Duplicate java class finder Finds java classes with same name and counts occurrences

duplication.sh

# Find all java classes in tree. (including auto-generated classes in 'target' folders:

find . -name "*.java" | xargs  egrep -o "class [A-Z]\w+"  | awk '{print $2}' | sort | uniq -c | sort -n | grep -v 1



# Use git (faster). 
#Ignores any auto-generated classes since they are typically inside ignored 'target' folders 
git grep --extended-regexp --no-index  "class [A-Z]\w+" | egrep -o "class [A-Z]\w+" | awk '{print $2}' | sort | uniq -c | sort -n | grep -v 1




#example output:
find . -name "*.java" | xargs  egrep -o "class [A-Z]\w+"  | awk '{print $2}' | sort | uniq -c | sort -n | grep -v 1
