Pylagiarist is a plagiate detection script written in Python.
It recursively scans folders for files whose names match a certain pattern, compares each pair of files, and reports those whose similarity is beyond a given threshold.
Pylagiarist uses difflib's SequenceMatcher to compute similarities. If python-Levenshtein is installed, it also reports Levenshtein ratios for similar files.

to learn about them.

.htm, but not matching
pylagiarist -i '.html$' -i '.htm$' -x index src1 src2
Report similarities above 0.4 (computed by difflib)
pylagiarist -t 0.4
