Installation of BusyBox on panda board on Android ICS kernel

Question

I am trying to install BusyBox on panda board which has an ICS Android kernel.

I used the steps below:

1. Download binary file which supports the panda board
2. Push it into /system/busybox folder
3. Install the BusyBox command line tools on the target by executing the following commands on booted filesystem:

   pc ./adb shell
   target$ cd /system/busybox
   target$ ./busybox --install .
   target$ ./sh  #here i am getting error like ./sh: precmd: not found

4. Save the original sh executable by renaming it, and then create a soft-link to BusyBox sh:

   target$ cd /system/bin
   target$ mv sh sh.android
   target$ ln -s /system/busybox/sh sh

5. Export

   export PATH=$PATH:/system/busybox:/sbin:/vendor/bin:/system/sbin:/system/bin:/system/xbin

Step 3 is to install BusyBox, and step 4 is to make BusyBox shell as default shell. But I am getting an error in the 3rd step. I want to make BusyBox shell as default shell, so I can run scripts on panda board.

I appreciate any type of suggestions or solutions. Thanks in advance.

If you are using Connectbot: according to an article at XDA-Developers, this is nothing but a cosmetical error:

Connectbot seems to set shell variable 'PS1' to "$(precmd)$USER@$HOSTNAME:${PWD:-?} $ ".
It means your shell (the busybox's ash applet) will try to use output from 'precmd' as a part of a command prompt. So when 'precmd' was not provided, error messages will be generated wenever a prompt was to be shown.

To fix this, mentioned post says you can use PS1="> " (or simply unset PS1) to work around that error.
