Imagemagick Mogrify crop output name

Question

When using mogrify -crop 500x500 *.jpg

I get output as *-1.jpg, *-2.jpg, *-3.jpg, *-4.jpg

Is it possible to change so that it gets a different separator. eg. underscore?

output: *_1.jpg, *_2.jpg, *_3.jpg, *_4.jpg,

Answer 1

You can do this with convert:

convert *.jpg -crop 500x500 -set filename:f "%t_%p" '%[filename:f].jpg'
