How to Copy "Title" tag to "Description" + add some custom text

[bartek]

Hi,
I've searched a lot for this but cannot find an answer that works so I really hope you can help.

I'm using exiftool to copy the "Title" tag of multiple .jpg files into the "Description" tag.
So I have this command that does the job:

Code Select Expand

exiftool "-Description<Title" *.jpg

Now I would like to add some custom text (for this example let's say "Created by Bartek in 2024") to the end of the Description.

so the tag Description would have the Title+Custom text at the end.

Is it possible to do withing one command ?

See this example command.

Try
exiftool "-Description<$Title Created by Bartek in 2024" file.jpg

Hi! Thanks for your reply. I'm getting this error with this command:

Code Select Expand

Warning: No writable tags set from aayz.jpg
Warning: Invalid tag name 'created by bartek in 2024'. Use '=' not '<' to assign a tag value - aayz.jpg
and when I use = instead of <, than I just get the "Created by Bartek in 2024" without the title in front.

On Mac/Linux, use single quotes around anything that includes a Dollar Sign because otherwise it is considered a shell variable instead of part of the exiftool command.

On Windows PowerShell, you can try single quotes, but no guarantee, as PS quoting rules are different. The above command will work in CMD.

thank you. On windows 11 changing from " to ' did the job.
So:

Code Select Expand

exiftool '-Description<$Title. Created by Bartek in 2024' *.jpg
works perfectly as I wanted. Thank you for your help
