Image Crunch

A very simple Bash script that runs an Imagemagick command.

Operates recursively on files and subdirectories in the target directory.

Builds a target directory containing processed files, with the same directory structure as the original.

Uses Imagemagick.

Instructions

• Add this file to a directory in your shell(Bash) path
• Make it executable (sudo chmod +x /usr/local/bin/image-crunch)
• In your terminal, move into the images directory
• Enter image-crunch
• Select a width when prompted
• Select compression or not
• Select a name for the new directory

The script copies all files and subdirectories into the newly specified subdirectory.

It then applies an Imagemagick command to all files in this directory:

if [ true == $compression ]
then
  # Imagemagick command on all files, recursive, with compression
  find ./ -name "*.jpg" -exec mogrify -resize $image_width -density 72 -quality "70%" {} \;
else
  # Imagemagick command on all files, recursive, No compression
  find ./ -name "*.jpg" -exec mogrify -resize $image_width -density 72 {} \;
