise?
I think, for overclocking purposes anyway, making the userinit.sh unrunnable would make the phone break immediately, as I think it would go to the highest available frequency. However, I like the idea, though I'm not sure how to run scripts on shutdown. I think for overclocking, it would check if the shutdown was clean on startup, and if not change the applicable line to the next lowest number, which it would get either from a seperate file or maybe it could be stuffed in the script itself. (Just my somewhat uneducated thoughts)

Keep it simple. If a change in userinit.sh breaks your system, reboot to recovery and edit it and reboot again.

most rom devs/tweakers launch userinit.sh by calling it with a sh
e.g.
/system/bin/sh /system/sd/userinit.sh
so it will still run !! ( as init doesn't care about permissions, it is god )
don't believe me?
Code:
echo "echo I ran" > /data/test.sh
chmod 000 /data/test.sh
sh /data/test.sh
Keep it simple. If a change in userinit.sh breaks your system, reboot to recovery and edit it and reboot again.

And I know that most roms now have a script called something like in /system/etc/init.d/20userinit that runs at startup and checks to see if a userinit.sh is present in sd-ext,if so it runs it.Also I noticed that the script can be there but if it is CHMOD to 777 it wont run. This is the "Reset script" Set to restet to something you like and run other tasks to help Fix/Diagnose probs.
The OC changes would be made from a different script such as 86supersettings
Or a userinit located in system/sd maybe ?
The thing is making sure one is read before the other.
Any way I probably will just learn the language better and do it from recovery console.
Thanks again

chmod 777 makes it rw and executable by everyone!!!!!!!!
have a look here
http://www.comptechdoc.org/os/linux/usersguide/linux_ugfilesp.html
but as I mentioned above, init ( the initial progam runs as root and doesn't care about permissions, ( it wouldn't be very good at doing initialising the system if it had to seek permission )
Yea your right. Well I said I wasn't that good at this linux stuff! Now I Proved it.
Any way as you can see this is more of a request..... I still think it's a good Idea.
Thanks for your help FireRat.

I understand how I could manualy Replace the modified script with a default one that was on my sdcard from within recovery after a faild OC change...but..
Are you saying I could actualy modify the original script from recover? Do you have any info on how? A link?

If you have RA-Recovery, adb works, so you can pull/push the userinit.sh script. You can also enter the terminal and use vi to edit it from recovery. You may have to mount the ext partition first, but that's pretty easy. "mount /system/sd" will do it, if /system/sd doesn't exist, "mkdir /system/sd".
Ok, Thanks that makes sense. I'm still learning adb though. And I tried vi once before with no luck. But now I know what to learn about.
Thanks a lot I appreciate it.

I am going to use the beta boot up script from ZKX called 86Supersettings, but I could use a userinit/user.conf like most do. Correct?

well, a .conf file should be just that

OK. I guess I meant both together. I would use the user.conf to make tweaks. Then have to modify the userinit.sh with the part you made. Something like.
#!/system/bin/sh--LEAVE THIS OUT. ITS ALL READY AT THE BEGINNING
if [ "`cat /data/cleanshutdown`" != "1" ];
then
echo "shutdown was not clean"
Dont run user.conf
and set cpu or other stuff to "default"
else

Run user.conf for tweaked settings

If I'm way off then I guess I need to re-read the Userinit thread.

well, in practise it doesn't matter
the file extension is only for use humans, if I'm looking in a directory and I see .conf I expect it to be a configuration file, I see .sh, its a shell script, .py python, pl perl .......
I see. Well Thanks again for your help. Your script does work. I tried it. crash on purpose.
I still have a lot to learn.
Folks;
1) If you're OC'ing via SetCPU, remember that this doesn't change the recovery kernel, and you can uninstall SetCPU from Recovery. From there, all you need is a "safe" userinit.sh.
3) If you're OC'ing via userinit.sh -- same deal. Your phone crashes on you and you just edit it to a safe config from recovery.
Tweak away.
This is what I ended up with

Named 86supersettings so it runs after userinit.sh if one exists.
I put some Led indicators in so you can tell if it ran right at boot up. (about all I did besides copy and paste) Thinking about adding some other stuff like repair ext, or some kind of log to help me see what happed... any suggestions.
OK, here's another Idea for another safety feature...
I would like to "hard code" a temp fail-safe in to the code. I would like to get rid of SetCPU and when OC-ing it's nice to have a temp failsafe.SHUTDOWN!LOL
Any way I guess I would just add a few lines to some existing script in my phone?.... Any suggestions.
Thanks for your time.

[KERNEL] conservative governor for HTC 2.6.32-15 kernel

This module adds to the kernel the possibility of using the 'conservative' scaling governor. It may be a little less responsive than other governors, but may also result in better battery life overall.
This is from the kernel documentation:
"The CPUfreq governor "conservative", much like the "ondemand" governor, sets the CPU depending on the current usage. It differs in behaviour in that it gracefully increases and decreases the CPU speed rather than jumping to max speed the moment there is any load on the CPU. This behaviour more suitable in a battery powered environment."
By default it will try to increase or decrease the CPU in 5% steps, and will tend to raise relatively slowly under load but decrease very quickly when idle. This means the CPU is likely to spend much more time at the lowest frequency (245MHz unless changed), but will offer the highest frequency when required for a longer period (like watching video).
The module in the attached files is compiled for the 2.6.32.15-g6a358a9 HTC kernel (released with 2.10.405.2) and the -gf9c0527 kernel (2.09.405.8).
To load, copy the module in recovery to /system/lib/modules and run:
insmod /system/lib/modules/cpufreq_conservative.ko
And to select run:
echo "conservative" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
The attached update files will either load the module only, or load and select the module (active version).
Source is unmodified from the original, and thus is GPL compliant.
Hmm, great . On leedroid , waiting for yur flashable file
Sent from LeeDroid powered by HTC Sense using XDA App!
Thanks for sharing, it's great
Thanks..will try it
with kind regards...Alex
Tested and it runs fine for me. Sure enough you can see the CPU go up and down gradually as expected if you monitor it.
I've added a version for the -gf9c0527 kernel too. 'Active' versions will select this governor if flashed - custom ROMs may override this, so check your ROM.
I have added it for version g1fc4045, .ko only
cpufreq_conservative_gd96f2c0
added for version gd96f2c0, .ko only
How about g1fc4045?

i want to make that when the phone is awake 'conservative' scaling governor will run.
Thanks.
You'd have to change AWAKE_GOVERNOR="ondemand" to "conservative". But that is a heavily hacked script and may not work ideally.
how can i test if the module is working?
Hi
I upgraded my phone to the latest OTA (FPS fix) with a vanilla ROM.
The kernel version my phone is running is: 2.6.32.15-ge2fb08e [email protected] #11
Currently from what SetCPU tells me, my only supported governors are:
ondemand, userspace and performance.
Any way for me to add conservative to my kernel for use with SetCPU?
Thanks
Sheldon
Anyone can make the mod for the 2.6.32.15-g5d39305 kernel? (AuraxTSense_7.8.1)
Thanks!
PLEASE!
or at least anyone can explain to me how do i make it myself? Thanks.
please help me make this file.
2.6.32.15-gf5a401c kernel from 2.29.405.2 update
is there conservative goverenor for 2.6.32.15-gf5a401c kernel from 2.29.405.2 official HTC Desire update ?
Tnx.
i'm running dj droid rom 2.29 based, and it has conservative.

As per my findings, snake charmer is Faux's application thingy. But I will definitely take a look.
Has established, but my options which were before application Faux123 Kernel Tweaks have not changed.
Glad to see you here!!
Thanks
The app costs $4.99, which is kind of pricy.

dont think his going to be very happy when he sees this lol
Heh $4.99 is nothing for what our devs do for us

i personally bought all of his apps even though i don't use them all, devs need support, threads like are kind of inappropriate and unfair.

Excuse me? In what way? Have you even looked at the file? There's absolutely nothing in there that anyone fooling around with their own init.d file couldn't have done. There is no custom code written in there by faux that someone else couldn't independently have written. Should he be credited for it? Absolutely. Is he owed any compensation for this? I really don't think so. Those who want to contribute (and make no mistake, his kernel is pretty great) can do so by purchasing his app or donating to him.

Friends these tweaks are all over the XDA forums including the Faux's kernel threads. I have only consolidated them. Btw I myself own Faux applications and they are great, of course.
This is not a place to fight rather it's a place to share knowledge. So calm down.

Well friend, you are right I thought of posting my init.d to that thread but I am not sure why I posted a new thread (there was a some reason, I forgot). Anyways I will post a link referring to this thread.

[FIX] Bricked kernel fix for kernel tuner users

Some people that used kernel tuner had some problems with kernel tuner! it worked good for sometime but after a specified time the min freq would stick to 918 mhz(boost freq as showp has explained) for both cores and not switching lower! This would make my phone very warm and drain my battery very fast! so i came up with a solution to reset the cpu min freq when you turn on/of your screen! This script i have made has worked very good and battery is in its best with this truly beast kernel! To install the script:
1.copy it in your sdcard
2.save it to a file like S98bricked_fix
3.push it in /system/etc/init.d
4. change permisions
5. reboot or run from terminal emulator
su [enter]
exec /system/etc/init.d/S98bricked_fix [enter]
6.while in terminal emulatur turn on off the screen to see if the script works! you should see cpu freq fixed and after turn on cpu freq refixed!
Ps:Kernel tuner is not needed in this kernel
The script:

its not a sh script its a binary! you can change the name to smth like fix push it to system/bin
and call it with an init.d script liike
#!system/bin/sh
fix
EDIT:ill post a new version with led notification to notify when the script is running, tomorow!
Can't call it

are you sure you set the right permisions rwxrwxrwx??
Alternative would be to use SetCpu and just activate profiles. But this is cool too for those Kernel tuner fans.

[SCRIPT][UPDATED 03.26.14] Fix Lag, Defrag/Free Memory with |=>TrimDropOff<=|

Updated 03.26.14 - Released v2.1 - bug fixes and code cleaned
Introduction:
I am by no means a developer. I am just an android enthusiast who has learned a bit of bash. The reason I made this script was that settings>>wifi>>advanced was not promptly turning wifi off when my device would sleep; sometimes it would not turn off at all. So I figured since I am making a script to resolve this issue I might as well add a couple of other functions as well. To this end I noticed some people saying THIS APP was helpful and I missed the Flush-O-Matic script from V6 SuperCharger so I added fstrim and drop_caches=3 to the script.
Click to expand...
Click to collapse
What will this do?
The script will allow you to sync wifi, fstrim, and/or drop_caches=3 with sleep and/or it will allow you to schedule fstrim and/or drop_caches=3 using crond. The scheduling option can work on either a hourly (you can choose to run desired programs every hour on the hour, every two hours on the hour, every 3 hours on the hour, etc) or daily basis (you can choose to run desired programs at a given time on the hour).
Both the sync and schedule options will load themselves in to memory each boot and each time your device goes to sleep and/or when scheduled the scripts will depending on your options: (1) sync your data so as to ensure no data is lost; (2) TRIM your /system, /data, and /cache partitions; (3) DROP CACHES = 3; and (4) turn off wifi.
In addition, there is also an on-the-fly script to manually trim partitions and drop caches when desired.
Click to expand...
Click to collapse
Benefits:
Reduce lag/improve i/o efficiency (see THIS and THIS).
Although android automatically invokes fstrim when certain conditions are met, these criteria could seldom if ever be met depending upon your usage style. The init.d script should ensure fstrim is invoked more frequently for most users.
Should use less ram than apps that perform similar functions (I say should because I have never used such apps, but I imagine they consume more that .2-.5 mb of ram).

Requirements:
root
init.d
busybox
fstrim (should be in all nexus 4.3+ roms)

Warning/Disclaimer:
Although these scripts function as intended on my device – Nexus 7 (2013), SlimKat (weekly), ElementalX...Use at your own risk. Neither I nor XDA are responsible for any possible deleterious effects.
Click to expand...
Click to collapse
Known Issues/Bugs:
If you use the sync option, scripts with a lower priority than Z99 will not execute.
The log files don't always display as intended...dunno why...any help/suggestions would be appreciated.
Let me know if you find any others .

Install, Usage/Verification, & Uninstall:
Install -
Note: If you use crond for other tasks, both the install and uninstall routine account for this potential contigency and should leave your other crond tasks uneffects.
make a nandroid backup
download the zip (<<NOT flashable) attached to this post
extract the zip’s contents
if you were/are using the first version of this script manually delete: /etc/init.d/07TrimDropOff, /data/TrimDropOff_Awake.log, and /data/TrimDropOff_Sleep.log
run TrimDropOffInstaller with superuser permission via terminal or script manager.
follow the scripts prompts
reboot
enjoy
Usage/Verification -
Assuming you have followed the install procedure, next, put your device to sleep and then wake it if you are using the sync option.
Now check the various logs in /data/TrimDropOff. The logs will show the time, the script’s PIDs, the path of the PIDs (just to double-check the PIDs are correct), the ram used by the PIDs, action(s) preformed (amount trimmed from each partition and/or if drop_cahes was run), or errors.
If you want verify manually via terminal do [pgrep -f TrimDrop] for the sync option or [pgrep crond] for the scheduling option to get the PIDs, do [cat /proc/PID/cmdline] for each PID to verify it truly belongs to Z99TrimDropOff or crond, and do [dumpsys meminfo | grep PID] for each PID to verify ram usage (this command will yield duplicates, which can be disregarded and may output undesired additional results, which can be filtered by looking through the results for the relevant PID).
To use the on-the-fly script to trim and/or drop as desired, in terminal do [su -c trimdrop].
Should you want to reconfigure your setup, uninstall before reinstalling to avoid potential issues.
Uninstall -
Note: If you use crond for other tasks, both the install and uninstall routine account for this potential contigency and should leave your other crond tasks uneffects.
Rerun TrimDropOffInstaller with superuser permission and use uninstall option at the beginning of the script.
Reboot and all will be back to as it was before.

Changelog:
v2.0
made in to installer script
added cron options
added bootloop precautions to the init.d scripts (should make it compatible with all devices that meet the requirments)
the on-the-fly script, trimdrop, now allows user to choose fstrim and/or drop_caches=3
added more syncs to further ensure no data is lost
a bunch of other stuff I probably forget
v2.1
bug fixes - fixed issue if using only sync option (missing directory); fixed display of irrelevant errors in uninstall routine
cleaned code a bit (reduced redundancy)

Credits:
Big thanks to @zeppelinrox, @dk_zero-cool, & @gu5t3r for their contributions to portions of this script (see the code of my other script SwapItOn for detailed citations).
Much thanks to @mdamaged for spotting the issue with sync init.d script and his note regarding syncing data.

Don't forget to click THANKS and RATE 5 STARS if you found this useful :highfive:.
peep my other script SwapItOn
Update to v2.1 if you were only using the sync option.
If you were using both the sync and schedule options or only the schedule option there is no need to update; the bug I found would not effect you.​
reserved...on the off chance it will be needed
Thanks, sounds interesting. I'm assuming the zip can be flashed right after flashing a new rom?

Is compatible with custom kernel? Franco in my case

Will performing trimming operations too frequently cause additional flash memory degradation?

As you were informed the zip is NOT flashable. If there is sufficient interest (say a 100 downloads) I'll make it flashable/aroma.

Yes, it should be compatible...the fstrim utility is part of the rom (it should be in all nexus 4.3+ roms).

No, to my limited knowledge it should not be harmful (in fact it should increase lifespan - google "fstrim lifespan"). Did a quick google search but could not find anything definitive/reliable regarding frequency...what I did see seemed to suggest 'no' though.
If you are concerned about the frequency, you could not install the init.d script and just use the on-the-fly script, trimdrop, to trim on-demand. Should there be interest and if I have the motivation and time, I have been thinking about making this in to an installer script and/or aroma zip with cron-based options so it could be scheduled hourly, daily, or weekly.
Scheduling options would be awesome!

Seems there is a decent amount of interest (almost 100 downloads already ...thanks peeps), as such I'll add options and make things more configurable.
Regarding scheduling, I was thinking of doing hourly, daily (with ability to choose time), and weekly (with ability to choose day and time) options. Would every other hour or some other setting be desirable?
Regarding installation, what would be the preferred method, an installer script (e.g. V6 SuperCharger) or AROMA? Flashable zips would be another option, but would have less options/be less configurable.
Gimme some feedback and I'll put something together in the next week or two depending on work and my motivation .
wasn't this a nexus 7 2012 issue and fixed in the new version 2013?

My 2 cents:
I would choose a daily option for my device.
I prefer Aroma over a script, but if you cannot get the customization you want with Aroma, then by all means go with a script.
Thanks again for the script and willingness to make it even better!
Thanks for the scripts, I time my startup, and this improved startup time by about 3-4secs, among other noticible improvements, apparently the stock OS does not run fstrim enough, initial operations freed several gigs on the data partition, and hundreds of megs on the others...

Im going to turn this into a cron job, that will take care of scheduling, unless anyone else gets there first ( please lol )
Will give it a go in its present form, whats its resource footprint just sitting there waiting for screen off ?
Can we trigger the action from the screen off event ? or some other interupt type way ?
Great script by the way, your bash is damn site better than mine, jealous lol

Yes, I think this is true to a degree...it was more of a problem on the 2012 and other nexus devices. See the links in the OP for the conditions that need to be met for fstrim to autorun...for some users (myself included) the conditions will seldom if ever be met. Also see @mdamaged post; I get similar results the first time fstrim is initiated by my script after each boot...subsequent runs normally only frees up memory on /data.

Can we trigger the action from the screen off event ? or some other interupt type way ?
Great script by the way, your bash is damn site better than mine, jealous lol

See the first post on this page and my response to @creeve4 and @imfun in this post. I will make an AROMA package with cron options for fstrim and drop_caches=3.
However, should you feel ambitious and beat me to it, props to you...I will give you full credit in the OP and link your post as the d/l source so you should get the 'thanks' too.
Regarding triggering with screen on/off or some other event: It can probably be done, but I it's beyond my knowledge (screen on/off was actually the first trigger event I looked in to using, but despite fairly extensive searching I could not find how to detect it).
Regarding resource footprint: Read the OP (usage section) it explains where to find the log which contains this info and how to do it via terminal (should you not trust me )...also see OP (benefits section): in all my testing I have never seen it use more that .8 mb, but most of the time it is less than .2 mb.
Okay will get to making an AROMA package...it will be my first, but it looks easy enough :fingers-crossed:...gimme a week or two to put it together and fully test.

Can't wait already, because after whole day or two, hard usage of my nexus 7 tablet, the tablet starts to get laggy. I can see this on web browsing, touch press delay time, and onyl rebooting seems to help... Hope after istaling this will solve the problems
ohhh no dont want any credit lol lol, i have turned it into a cron job quite simply by adding it to the cron initilising script

should drop the caches and fstrim every 8 hours, oviously set to anything you want.
i also stuck it in boot at the end

For an aroma script you will prob have to stick the file in /system/etc/cron/cron.hourly, daily, weekly and just give peeps that choice, will be most simple way. Ps not a fan of aroma lol
Ok, I should have spotted this issue right away, but did not, so here goes. It seems the use of while loop in the script in the OP causes any scripts with a lower priority in init.d to never get ran, if the script in the OP is the only one in your init.d this does not matter, nor should it matter if you have at boot script with a higher priority (they get ran before the OPs script).
I run the ElementalX kernel which depends on a init.d to initialize some parameters for the kernel, with this script in init.d they never get initialized, in my case this resulted in some things not 'taking' such as the battery life extender, which on my device, is set to stop charging at 4100mv, however, since the while loop kept the ElementalX init.d from running, it kept charging to ~4300mv, this is how I noticed (actually none of my settings wrt ElementalX were being initialized, but this symptom was most pronounced).
A simple fix would be to move up the priority of the ElementalX init.d script, but this would have to be done after each flash, and frankly since I run Tasker anyway, I saw no need for this, what I did was remove the OPs script from init.d and simply made a very simple task in Tasker to run /system/xbin/trimdrop when display goes off, it could just as easily be a time event.
Anyways, hope that helps someone who may come across this with other kernels, or other at-boot scripts which depend on being ran before the OPs script.
Again, thanks to the OP for his work. Also, I added another sync just before the drop caches, since the state of dirtyness could change after the fstrims.
