Root trying to modify a scrjpt

[rhino889a]

Hey guys
Found a script called swapconf used for configuring swap fikes and partition
its written to be flashed for a different device.
I am trying to manually install it.
It uses Bash
I have found Bash compiled for android and put it in system/bin
Then put swapconf in system/xbin
Put the swapconf.sh in my initd
Set permissions and reboot

Ran swapconf in terminal

app_75@android:/ $ su
root@android:/ # swapconf
No SD Card found. Aborting.
/system/bin/swapconf: line 37: return: can only `return' from a function or sourced script
whoami: unknown uid 0
root permission required!
Exiting...
1|root@android:/ #
I am unsure of how to finish this project
Wondering if anybody here who understands coding woukd mind taking a few,minutes to look it over.
I included Bash as well

Start off with the command "su" then go from there. It might need different mount locations than the ones it has default. Look into that
