[SOLVED] Error for convert command in command line

Issue

I have a bash shell script as below.

#!/bin/bash

SIZES=("512" "1024" "2048")

for i in ${!SIZES[*]}
do
    SIZE=${SIZES[$i]}
    echo $SIZE

    # first, resize original image
    convert -resize $SIZE"x"$SIZE! chernarus2048.jpg chernarus$SIZE"x"$SIZE.jpg
    mkdir tiles$SIZE
    # slice resized image into 256x256 tiles
    convert -crop 256x256 chernarus$SIZE"x"$SIZE.jpg tiles$SIZE/tile%04d.jpg
    rm chernarus$SIZE"x"$SIZE.jpg
done

But when I run this in command line using the following command

sh generate_tiles.sh chernarus2048.jpg

I'm getting an error convert: command not found

I'm using OS X Yosemite 10.10.2.The image is kept in the same folder where the shell script is placed. Please help me out.
