Bash script to snatch all the covers for books in your Calibre Library and to move them to where you want them (optional resizing)
This will search your entire Calibre Library for your book covers and move them to a directory of your choice with an option to resize them to whatever size you like.
get_book_covers.sh **SourceDirectory** **OutputDirectory** -w **number** -h **number**
All arguments are optional. The defaults for the directory (both in and out) are the directory from which the script is run.
If -w and -h are not specified, no processing is done to the images. If either -w or -h is used, *both* must be used.
Output filenames are in the format of
**OutputDirectory**/Author Name_Book Name.jpg
Requires [ImageMagick](https://www.imagemagick.org/script/index.php) to resize images. If you're not resizing anything, you don't need it.
