Can ExifTool write just the time without date?

[Phil Harvey]

Yes, but it isn't in the command you typed here:

Okay - yes, you're correct - I've tried it both ways; however, with or without the dot the problem has been seen:

[Phil Harvey]

Now that's a bummer.

I did a search in the forum for "Config file not found", and it was only ever a problem with the path specification.

Are you sure that ExifTool has read permissions for the config file on your system?  I can't see why it shouldn't.

Try entering this command:

type CONFIGFILENAME

where CONFIGFILENAME is the name of your config file.

If that works, then I can imagine no reason why this would give a "Config file not found" error:

exiftool -config CONFIGFILENAME -date -time test.jpg

Well... that at least the type command worked

... and I take it the "exiftool" command still gave the "Config file not found" error?

What version of exiftool are you using, btw?  (type "exiftool -ver")

- Phil

[kbellis]

Yep - still not found

Version returned:
9.46

[Phil Harvey]

This is getting silly.

OK.  Try just parsing the config file with exiftool (no -config option):

exiftool CONFIGFILE

ExifTool should at least return some system information about the file.

If it can find the file like this, then it should be able to find it as part of the -config option.  If it can't then there is something deeper going on.

Good test - another clue .. though I'm not exactly sure what to make of it:

Phil,

Is it permissible to use the -config argument for anything other than .ExifTool_config; say for example:
exiftool -config date_time_config

I woke up thinking about ExifTool deciding the what I've been using was "unknown" and wondering, what if I just start from scratch?

Along the same line of starting fresh, I tried this:

Code Select Expand

echo "BaseName<tab>ShutterSpeed<tab>Aperture<tab>ISO" > %1\out.txt
C:\ExifTool\exiftool -config C:\ExifTool\Image-ExifTool-946\config_files\.ExifTool_config -T -r -n -basename -dateTimeOriginal -shutterspeedvalue -aperturevalue -ISO %1 >> %1\out.txt


That's the original factory default version without any of my hacks.

Eureka! It worked!!!

Okay, so the next thing then using TextPad was to shoehorn in the hack:

Code Select Expand

# breakup date and time
# see thread: https://exiftool.org/forum/index.php/topic,5560.0.html
#
# return the date from a date/time string
Date => {
    Require => {
                0 => 'DateTimeOriginal',
            },
    ValueConv => '$val =~ s/ .*//; $val',
        },
        # return the time from a date/time string
Time => {
    Require => {
                0 => 'DateTimeOriginal',
            },
    ValueConv => '$val =~ s/.* //; $val',
},
#       
        # It's all Phil from here

But not alter the calls in the bat just to see if that hack fetched things up - it didn't; it also ran perfectly.

Now to try using the revised bat with the calls to the two hacked arguments:

Code Select Expand

echo "BaseName<tab>Date<tab>Time<tab>ShutterSpeed<tab>Aperture<tab>ISO" > %1\out.txt
C:\ExifTool\exiftool -config C:\ExifTool\Image-ExifTool-946\config_files\.ExifTool_config -T -r -n -basename -date -time -shutterspeedvalue -aperturevalue -ISO %1 >> %1\out.txt


Oh, and look at that; it works great!

As for what in the heck was going on... man, I have no clue and truth be told I don't care to get into the necropsy; however, an explicit path beyond the home directory of exiftool may help in pinning down the reason for the issue.

Bottom line, thanks for being here and for the marvelous support on top of making this totally awesome tool!

Now onto the next custom tags!
Day_to_x
EV_base
EV_ISO
EV_to_y

But I'll save that for another thread


Kind regards,

Hi Kelly,

I'm glad you got it working, although we really still don't know what the problem was.  I thought the problem was likely due to file permissions, but the exiftool output shows that you do have read permissions for the file.

Anyway, it works now.  Good work.

- Phil

[kbellis]

As for what in the heck was going on... man, I have no clue and truth be told I don't care...

I guess I lied 

Still thinking about this, I tried another experiment with the working config copied to the home directory c:\ExifTool and then calling for it without thinking that I had to call for its complete path since it was in the same directory - Nope, didn't work. But adding the call for the full path - worked fine.

Go figyah.

And props to our youngest son for the suggestion on our way back to UMF yesterday 

[Phil Harvey]

Yes, you need to specify the path if the directory is different from the current working directory.  (The "pwd" command will print the current working directory.)

But this doesn't explain the problem because the path must also be specified for the "type" command we tried, unless you were running these commands from different working directories (which would sort of defeat the point of this test).

- Phil

[kbellis]

pwd is not recognized

Yes.. it's still a mystery, just ain't gnawing away as much

[Phil Harvey]

Hmmm.  I thought that "pwd" worked in Windows too, but I guess not.  Googling this, just typing "cd" with no arguments should work.

- Phil
