[GUIDE] Full bash shell with nano, tab completion, and color over ssh and adb

[jmxp69]

Posting this here because I think it will be of more interest to the tinkerers/devs than general users, if not, feel free to move it. I cobbled all of this together from various places on the web, but I think the credit for the binaries goes to Paul @ MoDaCo.

Nandroid before going any further!

Files you'll need:

For WiFi and CDMA SSH access - QuickSSHD (Download this from the Market. $1.50). I'm just going to assume if you're still reading, you know what this is for and how to use it. It's braindead simple. I think dropbear can be installed and configured manually, but for the $1.50...meh.

adb for tethered access.

The rest are zipped up here: terminfo, nano, bash, profile**

Unzip bashnano.zip onto your SDCard.
adb remount

From adb shell:

Install Terminfo:
cp -r /sdcard/terminfo /system/etc

Setup Bash:
cp /sdcard/bash /system/bin/bash_new
mv /system/bin/sh /system/bin/sh.old
ln -s /system/bin/bash_new /system/bin/sh
mv /sdcard/profile /sdcard/bash_profile (Thanks to jjvcuyler for finding adb bash profile location.)

Setup Nano:
cp /sdcard/nano /system/bin


I'm not sure if this setup will have any impact on sh scripts being used in the various ROMs, so use this at your own risk. I think it would kick ass to see this type of bash functionality baked into the custom ROMs.

If anybody would like to make this a flashable.zip, please do. I don't know how to do that yet.

Anyway, hope y'all find it useful.


**profile reflects a few personal choices for aliases and colors, but you can edit to your personal taste.

So I just did this. Is there any way to get this functionality into a local terminal?

Also I was able to do everything from a local terminal without adb. Just do the following first:

su
remount rw

adb shell fires off bash, but it doesn't read profile from /etc. It's going to be a simple matter of figuring out where bash is looking for it. I just haven't found that out yet.

How do you like having full bash capabilities on EVO? Arrows/tab completion/color prompts, etc...

Copy profile to /sdcard/bash_profile

 

[jmxp69]

Copy profile to /sdcard/bash_profile

WooT! There it is. I'll update the OP. Thanks jjvcuyler.

Edit: /sdcard/bash_profile works for ssh and adb. OP updated to reflect the change.

there is no terminfo.zip and there is nothing in terminfo directory from within the original zip... help?

 

[jmxp69]

Sorry, I missed the recurse flag zipping the terminfo directory. It's fixed now. Go ahead and re-download.

Here's a link for just terminfo.zip

I modified the bash_profile to get rid of the colors since the window's cmd.exe doesnt support ansi colors. probably a better way to do this but it works for me.

also found this useful for setting PS1 to my liking http://www.cyberciti.biz/tips/howto-linux-unix-bash-shell-setup-prompt.html

is there a way to get tab completion through adb shell?

 

[jmxp69]

Yes. This works with adb shell. Just follow the directions in the OP.

Yes. This works with adb shell. Just follow the directions in the OP.

i have and i do have everything done as stated in the OP, when i try tab completion via adb shell (phone tethered with usb) from my pc, it just puts in a tab, it doesn't complete.

 

[jmxp69]

Hmm....could be a dos thing with cmd.exe. I haven't tried on a PC, I'm on a Mac. adb shell via OSX works fine with tab completion. Try ssh'ing in instead with something like putty? Once you get ssh going, you don't need a cable.

Edit: Confirmed...tab completion doesn't work over Win cmd.exe and adb shell.

Thanks for looking into it... I'll try getting it to work via linux instead. I guess ssh would be a solution, but i never turn wifi on.

Is anyone able to do a NAND backup/restore after doing this? With Amon Ra's recovery I was unable to NAND backup.

EDIT:
I think this is a big negatory. I was just able to do a NAND backup, so maybe the error I got was a coincidence after applying these changes.

 

[Vinny75]

Anyone else noticing that the time is always displayed as GMT in the prompt? The date command gives the correct time for my timezone but the bash prompt always shows GMT

Change PS1 line: \A to `date +%H:%M`

I followed the steps exactly, but end up with "- exec '/system/bin/sh' failed: Permission denied (13) -" while typing "adb shell" in a windows or linux terminal. I cannot recover the original sh because the root is lost, and I cant root my phone anymore probably because something wrong with the new sh. Any idea how to fix this?

EDIT: Acutally nevermind. adb shell works in recovery mode. but still, not sure why the modified sh doest work for me

The Downloadlink is dead!
So the thread is useless.

Yeah.....no.

A simple google search would have shown you that the files are here: http://66.197.42.222/bashnano.zip
or here http://androidforums.com/attachment...ide-installing-bash-nano-android-bashnano.zip.

EDIT: I've also attached it in case the links above ever die, there will still be one which does not.

ya this is great and all but any decent busybox installer will setup bash for you.
