If a tag does NOT contain...?!

I'm trying to make a report of all TIFF files in a directory that do NOT have an alpha channel named "Transparency."

Code Select Expand

exiftool -fast2 -photoshop:alphachannelsnames -ext tif -if '(not $AlphaChannelsNames =~ /Transparency/)' ~/Desktop/test -csv > ~/Desktop/report.csv

Any help would help me get off the ledge.   : )

Aside from the fancy quotes, I don't see why this shouldn't work.  Use plain single quotes.

Here's the test folder used.  One has an alpha channel called "Transparency" and another does not.  I've attached the report that is issued.  Maybe it's because the one without 'Transparency' actually doesn't have the field at all?

No bueno.

I thing you are correct - the following should work:

Code Select Expand

exiftool -fast2 -photoshop:alphachannelsnames -ext tif -if '((not defined $AlphaChannelsNames) || (not $AlphaChannelsNames =~ /Transparency/))' ~/Desktop/test -csv > ~/Desktop/report.csv[\code]

And so it does!  Deep bow to the senseis!  - J
