Overwriting EXIF and File info from filenames in YYYYMMDD_HHMMSS format.

[sjw]

Hi, could you please tell me the exiftool command to populate the FileModifyDate, FileCreateDate, DateTimeOriginal, CreateDate and ModifyDate (-alldates) tags for a file named like 20160825_180532.jpg ?  Use of -overwrite_original is fine.
Many thanks!

exiftool "-alldates<filename" "-filemodifydate<filename" "-filecreatedate<filename" FILE

Many thanks Phil - I was waaaay overthinking it!

[Phil Harvey]

Yes.  ExifTool applies some smarts when writing date/time values (see FAQ 5).

Thanks again.
I assume the exact same command would work if the same named files had prefixes of IMG_ for example yes?

Yes.  All you need is the 14 numbers for the full date/time in the correct sequence without any numbers preceding them.  All other characters will be ignored.

Many thanks again!
If I wish to recursively scan sub folders I can add -r.  How do I make it only consider jpg files?
-r pathname/*.jpg isn't quite right.

Use the -ext (-extension) option.
