[UTIL] a2sd Updated script w/ error checking! 10/12/09

**New version in the works. See last page for my post**
**Updated 5:51pm CST**
-Made sweeping changes to the script. Thanks Farmatito for the suggestions. Output from script also goes to adb logcat
-See script for additional changelog
**Updated 11:00am CST**
-Changed a couple "cp" commands to "ln" as this is a smarter way of doing it. Script has been updated and re-uploaded
After having issues with the current a2sd script floating around (under certain environments the script would erase all user & system apps) I decided to update it so that there is proper error checking, logging, and back-out procedures on failure. The log is stored in /data/a2sd.log so if you get stuck at a black screen or it won't boot, now you can check the log and find out where its failing! By the way, if your phone won't boot or you have a black screen obviously the only way you can read the log is by connecting the phone to a pc and using adb shell cat /data/a2sd.log .
Anyways here it is, enjoy.
Procedure
Code:
adb remount
adb shell cp /system/bin/a2sd /system/bin/a2sd.bak
adb shell push a2sd.txt /system/bin/a2sd
adb shell chmod 777 /system/bin/a2sd
adb shell reboot
Everything should work like before. But you can rest at night knowing if your phone won't boot you now have a way to know if it was related to a2sd and what the cause was
**NOTE: If you get stuck at the boot screen it's probably b/c your /system/sd partition is failing the fsck. You should probably fsck it on your own to fix any corruption. If you don't want the fsck then comment it out of the script.

Very cool, lets hope a developer picks this up and uses it.

I could toss this in my next build if the masses like it (sure they will)

I was going to read through this and give a full opinion but it is too long for me to do it this late. My eyes are crossing trying to read it. But at first glance it looks good (logs are always good right ). And I've never seen shafty not do good work. I'll try to look it over in full tomorrow. Plus you've inspired me to try to think of same way to contribute to this file. So now I have to put that on my todo list.

The more the merrier. It's too bad everyone doesn't have bash installed or we'd be able to take advantage of all the features bash includes (functions, advanced iteration loops, arithmetic).
That would be on all the ROM devs to include it though. Oh and I'm a UNIX Admin so writing shell scripts is like 60% of my job. We try and make our lives easier by writing scripts to do the work for us

I figured you did something like that. Your scripts are always good. I've learned a lot from reading through stuff that you have posted. I wish I had your experience with it. I always have to fumble through to find the right syntax to do what I want to do.

Ya I started out fumbling around just as well. Keep at it and if you ever have any questions about how to do something feel free to PM me. Shell scripting, among the other 10 programming languages I code in fluently, come second nature after years of coding in them. Java/C/C++/Sh/Bash/Lisp/Javascript/Html/Php/Jquery.

Sweet, i will probably take you up on that offer sometime. I have a question about running e2fsck. I always run it with the -f option because it seems like it never finds problems unless they are really bad if I don't. Would there be a problem running it in your a2sd with -fy? I've always wondered why no one uses the -f option.

Well there's two sides to this. One could argue we should force a fsck at every boot, and then the other side is to let Android mark the partition as dirty so fsck will run only when needed. Normally the filesystem is supposed to be marked dirty if in fact it is dirty.
So if we force a fsck at every boot then that would add to the boot time of the OS but then again would ensure the filesystem isn't corrupted. It's really personal preference. It breaks down to "Speed of boot" vs "filesystem integrity"

I can't even find a2sd in cm4.1.999. Seems to have gone missing. Anyone know if it exists, and if so, where it's at?

The default location is /system/bin/a2sd . If it's not there not sure where else it could be hidden at

That's where it should be and used to be. I looked in the original zip and it's not there either. Checked sbin and xbin and other places where it also shouldn't be, and can't find it...weird.

Perhaps it was integrated into the swap file. And I don't mean swap file as in the literal swap file. I mean /system/bin/swap which is a conf file & shell script in one. I would check there to see if it was incorporated in there.

Hi,
just some comments about the "monster" a2sd script. ;-)
Hope they will help you to imprrove it further.
I would suggest to change the logging so that
it could be seen during a adb logcat of the boot process, from:
echo "Beginning a2sd `date`" >$LOG;
to e.g:
echo "Beginning a2sd `date`" | busybox tee -a $LOG;
(LOG must be initialized if it not exists)
Line 40:
e2fsck -y /dev/block/mmcblk0p2;
if [ $? -ne 0 ];
then
echo "Fail" >>$LOG;
exit 1;
fi;
else
echo "Ok" >>$LOG;
fi;
# set property with exit code in case an error occurs
setprop cm.e2fsck.errors $?;
Setprop is not executed in case of errors as we do exit. Is this intended?
Line 144:
# don't allow /data/data on sd because of upgrade issues - move it if possible
if [ -d /system/sd/data ];
then
echo -n "Found /system/sd/data which is a no-no, removing: " >>$LOG;
busybox cp -a /system/sd/data/* /data/data/;
busybox rm -rf /system/sd/data;
echo "Ok" >>$LOG;
fi;
I suggest cp -ap to preserve permissions and ownership of the copied files
I suggest to mv /system/sd/data to /system/sd/data.bak if cp fails
rather than rm all the data
Line 195:
if [ `ls -l /data/$i/ | wc -l` -ne 0 ];
then
echo -n "Moving /data/$i: " >>$LOG;
busybox cp -a /data/$i/* /system/sd/$i/;
if [ $? -ne 0 ];
then
echo "Fail" >>$LOG;
busybox umount /system/sd;
exit 1;
else
echo "Ok" >>$LOG;
fi;
fi;
I suggest to use cp -ap to preserve permissions and ownership
Line 206:
echo -n "Deleting contents in /data/$i: " >>$LOG;
busybox rm -f /data/$i/*;
I suggest rm -fR /data/$i;
Line 329:
if [ -f /system/lib/hw/lights.msm7k.so ] && [ ! -e /system/lib/hw/lights.trout.so ];
then

Unfortunately during boot anything thrown to console is not caught by adb logcat, BUT! You gave me a good idea, it will now look like this

This was already being done in the following FOR loop but after inspecting further I merged the app symlinks FOR loop with this IF statement.

Added.
Thanks for all your suggestions, I will re-upload a new version in an hour or so soon as I get a chance to change the echo commands to use logwrapper. Well I'm keeping the existing echo commands which spit output to my log but will also add another which will spit output to logcat.

I take it back, after having suffered yet another file system corruption on my /system/sd partition I'm putting that darn "-f" in there. I'll re-upload a new copy with other changes shortly

Posted a new copy of the a2sd script with lots of changes. Check it out everyone. As always suggestions & questions are welcome

Cwm - Recreate tree from .dup nandroids [Linux only]

Newer cwm's now do nandroid's via .dup files.
These files are nothing but metadata that links each backup to the real files in the clockworkmod/blobs directory.
This script merely allows you to recreate a tree from a .dup file + blobs directory. This is helpful if you want to extract a few files from a backup and not have to restore it.
link
To use :
wget -O recreate.sh http://goo.gl/wz3IU
chmod 755 recreate.sh
./recreate.sh

Totally off topic but I haven't seen you around here in years. You rooted my Nexus One for me via TeamView back when the N1 first came out.
Crazy how long ago that seems when I couldn't even root my first Android device, haha.
Anyway, sorry to go off topic.
Just wanted to say thanks all these years later. You got my going in the XDA Android scene and here I am a few years later tweaking ROMs and starting to learn to build from source.
Sent from my SGH-T999 using xda premium

Don't mention it
Glad to see it got you motivated.
Yea I don't post around much anymore. I just wrote this quick thing for myself thought I'd share it

hi. i found this thread while searching and thought it would be a really useful tool. i was having problems with my cwm6 backups and so made the following amendments to the script :
IFS=$'\n' <- added new line
while read line; do
if [ "$line" != "dedupe 2" ]; then
inc=$(($inc+1))
prog=$(($inc / $chunk))
type=$(echo $line | cut -f1) <- removed -d " "
item=$(echo $line | cut -f8) <- removed -d " "
link=$(echo $line | cut -f9) <- added new line
hashFolder=$(echo $line | cut -f9 | cut -d "/" -f1) <- removed -d " "
hashFile=$(echo $line | cut -f9 | cut -d "/" -f2) <- removed -d " "
if [ "$type" = "f" -a ! -z "$hashFolder" -a ! -z "$hashFile" ]; then
if [ -f "$blobFolder/$hashFolder/$hashFile" ]; then
cp "$blobFolder/$hashFolder/$hashFile" "$outputFolder/$item"
else
echo "No blob for " $item " found"
fi
elif [ "$type" = "l" ]; then <- added new line
ln -s $link $item <- added new line
else
mkdir -p $outputFolder/$item
fi
if [ $last -ne $prog ]; then
if [ $(($prog % 10)) -eq 0 ]; then
echo -n $prog%
elif [ $(($prog % 4)) -eq 0 ]; then
echo -n '.'
fi
last=$prog
fi
fi
this accommodated the tabs, filenames containing spaces, and links in my dup files.

[SCRIPT][v1.4]Bug Reporter (ultimate debugging) -- The MUST debugging AIO tool!

Greetings
Hello everyone, I made a script to help developers solve problems and you become a more helpful user.
What does it do?
It exports to sdcard :
dmesg
last_kmsg
wakelocks
kernel version
logcat (normal and long)
radio (aka modem log)
getprop (aka build.prop)
running processes
partition info
mount info
RAM info
interrupts
boot logs from kernels like : nAa, lupus
Total maximum possible logs are 14 files.
What should I do? :cyclops:
Send files from the folder with the time-stamp you have just created or send the tar.gz'ed file to the corresponding developer to help him. Each time you run the script it creates a different folder with a unique time-stamp of the time and date you dumped the logs.
Send whatever is needed, everything is in bug_reporter folder.
Ok, how do we install this thing?
Make sure you download the latest version [ v1.4 is the latest ] which is attached below and put it in your sdcard...and that your device is rooted.
Go to CWM recovery and flash it! It does no harm, it just copies a small 6kb file in your /system/xbin. So there is no need to uninstall it later. It will accompany you until you flash a new ROM.
If you are coming from another version, just flash it over.
If you are having any problems, first attach the debug.txt from bug_reporter folder and tell me your device, kernel and ROM. The problem might be your busybox installation though.
Ok, how do we use this thing?
Make sure you have a terminal app, I use this : https://play.google.com/store/apps/details?id=jackpal.androidterm
Open a terminal app and just type :
Code:
su
bug
IT WON'T WORK PROPERLY IF NOT EXECUTED FROM /system/xbin/, SO IT MAY FAIL WITH SCRIPT MANAGER. TRY AND REPORT BACK TO ME.
That's it?
Yes. :good:
If you have any questions, feel free to ask anything. :highfive:
Any screenshots? :angel:
Yep.

Is it possible to move this bug file to system/xbin instead of flashing it (gives error). And if yes, what should be the permissions?

It's fixed. Just flash bug_reporter[v1.0]-nAa.zip, the permissions are 755. If you are unsure about permissions, see this : http://www.draac.com/chmodchart.html
But I am telling you to flash the fixed zip, it'll work.

nice concept ,,but there are some problems
after taking log
both lastkmsg and logcat file show nothing(empty files)
long logcat shows this: 9 com.android.settings
only dmesg is correctly extracted

UPDATE!
Code:
[B]v1.1[/B]
- fixed wrong logcat exporting, now when it's disabled, you'll know it
- added an auto-check for vaccuming logs after reaching above the MB size you set (logs can easily reach 10 MB)

- terminal output logging for debugging reasons

Thanks man, I was going to write something similar until I found this.
I cannot attest to the zip's functionality as I use it with script manager, but I can say version 1.0 worked perfectly (producing the three possible proper log files) for me. Version 1.1 not so much it tells me 'I can't logcat' when I clearly can; gl with your 'main not found' problem.
Also a suggestion maybe include in your zip a copy of the script that goes to /sdcard/ so the user can easily access it in order to facilitate using it as a widget.

Indeed, logcating won't work no matter what. It's a bug. I am aware of it. I'll fix it today I guess along with some code cleanup and considering your suggestion.

Might convert this to external scripts for windows and unix as well. Btw, why the root checker? If it needs to be in system/xbin then you already have root

:victory: Yeah, do whatever you want with it!
About the root check... Have you ever thought of "just in case" case? Well sometimes sh!t happens... Like the 7+7=16 embarrassing situation on final exams for example.
Anyway, probably won't need this check on other unix systems... You'll need to start the script with
Code:
sudo -i
and remove any
Code:
su -c
in the script. Also some logging files are available only for android, like logcat and logcat radio. If you need any help with converting I can help you both for windows and unix, just PM me.
EDIT : Opss, root check is buggy, I've discovered it thanks to you! I'll upload a fixed minor revision later.

I mean set up a script to run from a pc to debug android. Let's you run it on non rooted devices (parts of it anyway)
It's quicker than getting a user to push and run via the android terminal (which not everyone has)
Easier to run via an adb interface which can be supplied, and implement an update script everyone is running the same version
Btw won't need help check my signature for the root scripts

Thanks, I'll have it in mind, the reason why I didn't do this before is that I wanted it to be simple and not so informative.
In next update I might add some colors too!

[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)

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?

Oh, thanks

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.

I didn't mean to offend OP, I didn't even complain before, because I know nothing about this. But this new version is much faster, and I assumed it was because of that. I'm sorry if I seemed rude.

I am using this script with my LG Optimus L7 P700 which has one core, overclocked to 1200 and 512MB RAM and I must say I have noticed significant improvent to memory management, lag and battery! Nice script for low end or older devices!

Read the entire thread, this is a community! we should help each other instead of acting high and mighty because you know a lot of things and you thought you knew most of the things. If you see some bugs and notice some errors why not try to help and give solutions to OP other than ranting, you knew a lot of things right? such a waste knowledge. After all, scripts and tweaks we're not made by a single person, made by exchanging ideas,self efforts and the efforts of the community.

on low end device AnTuTu benchmark v5.1 increases by +1000 keep up the good work :good:

Hi,
you have terrible mistake in your script:
file: 88Dash_Engine:
line: 208
Line not ended with ". Your script will not work and give errors.
This:
is not necesarry to do:
start at:
$( date +"%m-%d-%Y %H:%M:%S" )
==========================" | tee -a $LOG_FILE;
start at:?
You should just log command outputs to LOG_FILE ... not entire script.
And as always:
this code:
Code:
tune2fs -o journal_data_writeback /block/path/to/system;
tune2fs -O ^has_journal /block/path/to/system;
tune2fs -o journal_data_writeback /block/path/to/cache;
tune2fs -O ^has_journal /block/path/to/cache;
tune2fs -o journal_data_writeback /block/path/to/data;
tune2fs -O ^has_journal /block/path/to/data;
will never work.

^^^^ This ^^^^
We are here to further development. Keep the critical comments and insults out of here.
Be nice, work together to sort out issues, and try to get along for the good of all. Moderators do not ban those who are be respectful and trying to learn.
Final warning in here, be nice or get out.

Just to add, could somebody please tell me what this does?
Code:
##Syctl-Launcher
# grep sysctl /etc/init.d/*
/etc/init.d/02vm:# Load /sys/etc/sysctl.conf
/etc/init.d/02vm:sysctl -p
Because there is no 02vm script in init.d and these two lines doesn't seem to make sense to me.

I just pointed not working commands. Thats all.
I asure you (all of you) that those commands about tune2fs are copy&pasted from other so called "performance" mods.
Everyone is just copying same mistakes here on XDA, and none from so called "devs" actually are testing their mods.
You don't have to be a developer or programmer to see that this:
Code:
tune2fs -o journal_data_writeback /block/path/to/system
mod edit...why are we ignoring mod warnings? Better ways to reply with respect

I wont respond untill u stop Repeting This

Of not working command? lol
Why don't you try to run this command from adb shell from YOUR phone?
See what will happen.

This clearly prooved my comment.
@myaservip:
Do you know why this has errors?
Code:
tune2fs: No such file or directory while trying to open /block/path/to/system
Couldn't find valid filesystem superblock.
Also about not working half of the script. As I said you didnt close echo commands by ".
