obodiff

The obodiff utility compares a pair of OBO files and reports all of the edits necessary to transform the first file into the second. This utility is useful for detecting semantic changes in a file that may have superficial syntactic changes (such as rearranged terms and tags), and it can be used to track changes over several versions of an ontology. The command usage is:

obodiff [-o <outputfile>] [-t xml|text] <file1> <file2>

The command line parameters are:
