argfile

[jween]

Hello friends
I'm trying to figure out how to use the argfile to extract particular tags to enter into a database. I used to list all the tags on the command line but trying to clean up the code.

So I'm using the command line:

exiftool -r -@ RecArgs /Path/test.photoslibrary/originals/*

and RecArgs file contains

Code Select Expand

-filename
-filename (yes, I want a duplicate)
...more tags
-shutterspeed
-aperture
But I get errors like

Code Select Expand

Invalid TAG name: "filename "
Invalid TAG name: "filename "
...more errors
Invalid TAG name: "shutterspeed "
======== /PATH/test.photoslibrary/originals/3/37057B42-BF21-4714-95C3-B2F050E80B5A.jpeg
Aperture                        : 4.0
So, wondering why this seems to work for the "-aperture" tag but not the others?
Is this just not the way to do this?

Thanks!
Cheers
Jon

Invalid TAG name: "shutterspeed "

Notice the position of the quotes.  You have a trailing space.  You're trying to print a tag name that has a space on the end, which will always fail.

From the docs on the -@ (Argfile) option (emphasis mine)
    Normal shell processing of arguments is not performed, which among other things means that arguments should not be quoted and spaces are treated as any other character

Well, duh.
Sorry, and thanks!

Oh it absolutely is not a "duh".  I've made that mistake so often it's the first thing I double check.
