Check the output before batch processing

[artyomtl]

It is now quite a while since I last used exiftool. I remember there was an option available to check the output of the command before actually processing files. I failed to find the option in the up-to-date documentation.

Is it still present?

If the feature was there then it still exists.

But I don't know what you mean by "check the output of the command", or "actually processing files".  Do you mean check the return status of the ExifTool command?  See the Exit Status section of the application documentation.  And "actually processing the files" how?  Using ExifTool?  In a separate command?

I mean simulation of actual processing. With that option I could see what would be the result of files renaming or moving without actually applying the changes

[Phil Harvey]

Oh, file renaming.  Write "TestName" instead of "FileName" for a dry run before renaming the files.
