I want to resize all 5th images(*-5.jpg) to the new folder. I've tried below command but no luck:

mogrify 
-path 
  public_html/images/thumbs/*-5.jpg 
-resize 16×12 
-quality 100 
  public_html/images/new-thumbs/*-5.jpg

Answer 1

"Mogrify" should be called from the directory with the original thumbnails, while the -path parameter is for pointing target directory.

mkdir public_html/images/new-thumbs
cd public_html/images/thumbs
magick mogrify -resize 16x12 -quality 100 -path ../new-thumbs *.jpg

The last arguments are the list of files, so you can filter by name 1-*.jpg for example.
