[BASH SCRIPT][UPDATED] Governor Switch Scripts from the Command Line

UPDATE: Govswitch.sh has received an upgrade and it can now automagically generate an init.local.rc.new which can be used to set a governor on start up. It will also generate the chosen governor specific script and place it in the /system/bin folder. Thank you Duffkitty for the idea!
Original Post:
In the spirit of Open Source, I've written a couple of scripts that I wanted to share with the community. These are meant for advanced users familiar with the *nix command line. I didn't want to buy SetCPU (yes, I'm cheap ) so I decided to automate the process through the Bash shell language. For those interested, I've written a couple of Bash scripts that allow you to switch CPU governors via the command line. One script generates single instance scripts (one per governor) that can be used in conjunction with GScript for single click governor shortcuts. These single instance scripts are also ideal for changing the governor at boot. The other is command line only and prompts the user to choose from the available governors on the system.
I got tired of having to type it all out so I scripted the process. I just wanted to share with everyone else. I'm also planning to write a watch script that changes to the powersave governor automagically if the battery gets low.
I hope someone finds these scripts useful. Please let me know if anyone finds any errors in the scripts.

If you do not know what this does, please do not use it.
Despite my harsh warning above, I've designed these scripts to be as failsafe as possible so that nothing is written if the user does not want changes or the governor being selected is already in use. I use these scripts all the time and I have tried to make them as user friendly as command line scripts can be.

govscriptgen.sh
Description: This script generates a set of scripts, one per governor to '/sdcard/governors/'. If a governor is not available in the kernel, no script is generated for it. IE: You can't have ondemand on a kernel that only has interactive built in as the only governor. If you do happen to run a governor script for a governor that is not available, it will simply exit with an error message and no changes made.
Example:
Run:
Code:
bash /sdcard/govscriptgen.sh
Then:
Code:
bash /sdcard/governors/ondemand.sh

Please let me know if you have any questions.

At first I got a yesno error but ran it with sh and not bash.
Working but I can't figure out gscript it sends out stderr's. I have the lite so dunno.
I'm guessing to start at boot I would need to edit a bit =P

I found this for running scripts at boot. It's a good place to start.
http://forum.xda-developers.com/showthread.php?t=690564&page=2
govscriptgen.sh
This script generates a set of scripts, one per governor. It's those scripts you would want to use at boot or in gscript. If you didn't change the location, and assuming that you could write to your SD Card, they should be located in '/sdcard/governors'. There will be one per available governor (this is dictated by the kernel configuration).
In GScript do the following:
1. Open GScript Lite.
2. Menu > Add Script
3. Name the script. Let's say Ondemand.
4. Check 'Needs SU?'
5. In the text box type (without quotes), 'bash /sdcard/governors/ondemand.sh'
6. Create a shortcut to that script and it will set the governor it is named for.
govswitch.sh
This one is for use in a terminal and prompts the user for the desired governor.

I think I figured out and was gonna post it but you already did thanks. I appreciate it.

I think it needs the interpreter in front of it. Could you try the following?
Code:
service gov_interactive /system/xbin/bash /system/bin/interactive.sh

I'm glad it worked. Yeah, Android's command line fought me most of the way until I learned to just call bash before running any scripts. I suspect it's probably because the command line on Android initializes in a relatively 'bare' state as compared to all of Linux's bells and whistles that I'm used to.
Let me know if you have any more questions.

Thanks for helping =) I wonder if its possible to add bsd style init scripts. I guess you don't actually need to change many services but an rc.conf file would be cool =P

I started on Slackware and a '/etc/rc.d/rc.local' file would be really awesome. Slackware being one of the oldest distros (if not the oldest) is very similar to BSD. I've had to configure Slack many times, but once you did it was rock-solid.
Android feels more like Ubuntu in some ways and Red Hat in others, but a very slim version of either. I can't really explain it.
Anywho. Glad I could help.

How did you write this script one month in the future?
Seriously....would this script be able to change kernel voltage from command line? Say changing from undervolted to regular voltage for certain tasks (like GPS nav for example), then switch back to undervolt for other usage? Is something like that even possible? I've seen a few others ask about something like that in other threads.

If there is a command line associated with it, I can write a script that can easily handle it. I haven't looked into the specifics on changing voltages...
TBH: That thought scares the bejeezuz out of me.

These are kernel level calls that have to be compiled into the kernel. Unless they make this available as a system variable, like the governors are, I don't think changing the voltage from the command line is possible... or even safe. The governors are routines written to control different CPU modes of operation and are designed to be fairly safe to use in instances of power management. Adjusting the voltages from the command line would prove to be too close to suicidal because Bash can't operate at the speeds necessary to monitor voltage fluctations.
Example: We hit a voltage spike, which needs to be corrected in nanoseconds (billionth of a second), Bash would brick the phone by not responding until at least 50 milliseconds (thousandth of a second) later, if ever.
Now if they had modules written that the kernel had different voltage 'modes' and built-in safeties, then I wouldn't have a problem manipulating them from the command line. As it stands, I'll leave it to people who think in ARM Assembler, C, and C++. lol

However, I am taking script ideas, so feel free to suggest anything else you might think is useful.

Govswitch.sh has received an upgrade and it can now automagically generate an init.local.rc.new which can be used to set a governor on start up. It will also generate the chosen governor specific script and place it in the /system/bin folder. Thank you Duffkitty for the idea!

hi TopDroid. After flash v1.3 on A8 i saw that my phone doesn't goes too smooth as V1.2 on A7. it lags and i have to wipe dalvik cache so usual, ram memory usable is less than v1.2 on a7 too. Moreover, can you make transparent status bar or hidden status bar by cwm flash file? much appreciate and thank you.
P/S: apps and settings i use the same on A7, I did clean ddfl2 by odin, wipe and flash fresh A8 (original of Dhiru1602). Thank you.
Edit: I install fresh all apps, i do not back up and restore.

Use v1.2 if you find it better. Totally up to you!

lola file is just update the build.prop so it's work on All rom with 4.2.2 JB , And Topdroid file it's just replace Stock Alpha8 build.prop to new one so it's work only on A8 ..

Really nice script. But the reason I'm not using it is that your script will add the build.prop tweaks to the existing build.prop and mine will completely replace it. The problem with your script is that if the existing build.prop already has been tweaked, there may be a possibility of duplication and that can create problems.
I'm not being disrespectful but expressing my view.

With this tweak i face the same problem as turbo charge. Blacklist still vibrate and play ringtone even number was blocked.

10.2?

[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)

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.

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

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.

{script} self-repair important data

Hello my goal is to create a buckup/restore script that does the restore from a safe file on phone when some files are missing or damaged in some way .
So i need help to get it started
By my idea it should have already a prebuilt backup file from which it will restore missing files
So after flashing a zip or at boot it should always run and check if something is missing from specified location example system/etc/init.d
And when it finishes it should react if there are files that are missing or are damaged
For the files that miss that is simple but how to create a script that will check if the file is damaged
simple by checking it size
ok i know how this would work in theory but i dont know how to writte that kind of a script so please
help thank you i made a simple check files script here:
Code:
#!/system/bin/sh
clear
sleep 2
echo ""
echo "SPL ENGINE CORE is installed "
sleep 2
echo ""
echo "Checking for SPL ENGINE A.I. CORE ..."
sleep 1
if [ -e /system/spl_engine_1996 ]; then
echo ""
echo "SPL ENGINE CORE is installed..."
sleep 1
else
echo ""
echo "SPL ENGINE CORE binary was not found,please Re-flash SPL Transcender then try again!"
sleep 1
fi
but how to backup restore from backup folder if it is missing or damaged dont know please help me
this is an idea about a smart self repair script so dont abuse and help
latest code not working but an improvment i think
Code:
#!/system/bin/sh
clear
sleep 2
echo ""
echo "SPL ENGINE CORE is installed "
sleep 2
echo ""
echo "Checking for SPL ENGINE A.I. CORE ..."
sleep 1
if [ -e /system/spl_engine_1996 ]; then
echo ""
echo "SPL ENGINE CORE is installed..."
sleep 1
else
echo ""
echo "SPL ENGINE CORE binary was not found,please Re-flash SPL Transcender then try again!" then
cp ./system/data/secure/files/spl_engine_1996 ./system
sleep 1
fi
found the solution for the copying eror it gave its in this line
looks like this :
Code:
cp ./system/data/secure/files/spl_engine_1996 ./system
and it should look like this:
Code:
cp -rf ./system/data/secure/files/spl_engine_1996 ./system
Two more things left:
1.make it run at every boot or for at a specific time 3 days a week
2.make it check if files are damaged
theese two steps will make it like artificial inteligence
hi i made some changes but i keep running into erors
the script now looks like this
Code:
#!/system/bin/sh
clear

Modifying a 2/2 XL script for the 4/4 XL

Hi all,
You may or may not already be familiar with it, but there was a very nice script created by Joseph Miller to install new factory images (with or without locking the device). What I would like to do is to see how much of the script can be migrated to work with Pixel 4/4 XL.
Based on your experience with updating your 4/4 XL, do you see anything in the deuce script for the Pixel 2 that would need to be revised for use on a Pixel 4?
I'm certainly willing to test on my own device and any feedback would be appreciated. (I am relatively new to the Pixel 4 XL but very familiar with the Pixel 2 XL.)
.sh version is below:
Code:
#!/bin/sh
echo "Welcome to Deuces Flashing Script!"
echo "v5.0-Linux"
#to create a log, run: "script -c ./deuce-flash-all-v5.0.sh logfile.log"
echo "Checking if Fastboot binary is accessible.."
if [ -f "fastboot" ];
then
echo "\033[32m fastboot binary exists in script directory.\033[0m"
fb="./fastboot"
else
echo "\033[33mfastboot binary does not exist in script directory\033[0m" >&2
command -v fastboot | ( read fb; echo "\033[33mFound $fb. Will try to use this.\033[0m" )
fb="fastboot"

echo "Checking if Fastboot works correctly"
if $fb --version

.bat version is here.
Note: I recommend placing the latest flashboot somewhere in your $PATH and running the script from within the unzipped factory image folder (where you have also unzipped the image zip).
Edit: Updated deuce script to v5.0 (thanks quorn23!)

Just a heads up, you're using an older version of the script, see original thread https://forum.xda-developers.com/pixel-2-xl/development/tool-deuces-bootloop-recovery-flashing-t3704761
I haven't tested it yet, but the 5.0 apparently works with A10 skimming through the last few pages in the thread. Once the Kernel is updated with the new sources (dez broke face unlock) i might have a look. What i probably would do is prepatch the boot image with magisk, besides that i would assume it's pretty straight forward, as it's AOSP.
Edit: as context, i'm coming from the pixel 2xl as well, i generally been using the Deuce script to update the 2 XL, if i recall correctly the only change i made was to adapt it to flash TWRP as well, which is currently not needed as not available for the 4 XL. (Devs wife is pregnant, so he's busy with more important personal life stuff currenty)

Click to expand...
Click to collapse
Out of habit, I've always re-added magisk manually, but you're right, this will require some additional dance steps without twrp. What i like about the original sh script is that the core dependency (for most scenarios) is a recent fastboot.
