I want to write empty string to title tag, but not work.

Code Select Expand


exiftool -xmp:t* .\0011.jpg
Title                           : Room

exiftool -xmp:t*^= .\0011.jpg

exiftool -xmp:t* .\0011.jpg
# nothing

This works perfectly for me on MacOS with the latest version of ExifTool if I quote the arguments in your command.

What O/S and ExifTool version are you running?

If on Windows using CMD/batch file, it does need to be quoted because the caret ^ character is an escape character.  PowerShell doesn't need quoting.

You're really stressing ExifTool.  I've never tried this (and I never imagined that any sane person would).

You've found a bug in ExifTool that will be fixed in version 12.25.

Thanks for pointing this out.
