svn propset svn:externals "$(svn propget svn:externals . -r HEAD)" .
this sets the property to the HEAD value. This is a valid workaround since revert
can only be applied to all properties, and doesn't exist for individual properties.
Using ExifTool (portable executable renamed to exiftool.exe):
exiftool -ImageSize -r .
Here ImageSize is the tag name you're interested in and will print Image Width x Image Height. The -r
switch makes it recursively process files in subdirectories.
Custom output string format is simple as well. For example:
exiftool -p "Image Name: \"$FileName\"$/Image Size: $ImageSize$/" -r .
In this case the tag names are preceded by $. $/
prints a newline.
Note: The commands above have to be typed at the command prompt. To redirect the output to a text file you can append > Details.txt
to them.
If you want to simply run the program and have it write a text file with the relevant image details, you can rename the executable as follows:
ExifTool(-FileName -Imagesize -w+! %0fDetails.txt -ext gif --ext exe .).exe
This will write all console output (-w
) to a file named Details.txt in the current directory. In this case the output will consist of the image names and sizes for all GIFs in the current directory. Further details about the -w
parameter, including the meaning of +
, !
and %0f
are available at the documentation link above.
You can include more extensions to be processed using -ext jpg -ext png
and so on, or delete -ext gif
altogether to make it read all supported file types (including non-images which you may not want).
--ext exe
is used to exclude all EXEs (so that the program's own executable isn't included in the report).
-r
can of course be added to enable recursive processing.
There is lots more you can do with the program given how ridiculously powerful it is (and extensible too given that the full Perl source is freely available)!

Check out this link where James O'Neill creates a powershell script to get at any of the extended properties. He uses it to get at all the camera properties stored in a file, but Title is one of them.
