EXR metadata reader?

[Ihno]

Hi, does anybody know a tool that can read the metadata of an EXR sequence and give me a list of all the frames a specific node has rendered?

I unfortaunatly discovered there is something wrong with a node but I already rendered a bunch of sequences and for some reason Backburner lost the information.

I think the ExifTool will do the trick. I'm folowing this tutorial because she's outputting an CSV file which is great.

do my commandline right now is:
exiftool -filename -vrayInfo/computername -T -CSV -ext exr C:\Users\IhnoO\Desktop\exiftest >C:\Users\IhnoO\Desktop\exiftest\out.csv

unfortunatly it throws this error:
Invalid TAG name: "vrayInfo/computername"

Could it be that it cant handle the slash in the computername tag?

EDIT:
I found out it woks by simply removing the slash so the final commandline looks like this:

exiftool -filename -Vrayinfocomputername -CSV -ext exr "image directory">"csv output directory\csvfilename.csv"

for example like this:
exiftool -filename -Vrayinfocomputername -CSV -ext exr C:\Users\IhnoO\Desktop\exiftest >C:\Users\IhnoO\Desktop\exiftest\out.csv
