Hello everybody,
I'm running Cyanogen 5.0.6-N1 on HTC Nexus One.
Recently I ran a sshd on it (following hxxp://wiki.cyanogenmod.com/index.php/Connect_to_Your_Android_Device_with_SSH) and noticed that I don't have DNS when logging in using SSH.
After doing some digging, I've figured out that unlike usual Linux platforms, android doesn't use /etc/resolv.conf (which resides on the read-only /system partition).
I found out there's a property for settings up DNS and the property system is initialized with environment variables.
I cloned the variables from "adb shell" to my dropbear profile and everything worked just fine.
For some reason, it doesn't work anymore.
Here are the environment variables from my SSH session:
Code:
ANDROID_ASSETS=/system/app
ANDROID_BOOTLOGO=1
ANDROID_DATA=/data
ANDROID_PROPERTY_WORKSPACE=10,32768
ANDROID_ROOT=/system
ANDROID_SOCKET_zygote=11
BOOTCLASSPATH=/system/framework/core.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/android.policy.jar:/system/framework/services.jar
ENV=/sd-ext/.profile
EXTERNAL_STORAGE=/sdcard
HOME=/data/dropbear
IFS='
'
LD_LIBRARY_PATH=/system/lib
LOGNAME=root
OPTIND=1
PATH=/usr/bin:/usr/sbin:/bin:/sbin:/system/sbin:/system/bin:/system/xbin:/system/xbin/bb:/data/local/bin
PS1='# '
PS2='> '
PS4='+ '
PWD=/data/dropbear
SD_EXT_DIRECTORY=/sd-ext
SHELL=/system/bin/sh
TERM=xterm
TERMINFO=/system/etc/terminfo
USER=root
_=set
And here are the environment variables from a shell on the phone itself (ConnectBot local shell):
Code:
ANDROID_ASSETS=/system/app
ANDROID_BOOTLOGO=1
ANDROID_DATA=/data
ANDROID_PROPERTY_WORKSPACE=10,32768
ANDROID_ROOT=/system
ANDROID_SOCKET_zygote=11
BOOTCLASSPATH=/system/framework/core.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/android.policy.jar:/system/framework/services.jar
EXTERNAL_STORAGE=/sdcard
IFS='
'
LD_LIBRARY_PATH=/system/lib
OPTIND=1
PATH=/usr/bin:/usr/sbin:/bin:/sbin:/system/sbin:/system/bin:/system/xbin:/system/xbin/bb:/data/local/bin
PS1='# '
PS2='> '
PS4='+ '
PWD=/
SD_EXT_DIRECTORY=/sd-ext
TERMINFO=/system/etc/terminfo
_=set
For some reason, the SSH session has no props set.
Code:
# getprop
#
Any clue what happens here?
Thanks,
Omri.
Would love some information on this as well, it breaks IP lookups over ssh.
I'm not sure when 5.0.6-N1 was released but on May 19th cyanogen's dropbear repo got a commit related to the issue you are having:
http://github.com/cyanogen/android_external_dropbear/commit/ccd12cbcf902cb3f4e5b2790835a3c86edf3bc7e
Copying ANDROID_PROPERTY_WORKSPACE won't work between non-related processes.
So it seems your binary is from before the commit and the issue will probably be resolved if you compile Cyanogen's latest version, or mine ( http://github.com/barryk/android_external_dropbear ).
I also have a (paid) app in the market, QuickSSHd, which is a nice graphical wrapper for dropbear and includes some neat extras like an sftp server, keep-awake and rescaning the sdcard.
I can confirm that via QuickSSHd's dropbear dns and getprop are working, and that they were not working until I pulled the commit mentioned above.
Thanks for the reply!
Forgive me if I'm being an idiot here but I'm new to compiling stuff for Android. I've pulled git, it gets quite a way into the compile then dies with:
Code:

Am I doing something obviously stupid or have I found a bug?
How are you compiling it? Using "mm"?
I wrote a little about compiling it here: http://teslacoilsw.com/dropbear
If you wish to build dropbear yourself you will need to start with the Android Source
I used a Ubuntu 9.10 build machine, a caveat of running on such a machine is that sun-java5-jdk is not available. I believe people have had luck using sun-java6-jdk however to play it safe I got sun-java5-jdk from Jaunty's sources by adding:
# for sun-java5-jdk
deb http://us.archive.ubuntu.com/ubuntu/ jaunty multiverse
deb http://us.archive.ubuntu.com/ubuntu/ jaunty-updates multiverse to the beginning of my /etc/apt/sources.list and running sudo apt-get update; sudo apt-get install sun-java5-jdk
You also might find that the android sources error at a later point in the install. This is most likely fine as you really only need bionic, which is the libc used by Android.
Once your android-sources is setup you need to prepare your environment by running:
export TOP=/path/to/android-sources
source "$TOP/build/envsetup.sh"
This will add a few shell functions to help building Android code. Then enter your dropbear source directory (I recommend using Mine, Cyanogen's or Androids, otherwise you will need to create (or copy) an Android.mk makefile.)
To build simply run:
mm
The binaries will be places in $TOP/out/target/product/generic/, in this case the SSH Daemon is at $TOP/out/target/product/generic/system/xbin/dropbear

But if you got a ways into it you might already be doing that.
Anyone have a working link for android-sources?
I have the ndk but I don't know if that's the same thing.
Ok, android sources built successfully, no errors.
Followed the instructions at the URL provided above.

Did I miss something in the build environment? The Android.mk being used is the one that's inside the git repo.
Weird, looks like it's not linking correctly. ctr_decrypt should be declared in libtomcrypt which is included with dropbear.
Were there any earlier build errors?

Only some warnings/notes, no errors.
Ok, I recreated the git repo and logged the entire build process.
Log attached.
EDIT: LOL! I just noticed it built. Maybe git got fixed, who knows. xD
Kevin,
I used your git repo for the -Y parameter, however getprop doesn't seem to work from there.
Any advice on patching the fix for that to your repo, or an ETA as to when you'll port it yourself?
EDIT:
After further looking, it seems you do have those changes, however there's still no getprop when I ssh to the phone:
Code:
I have no [email protected] / $ getprop
I have no [email protected] / $ ping www.google.com
ping: unknown host www.google.com
I have no [email protected] / $ dropbear -h
Dropbear sshd v0.52
Usage: dropbear [options]
Options are:
-b bannerfile Display the contents of bannerfile before user login

(default: /data/dropbear/dropbear_dss_host_key)
-r rsakeyfile Use rsakeyfile for the rsa host key
(default: /data/dropbear/dropbear_rsa_host_key)
-F Don't fork into background

EDIT 2:
Ok my getprop was being blown away by using a ported version of bash instead of sh.
Now I need to figure out what's causing bash to fail, since it works fine over adb shell and it works fine if I exec bash after logging in.
I'm having the same problem. I built dropbear from the TeslaCoil sources, and that didn't help. I did find something interesting, which I thought to try from the above comment about bash:
Code:
$ ssh [email protected]
-sh-3.2# ping -c 4 google.com
ping: unknown host google.com
Now instead, it works if I do:
Code:
$ ssh -t [email protected] bash
bash-3.2# ping google.com
PING google.com (74.125.226.145) 56(84) bytes of data.
...
(I need the -t option to force a pty when specifying a command.)
With the second command, everything works as expected. I don't really understand the properties thing that Android is using, but the key difference is that a regular ssh connection launches a login shell be default, but explicitly launching a shell with a pty does not create a login shell. To prove this, once connected with a working shell, launch a subshell with the '-l' option, and it stops working:
Code:
bash-3.2# ping -c 1 google.com
PING google.com (74.125.226.147) 56(84) bytes of data.
64 bytes from 74.125.226.147: icmp_seq=1 ttl=55 time=17.1 ms
--- google.com ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 17.120/17.120/17.120/0.000 ms
bash-3.2# bash -l
bash-3.2# ping google.com
ping: unknown host google.com
bash-3.2#
So are login shells a problem in Android in general? I know Linux inside and out, but Android is a bit weird. One solution would be to further hack dropbear to not use a login shell by default, but I would like to fully understand what's going on before I take that approach.
I think I may have figured something out. Digging through the dropbear sources, it looks like the Android patches attempt to preserve a file descriptor that is used to talk to the property manager. Creating a login shell closes all file descriptors other than 0,1,2. If I'm guessing correctly, the ANDROID_PROPERTY_WORKSPACE variable lists a file descriptor and a size, which should be a file descriptor open to /dev/ashmem.
I think that this explains what is going wrong. Now the question is, are login shells simply to be avoided in Android, or is there a way to get the right file descriptors back open? (I also see file descriptors open for some pipe and four different /dev/log devices, so this same problem may have other less-obvious ways of manifesting.)
This has been quiet for a while. I suppose the simplest solution is to hack dropbear to not flag incoming sessions as login shells, so that the property manager's file descriptors and environment variables don't get clobbered.
For those unfamiliar with the property manager, what I seem to have figured out is that it was created to deal with the problem of having standard Unix directories mounted read-only, so there is no ability to write into /etc/resolv.conf, for example. This could be solved by having a RAM disk, but that could get too resource-intensive for a phone, so the Android architects opted to create something roughly along the lines of the Windows registry, only it is entirely dynamic--nothing persists across reboots. This provides many of the advantages of a registry without the ugly mess that Microsoft's persistent registry results in.
I was running DroidSSHd v.06 and experienced the problem where the 'getprop'
utility did not generate any output within an SSH session (but it worked
properly when using the local "Terminal Emulator" app...
I installed QuickSSHd and this fixed getprop for me (Thanks Kevin!)...
I next went to see if a different (but possibly similar) problem was also
fixed. Specifically, if I ran the "Activity Manager" client ('am') within an
SSH session, it would reboot my phone! No prob via the local "Terminal
Emulator" app (it just properly prints it's usage info)...
Well, with QuickSSHd (v.2.0.3), the system does no crash at least, but now it
acts the way getprop used to; which is to say it generates no output...
The "Package Manager" client utility ('pm') is the same way (no output)...
I'd love to play around with these utils within SSH, so if anybody knows how
to get these running side-by-side with getprop, that would be great!
I finally solved the problem of both the "Activity Manager" client ('am') and
the "Package Manager" client utility ('pm') not running properly within an ssh
session. So I'll answer my own question here...
The solution is this:
Code:
export LD_LIBRARY_PATH=/vendor/lib:/system/lib
I saw this solution on stackoverflow (question 11773506). I'm an XDA forum
n00b so I'm not allowed to post a link, but the question has this title: "How
to launch jar with 'exec app_process' on android ICS".
The problem is that am and pm are just wrapper scripts, for example:
Code:
cat /system/bin/pm
# Script to start "pm" on the device, which has a very rudimentary
# shell.
#
base=/system
export CLASSPATH=$base/framework/pm.jar
exec app_process $base/bin com.android.commands.pm.Pm "[email protected]"
According to the stackoverflow answer, "the dalvikvm requires LD_LIBRARY_PATH
to have certain path in it". This solution worked for me. I just added the
"export" line to my shell's startup file (~/.bashrc)...
WARNING: THIS IS NOT FOR THE FAINT OF HEART
UPDATE: My goal was to create a version of BackTrack 5 for ARM that was easy to use and install. As of this time, that IS NOT the case! The versions posted here are **probably not** going to work straight out of the box. If you know what you are doing in a Linux environment, you'll probably be able to get it working.
Because of this, the project is currently completely unsupported. You are free to dive in, but you are doing so with no support for me, and I'm not liable for any damage that might be done to your device's ROM.
I encourage you to pass this up unless you know what you are getting yourself into!
If you were referred here from the XDA-Developers.com article...
Hi there! Let's get one thing on the record here... this is *not* a native client! This is the chroot + VNC method that we'd been using to get Ubuntu running with Android for a while. The article makes it sound like that's the case, but sadly it's not. However, with the chroot + VNC method we can really run BackTrack 5 on an Android device, and it really does work. This takes some technical skills, and isn't for the non-Linux experienced user.
Requires a rooted device!
BackTrack 5 installation guides are making their way around this forum. I've tried to synthesize it all, but I've also added my own touches to help with usability and features, along with a workaround for the "ioctl LOOP_SET_FD failed" error message some people have been getting.
In theory this build is nearly universal, so if you have an Android device it should work. I've put it all in one zip file that you can download directly from my website, no hassles or wait timers.
If you are interested have a look, feel free to re-post. Credit goes to the BackTrack team and xda member anantshri (he's got skills, give him props guys), who built the base image file.

BackTrack is an operating system based on Ubuntu Linux that is used for security testing (aka hacking) and digital forensics. I'm a master's degree student in computer security, so I love this OS... it can do awesome things. Turn on your Wi-Fi and you can do advanced network scans and tests right from your phone, no laptop required. For me this is hella-useful.
But besides just being an OS for hacking ****, it's also fully Ubuntu-based, so you can run it like a desktop, including running Firefox and other Linux applications.

The Download
This installation of BackTrack 5 is available as a compressed file that will need to be extracted. I recommend downloading this using Chrome or Firefox. Internet Explorer often doesn’t play well with large HTTP downloads.
The root account’s password and the VNC server password are both set to ‘root’ by default!

The Description
If you want to run BackTrack 5 on your Android-powered device, read on, you’re in the right place! So the big news is that BackTrack 5 runs on Android phones. We’ve been able to run Ubuntu on these devices for quite some time too, but admittedly BackTrack on a smartphone is just awesome.
Anyway, files for using BackTrack 5 on an Android phone have been running around the internet, but sadly it’s kind of a mish-mash of links saying, “go download this, then get this, to then this, blah blah blah”. Too confusing for my simple brain, so I’ve rounded it all up and posted it in one place… right here. The version posted here has everything you should need to run BackTrack 5 on your Android device. I’ve also added a lot of goodies to help with the user experience that the other offerings don’t include:
Works around the ioctl LOOP_SET_FD failed error that many people have been receiving on Galaxy S devices (and others)
Asks the user if they want a VNC session upon start-up
Starts the SSH service automatically and displays device IP on start-up
Enables the Ubuntu repositories to Aptitude, so you can do package installation
Adds vim. Really, what distribution doesn’t come with vim by default? Seriously…
Sets the screen resolution to 800×480 default (should be compatible with most smartphone devices)
SU
This requires root!
You must be able to "su" at terminal. This ability is usually provided by software for rooting your phone. To see if you have rooted your phone correctly and it's working, go to your terminal emulator and type "su" <enter>. If it is working, you'll probably get a prompt asking you if you want to allow your terminal emulator root access. Hit accept/yes. Now you'll be back in your terminal emulator. Type "whoami" <enter>. If it responds with "root" or "uid 0", then you are properly rooted.
Busybox
This requires Busybox!
I am no longer providing an installer for Busybox because of issues getting it to work universally, so instead YOU need to go get a working build and install it (I believe "Busybox Installer" will work, but not tested). If you want to know if you have Busybox and it's working, go to your terminal emulator and type "su" <enter>, then "busybox ls" <enter>. If you get a printout of all the files in your current directory, then your Busybox will likely work with BackTrack 5 just fine. If you get an error, "busybox: not found", that means you either do not have Busybox, or it is not properly installed.
WARNING FOR CyanogenMod USERS
Before doing ANYTHING, please test for ext2 support by running (as root, at terminal) --> "modprobe ext2" <enter>
If this fails probably your device lacks ext2 support and the whole thing will screw up if you try to run it! Support for ext2 in CM is being worked on.
The Installation Guide
Enable Wi-Fi and connect to a Wi-Fi access point (* not required, but BT5 cannot use your data plan for internet access)
Download the zip file, extract anywhere
After extraction you’ll have one folder “bt5″; copy this folder to the root of your phone’s SD Card
Put card back in phone and/or unplug from USB
In a terminal emulator, type “su” <enter>, “cd /sdcard/bt5″ <enter>
Now you are ready to rock and roll, so issue “sh bt” <enter> (in the future to start BT5 skip the line above and come straight to this command)
If all is well you’ll now be running BackTrack 5 on your Android device; you can SSH to it via Wi-Fi (password ‘root’), or access it from VNC if you said “Yes” to the prompt asking if you wanted a VNC session
To get a GUI for BackTrack on your smartphone’s screen, download a VNC viewer from the market (many are free), then connect to host “127.0.0.1″, port “5901″, password “root”
Enjoy, boys and girls.

Same error here, Verizon Fascinate.
Motodoido, tripacer99: have you remembered to do the "sh installbusybox" command first?
I download the new package, and this what i got:

Hrm yet another small error in one of the scripts. So sorry :S (this script is from the BT5 team though, so I take no fault in it not working, lol).
Open "installbusybox" in a text editor and replace the text "cat /sdcard/busybox" with "cat /sdcard/bt5/busybox" it should work. I'll fix it and put it up online once I'm home from work today.

I'll have to play when I get home... at the moment I don't have an answer :-/
Link is offline....
Hi,
I want to learn some of the commands for use in SManager (Script Manager) for ANDROID.
https://sites.google.com/site/devwom/script-manager
Does anyone know a suitable thread with guide or commands for SManager? I tried searching the web and XDA but did not find anything myself.
Specifically I want to know the cmd line to start an app.
EDIT 1:
Spent a good few hours trying to google a solution but drawn a blank.......Maybe Shell Scripts for Linux are not same as for Android...?
I would like to be able to run a script that does the following:
Checks if a directory exists on the sdcard
then executes a command (renaming of 2 directories)
then starts a program
EDIT 2:
well a few emails with the author of SManager and I was able to write my first script to check if the app is running and then if not, to rename folders and start the other version of the app. (I have Navigon Europe as well as Navigon Australia and was looking for a solution to allow both to co exist on my One-X at the same time. As both apps share the same directory structure the issue was that starting one version would overwrite the critical files of the other).
Now with my script installed as a widget I can toggle between each version without problem.
Here is some useful information on shell language for others (credits to the author of SManager Devwom):
http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html
Here are some critical bits of info received during my emails with him:
Thanks a lot for your interest in SManager.
The requested commands is a mix between linux commands and android os commands.
To get info about each command you can search in google and select the preferred page.
But the commands available in each Android device depends on running rom.
To get all available commands in your device, simply execute a ls (lower case LS) in system directories, that is:
ls /system/bin
ls /system/sbin
ls /system/xbin
ls /system/usr/bin
ls /system/usr/sbin
ls /system/usr/xbin
These are the most common directories where binaries resides in android devices.
May be you also can have commands at:
ls /bin
ls /sbin
ls /usr/bin
ls /usr/sbin
usually android rooted roms have the well known busybox, to get a list all comands inside it simply execute
busybox
to get all installed packages (and running names) from your device you can execute:
pm list packages
to get info about running process
ps
or
ps aux
or
ps -aux
depending on ps version installed
If conditions are based on test bash command this command is a bit confused, because usually it is named as [, and other times it is built-in inside shell
read "test man page" to get a full list of test command flags.
To check if an app is running:
if [ -n "$(ps|grep os.tools.scriptmanager)" ] ; then
echo SManager is running
fi
To check if app is NOT running:
if [ -z "$(ps|grep os.tools.scriptmanager)" ] ; then
echo SManager is NOT running
fi
To check if a file exist:
if [ -e /sdcard/file ] ; then
echo /sdcard/file exists
fi
To check if a file exist and it is a directory:
if [ -d /sdcard/file ] ; then
echo /sdcard/file exists and is directory
fi
To rename a directory simply use mv command:
I hope you can build your script with this info.
Start app it is very easy but getting correct info to start app is a bit confused.
starting app uses "am command"
To get correct info to start app you should execute:
logcat |grep Starting
in a terminal on device
then go to launcher and launch desired app
then go back to the terminal and you will see a line with info about how to fill am command.
For example if you execute SManager
in
logcat|grep Starting
output you will see
I/ActivityManager(* 275): Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=os.tools.scriptmanager/.launcherActivity } from pid 377
so to start scriptmanager you need the following command
am start -a android.intent.action.MAIN -c android.intent.category.LAUNCHER -n os.tools.scriptmanager/.launcherActivity
I do not know how to stop apps from command line, I usually use killall command:
killall os.tools.scriptmanager
if you do not have killall command you can use grep and awk or cut commands
kill "$(ps|grep os.tools.scriptmanager|grep -v grep|awk '{print $2;}')"
or
kill "$(ps|grep os.tools.scriptmanager|grep -v grep|cut -f5 -d" ")"
may you need adjust -f5 flag
To execute script as shortcut install SMWidgets.
Scripts usually ends with last line , ie, not special action is required, it will exit with the last executed command return code
Also you can add
exit 0
or preferred exit value, but 0 usually means OK
To end script in the middle use
exit value
where value usually it is not 0
Also it is better use mv command instead rename command.
rename command it is not linux standard, but mv command is in all linux shells.
Android shell programing it is not equals to linux shell programming but this was one of my first scripting documents many years ago and it can be used as a guide. http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html
Best regards,
Devwom
Thanks, this is valuable information! It's a shame this thread didn't get more replies
I've been looking to change my wallpaper by script, but so far I haven't been succesful. With your guide, I guess I'm a step closer to my goals!
Hi.
Perhaps developer of smanager or any expert is reading...
I would like to write a script for 2 purposes. Both handle with samba share running on my ubuntu.
1st situation.: I would like to move my media, download and documents files from android to the desired folder on my Ubuntu, which is shared by samba in my LAN.
The goal is to start this script with just touching a widget.
2nd situation: I would like to copy files from my samba shared folder in ubuntu to a specific folder on sdcard in android. All files in folder on sdcard should be deleted before copying. Again just by touching a widget.
Shared folder on samba are with password and rw.
Till now I am doing it manually with esexplorer...
I would like to do it with script.
Sent from my Incredible S using xda app-developers app
http://forum.xda-developers.com/showthread.php?t=1819660 Followed instructions here, no joy. Log following.
Notes: It detects busybox is running and wants me to clean, I take option 2 as detailed in the instructions and it proceeds to run option one. When I hit the second step in the commands to run (./photon-torpedo.sh) it gives me this error:
Unfortunatly your going have to enter some shell commands here
Not to worry though it only five commands press enter after each one
1 -- Enter at the first $ cd /data/tmp
2 -- Enter at the second $ ./photon-torpedo.sh
3 -- Enter at the first # ./kill-su.sh
4 -- Enter at the second # exit
5 -- Enter at the next $ exit
Once you are done the script will finish up and reboot your phone.

-Fails to give root access while running the torpedo as far as I can tell.
(would post to the thread this pertains to but I do not have enough posts to do so apparently)
In addition: this was previously rooted on a older version of the firmware, which one I cannot remember. Current BusyBox is 1.17.1 su is running binary v3.0(11) permissions are -rwxr-xr-x rootshell /system/bin/su
From the terminal, I would like to learn how to open a file in an android app.
As an example, how would I open /storage/emulated/0/Download/test.txt in Ted lightweight text editor?
When I try this:
Code:
am start -a android.intent.action.EDIT -n fr.xgouchet.texteditor/.TedActivity -d /storage/emulated/0/Download/test.txt
I get an error that includes "Permission Denial: startActivity asks to run as user -2 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL"
I'm not sure exactly what that's about, so I try to work around it with this:
Code:
am start --user 0 -a android.intent.action.EDIT -n fr.xgouchet.texteditor/.TedActivity -d /storage/emulated/0/Download/test.txt
Now Ted editor starts, but it opens a new file and not the specified file. I tried multiple times; one time there was a message at the top saying something to the effect that the specified file could not be opened. I've also tried different test files to exclude the possibility that test.txt is corrupt.
I'm stuck. Please help!
P.S. Ted's AndroidManifest.xml is available on github. I tried posting the link but, being new to the forum, I was not permitted to do so.
------------------
OS: CM11
Device: Moto G
Relevant apps: Terminal Emulator (jackpal.androidterm 1.0.65), Ted (fr.xgouchet.texteditor 1.8.1)
1) After countless hours of trial and error, I figured it out. Entering this command in the terminal opens the file for editing in Ted:
Code:
su -c "am start -a android.intent.action.EDIT -n fr.xgouchet.texteditor/.TedActivity -d file:/storage/emulated/0/Download/test.txt"
If you are reading this thread and like to write your own shell scripts, these two commands might also come handy if your script uses both CLI and GUI utilities:
2) To see the name of the app currently in the foreground:
Code:
su -c "dumpsys window windows" | grep mCurrentFocus | cut -d'/' -f1 | cut -d' ' -f5
3) To put the terminal in the foreground again:
Code:
su -c "am start -n jackpal.androidterm/.Term"
If you know how to do 1) (see my previous post) without root privileges, please post it here.
It doesn't make sense to me that root privileges would be required to open a user-owned file in a text editor. Android is linux, after all, so I'm hoping that anything a normal user can do via the GUI can also be done from the command line.
