How machine detects corrupted image automatically??

When I wanted to identify corrupted image, the program ends with the last messages
identify: Premature end of JPEG file 'corrupt.jpg'.
identify: Corrupt JPEG data: premature end of data segment 'corrupt.jpg'.
where corrupt.jpg is name of the image I used.As I think, this gives the image is corrupted to the viewer.But now I wanted the machine to detect the corrupted image automatically as soon as the image is downloaded(e-mail attachments). What should I do? Is there any commands so that the machine detects the corrupted image? Please help!!
With Regards

Run identify on the downloaded image, junk its output and look at the commands return status.

Thanks for your reply.
I issued the command as follows:
Code: Select all
identify -verbose corrupt.jpg >log.txt 2>&1
and I got the log.txt file. But I don't see any STATUS there. I am sure that corrupt.jpg file is a corrupted file. How and where can I check that status? What status I need to check ? Eagerly waiting for your reply!!

Type
after you run the identify command. A status of 1 means the image is corrupt.

Thank U once more for your quick response.
I tried but didn't get any status. The following is what I got.
/************************************************/
server:/home/proj/images # identify corrupt.jpg
identify: Corrupt JPEG data: premature end of data segment `corrupt.jpg'.
corrupt.jpg JPEG 406x491 DirectClass 67kb 0.010u 0:01
server:/home/proj/images # echo $status
server:/home/proj/images #
/***************************************************/
Actually we have Suse installed in out server and I am using SSH Tectia Client.
Thank you.
With regards,
Prakash Rai.

What shell. if you are using bash use $? instead of $status
check you shell manual.

Use this command (requires a modern version of ImageMagick):
- identify -regard-warnings 551933corrupt.jpg

With ImageMagick 6.6 only detect a corrupted image with the -verbose option.
