[Bash] got bored? bash styles

i got bored looking at the standard # or $ in bash so modified my bashrc with something from bashstyle-ng.
does anyone else have a different bash? show it off!

replace /etc/bash/bashrc file with this one to get the same look
Code:
# /etc/bash/bashrc
#
# This file is sourced by all *interactive* bash shells on startup,
# including some apparently interactive shells such as scp and rcp
# that can't tolerate any output. So make sure this doesn't display
# anything or bad things will happen !
function pre_prompt {
newPWD="${PWD}"
user="whoami"
host=$(echo -n $HOSTNAME | sed -e "s/[\.].*//")
datenow=$(date "+%a, %d %b %y")
let promptsize=$(echo -n "+([email protected]$host ddd., DD mmm YY)(${PWD})+" \
| wc -c | tr -d " ")
let fillsize=${COLUMNS}-${promptsize}
fill=""
while [ "$fillsize" -gt "0" ]
do
fill="${fill}-"
let fillsize=${fillsize}-1
done
if [ "$fillsize" -lt "0" ]
then
let cutt=3-${fillsize}
newPWD="...$(echo -n $PWD | sed -e "s/\(^.\{$cutt\}\)\(.*\)/\2/")"
fi
}
# Test for an interactive shell. There is no need to set anything
# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.
if [[ $- != *i* ]] ; then
# Shell is non-interactive. Be done now!
return

Your prompt takes too much space, and it contains date + time, which are already shown on the screen (top and bottom).
Just make the prompt PS1='\e[34m\[email protected]\h:\w \$ \e[0m' so it's ready for cut&paste, e.g. when you're copying files with scp.

Tizen chrooted for Android

Hello xda-developers!
I'm trying to port Tizen for samsung wave 1.
But now I'm doing some research.
This thread will be my research on doing a chrooted scripts and try to boot a Tizen 2 Alpha working through vnc-viewer.
I'll write here my scripts for everyone to test it.
After these scripts an app. But now scripts.
This thread will be updated everytime I get a spare time to write it.
Thanks!
Tutorial:
First download the image from the torrent file.
Copy it for your extsd or sdcard phone/tablet.
It's to copy the image file from Tizen 2 Alpha for these two places.
And on terminal emulator run the tizen_run bash file.
Test it and I will test it too as I'm writing this tutorial and post.
Rename the script tizen_run.sh.txt to tizen_run.sh
Thanks !

what can we do with this file?

In badadroid vnc-viewer and terminal emulator You can run Tizen under android.

sorry for the noobs questions, but how??
Edit 1:
I saw your tutorial just now, but I did not understand what to do in the terminal emulator?

There's no problem at all.
You need to copy the code into a file bash(.sh) with the name tizen_run.sh
Then in badadroid run it an app called terminal emulator to get into vnc-viewer.
As a loopback image inside android.
I'm trying to run it as an application like linuxonandroid.

I think I am not smart enough to do understand you..
But thanks anyway..

Okay.
I'll upload here the file to run on terminal emulator.

I'm testing the app for android.
I'll upload it here.

Something wrong.There are no permission to tizen_run.sh
I can't test

New link for image tizen:
http://tizen-kernel-s8500.googlecode.com/files/tizen.7z.001

Try this command:
sh tizen_run.sh
or
./tizen_run.sh

Copied Tizen.img (latest one) to sd card
Copied tizen_run.sh to sd card
Then on Android (Nand Ver.) Emulator tried
sh tizen_run.sh ---> no such file or directory
./tizen_run.sh ---> not found

I'm going to check it out.
type this on terminal emulator:
cd /mnt/extsd - if exists
cd folder "where the Tizen.img and script is located"
then
sh tizen_run.sh
or
./tizen_run.sh

I'll post a new file.
To see what happens.

in the first topic i have a txt file rename it on linux.

news??

Sorry about not saying any news.
Next week another build and a better script with an app for badadroid.

[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?

Oh, thanks

Is compatible with custom kernel? Franco in my case
vía n7II r-paco

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.

Rooting the webOS TV

pivotce.com informs that instructions have been published on gaining root access to a webOS TV. This is much harder than on the old phones and tablets. When this was done on legacy webOS, there was a wave of enhancements and tweaks made available to phone users from webOS Internals and other developers.
The instructions can be found on the Russian webOS forums here: webos-forums.ru/topic4650.html (English Translation via Google).
As the thread itself notes, this creates the possibility of fiddling with your TV in a way that may turn it into a large, thin brick and will almost certainly invalidate your warranty. The general user should stay well clear of this.
pivotCE published this for information only and recommend leaving investigations to those who know what they are doing or who can afford to wreck expensive television sets. We will watch to see if anything interesting emerges from this development.

Detailed analysis of the root access method described above:

Hello!
I'm from webos-forums.ru. I've root on TV for a while and can help you with translation or testing on LG webOS 1.4.

I could use your help rooting my lg 65uf6450-ua if you would. Thank you

1. You need to install Developer Mode App and export private ssh-key with CLI (webostv.developer.lge.com/develop/app-test)
2. Convert private ssh-key with puttygen [import key <your private ssh-key>, then save private key]
3. Download exploit (zalil.su/6937580), then connect with TV User: prisoner, [<ip-tv>:9922] + private-key with WinSCP (or other SCP-client), upload to /media/developer on TV and rename it to root.
on linux
Code:
ssh -i <your private ssh-key> [email protected]<ip-tv> -p 9922 "/bin/sh -i"
4.
Code:
chmod +x root
Code:
./root
5. After try install any app from market go to LG App Store and try to install any app.
6. if third stage ok. the insert password 1111 as said.
7.
Code:
busybox chroot /proc/1/root
Code:
[email protected]tTV:/# id
Code:
uid=0(root) gid=0(root)........
I personally use Linux Subsystem on Windows 10 for all of this.
To install .ipk app:
Code:
ApplicationInstallerUtility -c install -p /tmp/<any-name>.ipk -u 0 -l /media/developer -d
Info about your linux kernel and TV firmware:
Code:
luna-send -n 1 -f luna://com.palm.systemservice/osInfo/query '{ "subscribe": false }'
Launch app:
Code:
luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix"}'
All apps ID you can find with
Code:
luna-send -n 1 "palm://com.palm.applicationManager/listLaunchPoints" "{}"
or at a folder /media/cryptofs/apps/usr/palm/applications/<App ID>/appinfo.json
For permanent root access through telnet:
1)
Code:
[email protected]:/# mkdir -p /media/cryptofs/root/etc
2)
Code:
[email protected]:/# cp -r /etc/* /media/cryptofs/root/etc
3)
Code:
[email protected]:/# mount -o bind /media/cryptofs/root/etc /etc
4)
Code:
[email protected]:/# passwd root
Enter any new root password
5)
Code:
cp /media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh /tmp/start-devmode.sh
6) Download with WinSCP start-devmode.sh and edit it locally.
You need to add at the beginning
Code:
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
Plus you can add the line to launch any App at start, e.g:
Code:
luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'
And comment Dev Mode online check.
Here it's mine start-devmode.sh. It's for webOS 1.4. It can be different for other webOS versions:
Code:
#!/bin/sh
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
#luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'

Ok, so I get run the root app and first ,second , and third stage all are good. then it says try get root password is 1111. But the terminal keeps freezing after that happens. A couple times my tv rebooted too. I cant figure out what i could have messed up. ANyone with any experience using this method have any legit information?

Try to delete all 'cache' files from exploit at /media/developer. It doesn't wotk twice as far as I concerned

Is there anyway I can root my 1.4.0 and if so what r the benefits of the root? Can I install Android or kodi? What's the point

I tried it stil seems to finish step 3 then says enter 1111. But this is where it freezes up and does not get any further.

Which TV and firmware version?
Is this possible with UJ63 serie?

Hi, would the root access allow somehow to connect other bluetooth devices different than LG? Thanks!

You can do pretty much anything to the system with root, even include support for unsupported devices in form of additional kernel modules.
For example, I've added Samba support so I can mount use my NAS (see my blog at ddscentral dot org for details).

Hey guys is it possible to install android apps into WebOS? I just bought an Lg oled LG 55EG9A7V i want to use Perfect Player IPTV but i cant install it right now...Other then that i dont need anything else..
Can anyone help me?

Can somebody help me with this shell script?
