Use the -format option to print properties associated with an image in a format of your choosing. You can include the image filename, type, width, height, Exif data, or other image attributes by embedding special format characters:
       %b   file size
       %c   comment
       %d   directory
       %e   filename extension
       %f   filename
       %g   page geometry
       %h   height
       %i   input filename
       %k   number of unique colors
       %l   label
       %m   magick
       %n   number of scenes
       %o   output filename
       %p   page number
       %q   quantum depth
       %r   image class and colorspace
       %s   scene number
       %t   top of filename
       %u   unique temporary filename
       %w   width
       %x   x resolution
       %y   y resolution
       %z   image depth
       %A   image alpha channel
       %C   image compression type
       %D   image dispose method
       %H   page height
       %W   page width
       %X   page x offset
       %Y   page y offset
       %Q   image compression quality
       %T   image delay
       %@   bounding box
       %#   signature
       %%   a percent sign
       \n   newline
       \r   carriage return
For example,
       identify -format "%m:%f %wx%h" bird.miff
displays `MIFF:bird.miff 512x480` for an image titled `bird.miff` and whose width is 512 and height is 480. Additional properties are recognized when enclosed in braces:
       %[base]
       %[channels]
       %[colorspace]
       %[depth]
       %[directory]
       %[extension]
       %[group]
       %[height]
       %[magick]
       %[max]
       %[mean]
       %[min]
       %[name]
       %[page]
       %[scene]
       %[scenes]
       %[size]
       %[standard-deviation]
       %[unique]
       %[width]
       %[xresolution]
       %[yresolution]
Or use `fx:` to evaluate FX expression:
       %[fx:expression]
Use `pixel:` to evaluate a pixel color as defined by the FX expression:
       %[pixel:expression]
You can also use the following special formatting syntax to print EXIF information contained in the file:
       %[EXIF:tag]
Where "tag" can be one of the following:
       *  (print all Exif tags, in keyword=data format)
       !  (print all Exif tags, in tag_number data format)
       #hhhh (print data for Exif tag #hhhh)

Surround the format specification with quotation marks to prevent your shell from misinterpreting any spaces and square brackets. You can also use the following special formatting syntax to print IPTC information contained in the file:
       %[IPTC:dataset:record]
Where dataset and record can be one of the following:
