What Is ExifTool Command Line?

ExifTool is a powerful command-line tool for manipulating and extracting metadata from various file formats. When using ExifTool to write metadata, it's essential to understand how to correctly format your commands. In this article, we'll explore the importance of the -sep argument when writing subject tags.

When working with comma-separated keywords, it's crucial to enclose them in quotes to simplify the command. However, if you don't include the -sep argument, ExifTool may misinterpret the subject tag. This can lead to unexpected results, such as combining multiple keywords into a single 'keyword' including commas.

For example, let's consider the following command: `ExifTool -subject='mau égyptien,egyptian mau,chat,cat' _JNA0004.NEF`. Without specifying the -sep argument, ExifTool may read back the subject as `Subject : mau égyptien, egyptian mau, chat, cat`, which is not what you intended.

To avoid this issue, you can use the -sep argument to specify a separator between keywords. By default, if -sep is not specified, ExifTool assumes the default separator to be ','. However, in some cases, NeoFinder may misinterpret the subject tag, even with the correct formatting.

In conclusion, when working with ExifTool and writing subject tags, it's essential to use the -sep argument to ensure that your keywords are correctly interpreted. This can help prevent unexpected results and ensure that your metadata is accurately written to your files.
