copy the "Date Picture Taken" in "File Modification Date/Time"

[uppa]

I have a lot of jpg files that I have modified with a graphical program.

So the File Modification Date/Time is changed.

I would like to copy the "Date Picture Taken" in "File Modification Date/Time".

I explain better I want to copy the exif information from "Date Picture Taken" to file information "File Modification Date/Time".

If it's possible I would like a commad to change all files in one time.

Thx

First, run exiftool -s FILE on one of your files to determine the tag names.  Then use a command like this to copy the value of one tag to the other:

exiftool "-filemodifydate<datetimeoriginal" DIR

This command will process all files in directory DIR.
