Hi.
This is very simple.
Create an Image of the SD Card by using dd
dd if=/dev/sdx of=imagename.img bs=4M
Then run this script, voila !
#!/bin/bash
# Automatic Image file resizer
# Written by SirLagz
strImgFile=$1
if [[ ! $(whoami) =~ "root" ]]; then
echo ""
echo "**********************************"
echo "*** This should be run as root ***"
echo "**********************************"
echo ""
exit
fi
if [[ -z $1 ]]; then
echo "Usage: ./autosizer.sh <Image File>"
exit
fi
if [[ ! -e $1 || ! $(file $1) =~ "0xc" ]]; then
echo "Error : Not an image file, or file doesn't exist"
#exit
fi
