FYI: The ExifTool "<=" operator sets a tag value from the contents of a file, and "-" is the STDIN file.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Quote from: StarGeek on November 18, 2022, 11:01:00 AMI couldn't for the life of me find anything on the internet describing what '<=-' does in a unix command line piping / redirection context. Less than, hyphen, I get those, but equal sign?

See my link above.
* Did you read FAQ #3 and use the command listed there?
* Please use the Code button for exiftool code/output.
 
* Please include your OS, Exiftool version, and type of file you're processing (MP4, JPG, etc).
