Is there a way (I'm sure there is) to append text to an already exiting text tag like User Comment while leaving the original text behind.
There could be a simpler way, but this would work:
exiftool '-tag<${tag; $_ .= " add this text"}' FILE
Replace tag with the tag you want to append the text to and switch the single and double quotes when on Windows.
@Hayo: No need to use an advanced formatting expression. This is a bit simpler:
exiftool "-tag<${tag} add new text here" FILE

okay and if I wanted to add it to the beginning instead of the end I would do this ?
exiftool "-tag<add new text here ${tag}" FILE
Yup
