Tasting the Ice Cream Sandwich

No, Android is different userland on top of the Linux kernel, instead of eglibc or µClibc userland. In this case, mksh’s got the ability to run directly using the Android bionic libc.

As for the .mkshrc file – it depends on which mksh you use. The one included in AOSP, Android-x86 and Google Android 3 and up looks for this file in /system/etc/mkshrc and standard mksh builds in ~/.mkshrc (but the location can be overridden by setting $ENV properly).

A suitable mkshrc file for Android follows:

tg@tglase-amd64:~ $ cat android/external/mksh/mkshrc
# Copyright (c) 2010, 2012
# Thorsten Glaser <t.glaser@tarent.de>
# This file is provided under the same terms as mksh.
#-
# Minimal /system/etc/mkshrc for Android

# Support: https://launchpad.net/mksh
