Is there a command to not include the tag names when writing to CSV? I recently realized that you can concatenate with >>, but would like to avoid having to always remove duplicate rows when doing this. Thanks so much.
No.
Here's a previous post (https://exiftool.org/forum/index.php?msg=76086) on the subject, though only the first half applies here.
Piping through tail would be the easiest. If you're on Windows, MSys2 (https://www.msys2.org/) is a port of Linux commands to Windows. Very useful as Linux commands are very powerful and there are a lot of examples on the web for using them.
There's also this post (https://exiftool.org/forum/index.php?msg=42604) which has a Window BAT solution using findstr.
