If it’s cross platform compatibility you’re after, I suppose programming it in Java would be fairly attractive solution. But, there are some folks that claim perl is a completely legitimate cross platform programming language…

Derek, I’ve been working on a similar project and wonder if you could help me. The details are here: https://sites.google.com/site/kanyimbe/ubiqivo.

Basically the idea is that I want a platform independent way to create an index.htm file containing a list of all the files in a directory with their metadata. A friend made this work with perl but I believe that won’t work for everyone.

Do you have any idea how we might make this happen?

Many thanks,

David

I suppose you could add in your script an if…then statement that checks if the file is empty:

if [ -s $FILE ] ; then
   echo "$FILE has data."
else
   echo "$FILE is empty."
fi

Thanks. If the output file is empty the tag was not found.
Make sure your images actually have tags. In my case, digiKam does not write the tags to the image file but rather stores that information in a database. This can be corrected in configuration and subsequently using the “write metadata to each file” command from the metadata panel’s “more” dropdown at the bottom.

[...] Re: digiKam, Gwenview, and tagging You don't have to re-check the tags manually. Once the above mentioned setting is activated, in the Caption/Tags pane or sidebar or dock or whatever the More dropdown at the bottom, featuring the command "write metadata to each file" actually does what it's suggesting. I guess it only updates digiKams database otherwise. This is a real sucker! digiKam should warn the user that it actually stores the metadata somewhere else..
