Bash script to resize images

To make sure that this script works correctly, check that ImageMagic pack is installed on your Linux machine.

#! /bin/bash

dir=$1
target_dir=$2

mkdir -p $target_dir

list=`ls -1 $1`
for i in $list
do
        echo $i
        convert $dir/$i -resize 50% $target_dir/$i
done

Usage:

./convert_50.sh Pictures/temp/ Pictures/temp_new

This will resize all images in location Pictures/temp/ for 50% and will copy them to new location Pictures/temp_new
