Is there any way to have a column heading in a file manaher -- I prefer Krusader, but Konqueror if I must -- list a file's creation date rather than its modified date? I'm sorting and marking something on the order of a million photographs, and the creation date is of use, while the modified date will soon be all last week and this week, rendering the date useless.
In Krusader I can eliminate the column entirely, but not have it list the creation date.

Linux file systems don't record the file creation date.

Well, that kinda sucks. EXIF maintains a creation date that's accessible from numerous photo applications, but those applications are universally awful for file-management purposes. Maybe there's a script someplace that will overright modified date with creation date. Not a thing everyone would want to do, but useful in a variety of circumstances. -- dep

In case this is useful to you... it is a little script that sets the modification time of a JPEG to its EXIF time (which would then give you the date you seem to want in your file manager). If you save it to a file called "set-photo-time" and give it execute perms, then you can run it as follows: set-photo-time file1.jpg file2.jpg file3.jpg file4.jpg ... It requires the "exif" program, which you may or may not already have installed. It works for me, but use at your own risk.
Cheers. Jim

Many thanks -- that seems to be exactly what I need. I'll copy a directory of pictures into a temp directory, run it there, and if it plays nicely I'll use it!
<rant>I used gThumb for a long time, but they've improved it to near uselessness (and destructiveness, unless you go in and turn a lot of things off; I've been a large part of the last week finding and deleting .comments directories whose very existence implies that the pictures will never be seen except in gThumb), and I guess digiKam is useful for some purposes, but it is also bloatware and for many purposes pretty much needs a dedicated computer. Oh, to be able to turn off its database aspects! It relies on its database rather than what's actually present on the computer -- delete a directory in any file manager and it's still listed in digiKam until the database is rerun; last time I did that here, on a fairly quick computer, it took more than 40 hours to complete. I don't know what digiKam users want to do with their pictures, but it ain't what I want to do. As it is, photography is 1/60 second to make a picture and an hour to file it on the computer!</rant> -- dep

Hi Jim!
That's neat, love it :)

Although looking at that, it's been up-rev'ed, so attaching the last version, but do read its comments in the code before running.

It might be that "exiftool" already has the functionality needed - quote from the man page:
exiftool '-FileModifyDate<DateTimeOriginal' dir Use the original date from the meta information to set the same file's filesystem modification date for all images in a directory.

A problem with unconstrained exiftool is that to be safe it makes a copy of each file it modifies, so there's generally a lot of cleaning up to do after running it.

Not in this case, just put some images in a temprary folder and run:
$ exiftool '-FileModifyDate<DateTimeOriginal' .
.. nothing to clean up :)
