using -if with DateTimeOriginal to test for Null Data

Hi Phil, How do I write the ArgFile code to test if a date is NULL? I have had no success and I have tried every combination of possibilities. I even tried to use $Year (from Exitfool_config from before). -Brooks

-P -DateTimeOriginal<FileModifyDate -if $DateTimeOriginal eq " : : : :" # NOT $DateTimeOriginal # $DateTimeOriginal eq "" # $DateTimeOriginal eq 0 # $DateTimeOriginal eq "0000" Sample output F:\Photos\2005\2005_01_01>EXIFTOOL -ALLDATES *.jpg ======== IMG_0117.JPG Date/Time Original : : : : : Create Date : : : : : Modify Date : : : : :

Re: using -if with DateTimeOriginal to test for Null Data

Hi Brooks,

I'm not sure what you mean by NULL. Is the date an empty string, or all zeros, or missing entirely? How about this: Set the date/time only if it doesn't begin with a 1 or a 2:

-if "$dateTimeOriginal !~ /^[12]/"

Oh. But that didn't handle the case that the date/time is missing. Try this instead:

-if "not $dateTimeOriginal or $dateTimeOriginal !~ /^[12]/"

(you were close with "NOT $dateTimeOriginal", but the logical operators are all lower case in Perl.)

Re: using -if with DateTimeOriginal to test for Null Data

Hi Phil, I am not sure what I am doing wrong when trying to use @argile syntax. This is what I get.

#ArgFile DateTest.arg -DateTimeOriginal<FileModifyDate -if not $dateTimeOriginal or $date TimeOriginal !~ /^[12]/ # End of ArgFile DateTest.arg Results F:\Photos\2005\2005_01_01>exiftool -v -@ bv_UseModDate.arg IMG_0118.JPG Condition: syntax error - ~/^[12]/ -------- ~/^[12]/ (failed condition) Condition: syntax error - IMG_0118.JPG -------- IMG_0118.JPG (failed condition) 2 files failed condition

Re: using -if with DateTimeOriginal to test for Null Data

My mistake leaving an unwanted space in there. Here is the working argfile:

-P -DateTimeOriginal<FileModifyDate -if not $dateTimeOriginal or $dateTimeOriginal !~ /^[12]/
