iinfo utility

Outputs information about an image.

Synopsis

iinfo [-i] [-s] imagefile [imagefile*]
where:

-i

Checks the image file’s integrity. If the file is corrupted in any way, the line: Integrity: File bad will appear in the output. Otherwise, Integrity: File OK will appear. If any of the read files read are bad, iinfo will exit with error status 1; if they are all good, it returns status 0.

-s

Suppresses output. When used in conjunction with the -i option, the exit status can be used in shell scripts to test the integrity of image files.
