I want to assign the photo's creation date to its modified date but when try this line

exiftool -ModifyDate=$CreateDate DSC_2808.jpg
I get this error

Invalid date/time (use YYYY:MM:DD HH:MM:SS[.SS][+/-HH:MM|Z]) in IFD0:ModifyDate (PrintConvInv)
So could somebody pass on the correct syntax?

Thanks!

Try:

Code:

exiftool -ModifyDate<CreateDate DSC_2808.jpg

Note the lack of a minus sign on the second tag. I overlooked that and pulled my hair out for ages!

Thanks Justin.  That will work, but you need quotes around the argument
containing a less-than symbol. (ie. "-ModifyDate<CreateDate"). - Phil
