#Approach 1
find . -name "autoencoder_class_*.*" -exec /bin/rm -i {} \;
find . -name "tf_model.h5" -exec /bin/rm -i {} \;

#Approach 2
#1. Display the big files in descending order of size
find . -type f -exec du -h {} + | sort -rh | head -n 20

#2. Delete the files displayed in step 1, one by one
find . -type f -exec du -h {} + | sort -rh | head -n 20 | awk '{print $2}' | xargs -i -p rm '{}'
