So though of making a guide for it.
I personally use es file explorer as i find it easy..
For list of scripts check the second post
So open es file explorer
Touch option key right of home key.
Go to tools-> Root explorer -> Click on off button it will ask for permission allow it-> now again tap on root explore-> select mount R/W set it from RO to RW
Now copy the script by long pressing the script/file in the bottom you will see copy option tap on it now go to paste to system/etc/init.d/Here and paste it(You will see 3 options at the bottom Paste , New ,Cancel ).. Select paste..
After pasting select the file by long pressing on it-> Tap on more -> Select properties Go to permissions-> Tap on change -> Tick on all the check boxes all 9 not the bottom 3..
Reboot your device.. Vola!! Memory increased.. You can check in settings-> Apps
It will encourage me to make more helpful guides
