'-if' and 'FileName', why does not work togeter?

[marcogaio]

I need to move/reorganize some photo, but filtering them by date (eg, older then...).

Photo metadata seems OK:

Code Select Expand


root@eraldo:~# exiftool -a -G1 -s -time:all /home/gaio/Immagini/arthur/2019/10/IMG_20191020_102048.jpg

[Composite]     SubSecDateTimeOriginal          : 2019:10:20 10:20:49.000820


and if i try simply to search, the '-if' works:

Code Select Expand


root@eraldo:~# exiftool -r -if '$DateTimeOriginal le "2018:02:22"' /home/gaio/Immagini/arthur/2019/10/IMG_20191020_102048.jpg
    1 files failed condition
root@eraldo:~# exiftool -r -if '$DateTimeOriginal le "2020:02:22"' /home/gaio/Immagini/arthur/2019/10/IMG_20191020_102048.jpg

[...]


But if i try to combine the '-if' with 'TestFile' (i've done also a test with 'FileName', and photo get effectively moved away...) seems that the 'if' condition does not match:

Code Select Expand


root@eraldo:~# exiftool -r -if '$DateTimeOriginal le "2018:02:22"' "-TestName<DateTimeOriginal" -d "/srv/casa/Foto/%Y/%m/%d/gaio-%%f.%%e" /home/gaio/Immagini/arthur/2019/10/IMG_20191020_102048.jpg

I'm a bit puzzled... thanks.

The problem is that you are reformatting the date/time with -d, which also applies to $DateTimeOriginal in your -if condition.

Change $DateTimeOriginal to $DateTimeOriginal# in your -if condition to avoid reformatting the date/time here.

A-Ha! Bingo!

Sorry, i've read i think carefully docs and manpage, but i've totally missed that.

In hindsight, the line in -TAG section of the manpage:

Code Select Expand


A "#" may be appended to the tag name to disable the print conversion on a per-tag basis (see the -n option).  This may also be used when writing or copying tags.

looks relevant.

Thanks.
