Is there a way to modify the current caption?

Say I have a picture with caption "A", I want to change it to "A and B" without knowing A? The only way I know so far is
Code: Select all
old_caption=`identify -verbose file |grep caption|cut -c 14-`
then edit the old caption. Is there any better solution?

Do you mean comment in the Properties section? If so, you can use the %c string format at
http://www.imagemagick.org/script/escape.php
comment=`convert image -format "%c" info:`
to retrieve the comment and store it in a variable. Then change the variable to add more.

Although it's still an indirect solution, your command is more intuitive. Thank you.

If you do not care what was there already, you can just write over the old comment. Otherwise, I do not believe there is any more direct way to add to a comment. But the IM developers would have to comment to confirm that statement. Perhaps there is another way that I do not know about.

But I believe by modify, it really means replace and not add to.
