I have two ODT documents, they have very close contents, I want to compare them to see how similar they are.
The best would be to have a similarity percentage, if not possible, an alternative would be at least to have some sort of diff.
I am running Ubuntu Lucid.
odt2txt to convert the files to text, then used
wdiff -i --statistics one.txt two.txt to have a diff along with statistics which gave me the percentage of common words (similarity).
