Often you have to resize images from a camera for using them on a website or a gallery or if you want to send them via email.

With the following command you can easily resize images inside of a directory ( the „imagemagick“ package must be installed on your system ).

for i in *.jpg; do echo "$i"; convert "$i" -resize 25% "$i"; done

(in some shells you have to remove the “ form $i):

for i in *.jpg; do echo $i; convert $i -resize 25% $i; done

If you would like to store the resized images in a separate folder, you can use these two commands:

// create folder with name resized
mkdir resized

//resize images and store the in folder resized
for i in *.jpg; do echo $i; convert $i -resize 25% resized/$i; done

The „echo $i“ print out the files on the terminal.
