[Q] Run crond from init.d - Android Q&A, Help & Troubleshooting

Hi,
I have a Radxa Rock on which I am running Android 4.2.2, I am trying to get cron working to schedule some scripts to run.
I have got init.d working to launch a script at boot but I can't seem to be able to start crond from it. I have installed SSHDroid on the unit so I can putty to it, if I putty to the device and run
Code:
crond -b -c /data/crontab
cron starts and everything is running fine.
But when I add
Code:
crond -b -c /data/crontab
to my init.d script nothing happends and I can't seem to figure out why.
This is the full contents of my init.d script:
Code:
#!/system/bin/sh
# Init.d test
if [ -e /data/Test.log ]; then
rm /data/Test.log
fi
echo Init.d is indeed working !!! >> /data/Test.log
echo "excecuted on $(date +"%d-%m-%Y %r" )" >> /data/Test.log
crond -b -c /data/crontab
What am I doing wrong?

Can't say this is my forte, but maybe something from this thread can get you pointed in the right direction: http://forum.xda-developers.com/showthread.php?t=2090284

Thank you for your answer
I tried updating and using the full path to the crond but that wasn't working either. Then I realized that it wasn't working via putty either with full path. My conclusion was that I was using the wrong path, found out I could run "which crond" to find the correct path which was completely different. In my case "/data/data/berserker.android.apps.sshdroid/home/.bin/crond -b -c /data/crontab" was the full path and now it's working just fine.

Cool. Glad you're on the right track!

[Request] Dev Help Pretty Please!

Ok I'm on the OTA 2.3.4 from a fresh unlocked 4.1.83 no problems what soever and I'm looking to make a few mods when I saw the link posted for the 2.3.4 HDMI Mirror over at
http://forum.xda-developers.com/showthread.php?t=1169457
I went ahead and ran
adb shell
su
mount -o remount,rw /dev/block/mmcblk0p12 /system
sed -ie s/ro.hdmi.mirror.enable=false/ro.hdmi.mirror.enable=true/g /system/build.prop
mount -o remount,ro /dev/block/mmcblk0p12 /system
cd /etc/init.d
cp startXServer.sh startXServer.bak
(head -n 40 startXServer.bak; echo "if [ ! -e /var/run/noWebtop ]; then"; tail -n 12 startXServer.bak; echo "fi") > startXServer.sh
restart your phone
I read through the command and seemed pretty safe and was excited because the post listed the HDMI Mirror as being in "landscape" mode. Hell yeah right! Well it wasn't, it was the same portrait so I was looking to revert back. Go change the build.prop back for the ro.hdmi.mirror to equal false. No big deal that's easy enough with root explorer. Read through the commands and saw that the startXServer.sh was cp to startXServer.bak. Easy enough just delete the startXServer.sh and rename startXServer.bak to .sh.
Well there is the problem. When i ran the commands the first time didn't work so i went into the build.prop and did a manual change. Then re-ran the bottom half. It seems doing that I over wrote the .bak agan and now both files are exactly the same and have no way of reverting. I have the system, boot, and webtop backed up with an .img but that didn't fix my entertainment center when I plug in an HDMI to the TV. The original commands did a back-up so I didn't double back-up the file.lol
I was wondering if a dev that has a little more command line knowledge, maybe the orginal contents of startXServer.sh, or the actual file could help me out with the revert back and a working entertainment center. The current contents are
if [ ! -e /var/run/noWebtop ]
fi
I'm pretty sure that's the problem, unless someone else sees something I'm missing.
**Edit**
This was solved under the Q&A Section from a earlier post yesterday afternoon. Mods please close if necessary. In case any one needs it see below. I just rewrote the startXServer.sh to contain the following.
#!/bin/sh

[HOW TO] Install/Run Android SDK 64 Bit Native on Device

I learned about this here... http://fieldeffect.info/w/NativeCompileSDK
You can install an i386/x86_64 chroot within your existing Debian chroot using qemu-user-static to run the Android SDK on your Android phone/tablet/phablet.
1.
Get yourself a debian chroot, I recommend at least 2gb. I use DebianKit from market.
2.
You will need a X11 desktop environment and a VNC client on your device. I use androidVNC from market.
Here is my working example...
Start your Debian chroot/environment and do...
apt-get install openbox openbox-themes obmenu obconf menu menu-xdg xdg-utils xfonts-base xfonts-terminus* nautilus terminator lxappearance gmrun leafpad man-db hicolor-icon-theme tightvncserver tint2
That gives you a window manager, fonts, filebrowser, terminal emulator, text editor, theme manager, taskbar, and a VNC server.
Now lets get some GTK engines and libraries....
apt-get install gtk2-engines-auroa gtk2-engines-murrine gtk2-engines-oxygen gtk2-engines-pixbuf libgtk2.0-bin gtk3-engines-oxygen gtk3-engines-unico libgtk-3-bin
Now 7zip to handle zips and archives comfortably(put non-free in your apt sources.list)...
apt-get install p7zip p7zip-full p7zip-rar zip unzip
##The Android SDK manager, qemu, and multistrap##
apt-get install ant file openjdk-6-jre openjdk-6-jdk qemu-user-static libswt-gtk-3-java libswt-cairo-gtk-3-jni
3.
Now we can build a small x86_64 rootfs using multistrap
multistrap can use a config, have mine...
http://db.tt/hS5j3wg
Copy multistrap.conf straight into your working(pwd) directory....
cp /sdcard/Download/multistrap.conf .
Do this to avoid multistrap complaining later...
cat multistrap.conf >mstrap
mkdir /data/mnt
Determine size of rootfs for loop image..
du -hs /data/mnt/
Now make an image for x86_64 chroot
dd if=/dev/zero of=/sdcard/64bit.img bs=$(( 0x100000 )) count=YOUR IMAGE SIZE
That byte size makes your image slightly larger than the count value in Mb, for example count=78 will write 82Mb image.
mkfs.ext2 /sdcard/64bit.img
tune2fs -c0 /sdcard/64bit.img
mkdir /data/tmp
busybox mount -o loop /sdcard/64bit.img /data/tmp/
cp -r /data/mnt/* /data/tmp/
umount /data/tmp
rm -r /data/tmp/
rm -r /data/mnt/
mkdir /data/mnt
busybox mount -o loop /sdcard/64bit.img /data/mnt/
5.
Now the environment is set up and mounted, at this point install the SDK
Aim your browser to http://developer.android.com/sdk/index.html
Select "Linux" from "SDK Tools Only", thats the last thing at the bottom of the list.
cp /sdcard/Download/android-sdk_r21.0.1-linux.tgz .
7z x android-sdk_r21.0.1-linux.tgz russosv
7z x android-sdk_r21.0.1-linux.tar
Now we need a couple goodies from http://fieldeffect.info/w/NativeCompileAPK ##--Thanks to russosv from FeildEffect
These are edited from original....
#!/bin/bash
QEMU=/usr/bin/qemu-x86_64-static
64CHROOT=/data/mnt/
case "$1" in
mklinks)
if [ ! -e "./64BIT" ]; then
mkdir ./64BIT
fi
for i in $(file ./* | grep "ELF 32" | awk '{print $1}' | sed s/://g | sed s/[./]//g); do
echo "Moving $i..."
mv $i ./64BIT
ln -s ~/bin/run-64-link $i
done-
;;
*)
$QEMU $64CHROOT/lib64/ld-linux-x86_64.so.2 --library-path $64CHROOT/lib:$64CHROOT/usr/lib:$64CHROOT/usr/share/perl/5.12.4/unicore/lib:$64CHROOT/var/lib:$64CHROOT/lib/x86_64-linux-gnu:$64CHROOT/usr/lib/x86_64-linux-gnu [email protected]
;;
esac
Copy that to run-64, then...
chmod 755 run64
cp run-64 /usr/bin/
One more...
echo $(dirname $0)/64BIT/$(basename $0) [email protected]
/usr/bin/run-i386 $(dirname $0)/64BIT/$(basename $0) [email protected]
Make that run-64-link
chmod 755 run-64-link
cp run-64-link /usr/bin/
5b.
Now launch VNC server
tightvncpasswd
tightvncserver
killall Xtightvnc
cat >.vnc/xstartup<<EOF
tint2 &
terminator &
openbox-session
EOF
tightvncserver
export DISPLAY=:1
6.
Now launch the VNC client I mentioned earlier, should connect with 127.0.0.1:5901 and your password you set.
Go back to terminal or use the one launched on X11 to do...
sh android-sdk-linux/tools/android
Install at least one api.
If all went well you can now go around "debugging" yours and your friends Android devices over wifi now.
For an example, and to see it work do....
svc wifi disable(or enable) ##this turns off/on wifi
setprop service.adb.tcp.port 5555(or -1) ##this turns on/off adb over network
stop adbd
start adbd
adb connect 127.0.0.1(yours) or any other adbd addy listening on your network,
Have fun
Never did a "how to" before, go easy and I'll make corrections and answer things. Thanks for reading. Leave feedback.
Potential necro post but I believe the information is still currently valid and not readily available on searches. I've looked variations of this up for years with no luck until I hit the right search terms.
bump, and thanks.
can't believe there's no comments.
I know it's a slower than real-64-bit-pc method but not all of us have access to new hardware... or pc's. Maybe a novelty, still cool and useful if you've got the time to let the slower hardware compile.
you have preserved the scripts, original link is dead.
here is the Internet Wayback Machine cache of the original circa 2012 for reference.

[Q] adb works but not extract-files.sh

I am trying to extract vendor files from an i8730 phone using extract-files.sh
I have Linux Mint 14 with android-tools-adb installed as the adb
adb works fine to a point
[email protected] ~ $ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
333398202BDF00EC device
adb shell and ls shows files on the phone including the vendor folder
If I run ls from my working directly I can see extract-files.sh
Think the solution is in .bashrc but believe I am not doing it right. When I run extract-files.sh I get this
[email protected] ~ $ ./extract-files.sh
bash: ./extract-files.sh: Permission denied
[email protected] ~ $ sudo extract-files.sh
[sudo] password for megan:
sudo: extract-files.sh: command not found
[email protected] ~ $ sudo./extract-files.sh
bash: sudo./extract-files.sh: No such file or directory
location adb shows
/usr/share/doc/android-tools-adb
location bashrc shows
/etc/bash.bashrc
I have edit bashrc
[email protected] ~ $ sudo gedit /etc/bash.bashrc
[sudo] password for megan:
Have added this to the end
export PATH=${PATH}:/home/megan/usr/share/doc/android-tools-adb
Think this is where I have gone wrong. Any suggestions?
Thanks

Thanks MoonBlade. Think you are suggesting the version on the link so have been working through it. Had to source the files elsewhere as original link is dead. May or may not be a problem.
Got as far as creating the file in /etc/udev/rules.d/ but am unable to create a file in that folder. I am logged in as root. I can view the folder through GUI but not able to create 99-android.rules
Get this mess in terminal
[email protected] ~ $ su

Not sure the above is anything to do with not being able to write to that folder. Any ideas?

ok im not sure exactly what youre trying to do but it sounds like you want to get files from your phones /vendor/ directory and copy them to a directory on your computer. if this is correct then you need to stop playiing around with your .bashrc and your $PATH appends. all you need to use is adb
you dont have to adb shell. once you run adb shell it opens up a terminal inside your device so if youre trying to run a shell script on your computer from inside an adb shell it just wont work.
a simpler way to put this is, if you want to get /vendor/firmware/bcm4329.bin from your phone and put it on your computer in a folder on your desktop you would run it like this
$adb pull /vendor/firmware/bcm4329.bin /home/megan/Desktop/phonevendorfirmware/bcm439.bin
and the directory and file will automatically be created on your computer. from there you can do what ever you wanted to do to the files that you pulled from the phone.
the same works in reverse if you want to move a file to the phone using $adb push

You need to give execution permissions to the script, this way:
Code:
chmod +x extract-files.sh
And then, run your script like this (if the script doesn't need root permissions, run it without sudo):
Code:
sudo ./extract-files.sh
Many thanks haxin and RoberGalarga
I was given the extract-files.sh by a developer to extract vendor files for ROM development - i8730. He did not have the phone (I don't at the moment as has been wrapped for the kids to give to me for my birthday - practicing on an a Galaxy S)
From peeking inside the file it looks like a batch file that grabs all the content from the vendor folder. Did SQL 10 years ago and looks like that. Essentially does what you gave me haxim, but pulls the content of the entire folder. What is the best way to do that with adb pull?
Gave chmod +x extract-files.sh a try.
Without sudo I get
bash:./extract-files.sh : /bin/sh^M: bad interpreter: No such file or directory
With sudo
sudo: unable to execute ./extract-files.sh: No such file or directory.
Remember I am running this against a i9000, not the phone that I was given the sh file to run against. Get that back the begining of September. Not sure if that makes a difference but if it does not obvious to me.Seems to be falling over on the first line as that appears in the non sudo error message.
Have copied the content of extract-files.sh below.
Thanks again guys. Learning heaps and loving it.

is caused by a bad formatting in the file (Window$ editing... pfff....), so, make a new file using Gedit and paste this directly (don't copy&paste from the original script!!):

Delete the old file, and try the new one (you can use any filename, it doesn't matter).
Many thanks RoberGalarga.
Got the script off a recognised developer along with proprietary-files.txt and setup-makefiles.sh
He is working a CWM and a rom for owners of the i8730 - he does not have the phone so community feed in content. Get the impression he is not a Windows user (he did not have a Windows script for this) so reckon I might have corrupted it.
I did as you advised and made some real progress. Now we get the following:
[email protected] ~ $ sudo ./extract-files.sh
[sudo] password for megan:
egrep: ../express/proprietary-files.txt: No such file or directory
: not foundefiles.sh: 3: ./setup-makefiles.sh:
: Directory nonexistentk ./setup-makefiles.sh: cannot create ../../../vendor/samsung/express
[email protected] ~ $
It breaks further down the script. In the home folder there is proprietary-files.txt which list the files to be extracted along with their file path. Does that message indicate it is looking for proprietary-files.txt in /home/express?
Setup-makefiles.sh is in the home folder as well and appears to be a Cyanogenmod Project file to create a blob from the the results of extract-files.sh

Yes, that's it. Check again, seems like something is missing yet.
Thanks again. Got it to work by building the folder structure
/home/vendor/Samsung/express
And then running the files from there

[Q] autostart.sh and u2nl to init.d

How can I add u2nl to init.d? I have an HTC Evo 4g LTE and need to make android 4.3 Viper4g Rom run my script on boot. I've tried to use Root Explorer and Root Browser apps to manually add them to the init.d folder, set permissions and changed owner and group to root. But my phone won't boot after I've added my script. The name of my script file is autostart.sh and this is what it contains.
#!/system/bin/sh
export PATH="$PATH:/system/bin"
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -F
iptables -t nat -F
iptables -X

sh -c "sleep 5;kill `ps|grep nk.bla.android.autostart|grep -v grep|awk '{print $2}'`" &
exit 0
I know someone here has the knowledge to make this happen. Please advise and assist. Thanks. P.S. I have tried to rename the script to 99data and placed it init.d directory so it would run last but phone won't boot.?

have you tried a dummy test script that just echos a number to the sdcard file?
Thanks for replying. The script term-init.sh that I found elsewhere on XDA, had a test and set perms output file that can be found in /data/Test.log. I have solved the problem on my Evo 4g LTE but, not on my Sprint Galaxy S3. Turns out that I couldn't use Root Explorer to manually add the file! I had to REALLY MANUALLY add the file using the terminal emulator. That worked on the Evo but not the S3. I had placed the scripts in one postboot.rc files on S3 and it worked fine but, my battery seemed to be draining a lot faster, which was not acceptable. So I guess my problem is half solved. So, do you know how to make it work on the S3? Thanks in advance to anyone that can help me.

[Help] wget/curl Script worked prior to MM? now no longer works

I had a script that I ran via tasker when I was on 5.1.1 to download the pic of the day from Nasa
https://apod.nasa.gov/apod/astropix.html
Since upgrading to MM the script no longer works. It does work just fine via command line on linux machines(most likely d/t the increased support and ease of wget/curl) so I know the formatting is correct.
here's what I have
Code:
#!/bin/sh
wget -q -c -O ~/Downloads/potd/$(date +%m-%d-%Y.jpg) https://apod.nasa.gov/$(curl -silent https://apod.nasa.gov/apod/astropix.html > astropix.html && grep "IMG SRC" astropix.html | cut -c 10- | tr -d "\"") && rm astropix.html
On android I get as far as
Code:
sslv3 alert handshake failure
Any help would be greatly appreciated. I've tried setting different ssl/tls versions via curl and still nothing.
