I'm using Exiftool 8.65 on Windows 7 64 bit.
I'm trying to read for example date when photo was taken (DateTimeOriginal) from JPG file.
Source code looks something like this (because whole program is written in C#):
exiftool.exe -stay_open true -@ -
C:\Test\DSC02129.JPG
-groupNames
-veryShort
--printConv
-fast
-ignoreMinorErrors
-q
-q
-EXIF:DateTimeOriginal
-execute0
-stay_open
false
Output looks like this:
[EXIF] DateTimeOriginal: 2009:12:27 10:03:52
But I think it should be:
[EXIF] DateTimeOriginal: 2009:12:27 10:03:52
{ready0}
It is caused by "-q" option and I this it's a bug.
From the -stay_open documentation:
3) Write "-execute\n" to ARGFILE, where "\n" represents a newline
sequence. (Note: You may need to flush your write buffers here if
using buffered output.) Exiftool will then execute the command
with the arguments received up to this point, send a "{ready}"
message to stdout when done (unless the -q option is used), and
continue trying to read arguments for the next command from
ARGFILE. To aid in command/response synchronization, any number
appended to the "-execute" option is echoed in the "{ready}" mes-
sage. For example, "-execute613" results in "{ready613}".
If you really need the -q option, then add a second -execute0 to execute a null command afterwards for the "{ready0}" response.

Thanks for replay, I didn't noticed this fragment when I was reading some time ago :)
