shell bash for android

[mzet]

hi,
i compiled bash and added support for executing file /sdcard/bash_profile, so you can set PATH and PS1 variables there, for example...

if someone is interested, there it is for download
http://pub.mzet.net/bash

for become default shell copy bash to /system/bin/bash a then run:

cd /system/bin
chmod 0755 bash
mv sh sh0
ln -s bash sh

NICE! Good job mzet. I missed bash and its wonderful auto complete. This should help spur better scripting with all the functionality that bash supports. No more semicolons at the end of each line in a shell script.

On a side note, we should be able to add the following to init.rc rather than symlinking sh -> bash

export SHELL /system/bin/bash

here is example of my /sdcard/bash_profile

PATH=/sbin:/system/xbin/bb:/system/xbin:/system/bin
if [[ ${EUID} == 0 ]] ; then
  PS1='\[\033[01;31m\]\h\[\033[01;34m\] \W \$\[\033[00m\] '
else
  PS1='\[\033[01;32m\]\h\[\033[01;34m\] \w \$\[\033[00m\] '
fi

it shows localhost in green color when user is logged or in red color when root is logged...

strange. is this variable used? when i execute "echo $SHELL" it writes "/bin/sh", but it does not exists, it should write /system/bin/sh, i think

"/bin/sh" is ok. It's in boot.img...(respectively in ramdisk). Check out some ramdisk

Ya I noticed that after posting my last message. Perhaps it's not used. I'll try and find some time to change that in init.rc and reboot to see if it takes effect

I tried adding that to my init.rc and not doing the symlink and lost my shell, which I expected. I figured a reboot would fix it, but got stuck @ boot image. No problem...recent nandroid.

EDIT: Using the symlink works fine for now. Thank you!

Very cool. Thanks for giving us bash for Andriod! While we're thinking of low level tools, anyone have a version of busybox with colorized 'ls'?

Anyone know when /system/sd is mounted in the cyano ROMs? If it's available early enough, we could copy bash to /system/sd and avoid taking up 2.5MB in /system/bin.

it's too big, because everything is built statically
