Can anyone tell me how to add lines in one file by another bash file?
I make a script to change governors and frequency but I need to make the setting set on boot (But I dun want use 3rd party app like SetCPU).
So I need to add these lines to init.d folder's file :
Code:
#!/system/bin/bash (and i add line but this is by default?)
echo "interactiveX" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor (if the next time i chg setting , will this line be deleted or there will be another line with new setting?)
echo "800000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo "245670" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
so what command should i use to add these line ?
Code:
#!/system/bin/sh

thanks for your reply but i dont really understand...
those '800000' , '245670' and 'interactiveX' are just some example
i mean i want to write this:
echo "800000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
in init.d folder's file by other file
this file is in /system/bin
so i can access and chg my cpu setting by typing 'cpuclock'
there for i need a command to add line to init.d in order to set on boot
Code:
echo " Change CPU Governor Profile "
echo ""
echo ""
echo " Current Governor: "
echo "$CUR_GOV"
echo ""
$sleep
echo " Available Governors: "
echo "$AVAIL_GOV"
echo ""
$sleep
echo " Insert your desired governor: "
echo -n " Your Governor: ";read GOV
echo $GOV > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
[COLOR="Red"][so now i change my current governor,but the governor will be reset to default(ondemand) after next reboot]
[all i want is , while echoing current governor , i need to add one line to init.d there too , but i don know how :(][/COLOR]
echo " Complete "
echo ""
$sleep
echo -e " Current Governor: "
echo ""
echo ""
$sleep
echo -n " Press Enter Key To Continue... ";
read enterKey
opt=0;;
asd
Is this what an overclock init.d script should look like?
And how would you know if it worked?
#!/system/bin/sh
echo 245760 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo 1000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo "performance" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governer
echo "sio" > /sys/block/mmcblk0/queue/scheduler;
If no one can tell me if I'm in the right direction or not is there a way to see if the script is working in the init.d?
If I use this:
cat > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
it still shows the default and not what I put it too.
Do I have to edit the kernel before making a script?
How can this be done properly?
The kernel needs to support overclocking before anything, if you're confident with kernel development then do that and try an o/c app from the market before using a script.

Okay guys, I made some kernel tweaks that work on any ROM, and on the ROMs I have tried, improve battery life/performance.
THE BATTERY SAVER SCRIPT WILL NOT IMPROVE QUADRANT SCORES!
THIS SCRIPT WILL BE UPDATED FREQUENTLY!
Last update 7/11
Latest update notes: Focused more on battery life.
Battery stats on Liquid Smooth 1.5 with script:

IF THESE SCRIPTS DON'T WORK, USE THIS ONE.
Find them HERE
STEP 1. Under File, select DOWNLOAD.
STEP 2. Find a way to get it to your phone,make sure it's not opened in any text editors, until it's on your phone.
STEP 3. Follow other instructions

Latest update notes: enabled ZRAM(compressed RAM), loads SIO I/O if available, also loads the hotplugx governor and SIO on boot. Ups read and write speeds all around, file system speedups, enables multi threading, tweaks to the hotplug and hotplugx governor, and more. You might get random reboots using this script, you might only get a coupke and then they will stop or they'll never stop. Inform me if you consistent random reboots.

You will definitely see a boost in performance when running the following script.
For this to work, either run this code at boot with an app like ROM Toolbox.
Or run the attached file at boot with an app like Script Manager.

Your link is broken
This can be added to my BootMenu boot script.
Do have any details on what each line improve??
maybe add comment before each line

I might comment this in the future, but I don't have the time right now. I'll fix the link to the forum in the morning, the script download is operational.
I'll suffice it to say that these tweaks make the kernel write to disc less, using less battery, but decreasing performance.

So far: Running your script, CPU set to 800mhz max, felt no performance decrease. We'll see how this works in the future. Battery drain on EU kernel is terrible. I hope this helps a bit. Thank you!

Yeah, us OG RAZR guts have to deal with crappy battery life. That's why I made this script, please post your findings.

Can you make and update.zip that makes the script works?If this is possible ;s i'm a little newbie

Unfortunately, I don't have the skill to do so, if somebody with this skill would like to put together a flashable .zip, then I would be grateful.
Script updated, now has kernel tweaks for performance!

sorry, a little question from noobs...
it should run both? or just pick one of it?

Just pick one, they contradict each other in values, so if you try to run both there will be issues in what gets applied.

it would be useless, since you have to run the script each time you reboot your phone.

Use the option in Script Manager to run on boot. Then reboot your phone. And the values will be applied.

The updater script would probably look for an Init.d folder and run it from there on every boot, if it was there anyway.

Some feedback: there are really improvements in battery life! Now I can rum the EU leak with 3G all the time and it doesn't eat the battery that much... No performancy decrease so far..

But ive just charged it 3 hours ago and iam using it all the time. Screen on is 2 hours.
This is an older one without tweaks...

Your kernel tweaks, they are like governors? If so why is it not possible to have smartassv2 for example?
As well, did you started to work on this because of this?
Anyway, good job and I'll let you know about my experience with your tweaks =)

Governors are different to tweak scripts. A governor drives the CPU directly to its needed configuration, speed on processes or things like that. This script makes the kernel working different on some processes.
---------- Post added at 12:05 AM ---------- Previous post was at 12:02 AM ----------
@OP: You added a second script. Can we run them both or better one of them alone?

Just run one at a time, they contradict each other in values. And the performance script is going to be getting an update later today.
I have some scripts in my init.d folder, but when i check it on init.d log file.. it doesn't work. I do same as tutorial that i got here.. but it said "nonexistent directory" . Is there anyone know why?
I still confused because two of my scripts (zipalign & loopy_smoothness) are working.. but not for the other..
Here one of my tweaks :
#!system/bin/sh
echo "64" > /sys/module/lowmemorykiller/parameters/cost
echo "0,1,2,4,9,15" > /sys/module/lowmemorykiller/parameters/minfree
echo "0" > /sys/module/lowmemorykiller/parameters/debug_level
The log file said " nonexistent directory "..
