How to run BASH script in my Android?

Question

My same BASH script is working in Fedora/CentOS.

But I am testing one Android eee pad transformer.

Where i have terminal access and i wrote a small test script. But its not working, how can i fix it? what am i doing wrong?

/data/data/berserker.android.apps.sshdroid/home $ cat test.sh 
#!/bin/bash
var=`ifconfig -a`;
echo $var;

/data/data/berserker.android.apps.sshdroid/home $ chmod +x test.sh 
/data/data/berserker.android.apps.sshdroid/home $ ./test.sh 
sh: ./test.sh: not found
/data/data/berserker.android.apps.sshdroid/home $ uname -a
Linux localhost 2.6.36.3-00004-g069b8b5 #1 SMP PREEMPT Wed May 11 22:14:22 CST 2011 armv7l GNU/Linux

/data/data/berserker.android.apps.sshdroid/home $ bash ./test.sh 
sh: bash: Permission denied

/data/data/berserker.android.apps.sshdroid/home $ ls -l /bin/bash
ls: /bin/bash: No such file or directory

/data/data/berserker.android.apps.sshdroid/home $ find / -name "bash"
find: /config: Permission denied
lots more.......
find: /proc/595/task/598/fd: Permission denied
......
find: /data: Permission denied
find: /root: Permission denied

Follow up:

This is my script now which works:

#!/bin/sh
echo "hello wassup, run me simply as './test.sh'";

or

#!/bin/bash
echo "hello wassup, run me using 'sh ./test.sh'";

in Android the shell is located in /system/bin/sh not /bin/sh like it is on most Unix-like systems. So even if you change #!/bin/bash to #!/bin/sh it will still not work. you'll have to use #!/system/bin/sh

Android is not a GNU/Linux distribution so you can't expect that all scripts that run on GNU/Linux to also work on Android.
