I am using exiftool from the DOS-box, and am frequently extracting sub-sets of the tags on collections of .jpg files using the -T option
Many of these tags are only set on some of the files. How, from the command line, and I make the output of missing tags simply be to adjacent tabs? I.e, how do I make missing tags distinguishable form tags with a value of - (hyphen character)?
To do this, add this option to your command: -api missingtagvalue=""
This is mentioned in the description of -f in the application documentation.

Thank you. I mistakenly thought that "API" referred to calls to exiftool from other programs, not to the command line as well. Hence I skipped over that section. I apologize for my misunderstanding.
Ah. The API is the Image::ExifTool Perl library interface (https://exiftool.org/ExifTool.html). There are lots of lower-level options there that are only exposed on the command line via the -api option.
