echo "
This bash script takes all the .csv files in the folder and performs classification using weka.
The classifiers used are: J48, J48graft, RandomForest and RandomTree. 10 fold cross validation 
is performed. The classification output are saved as text files along with the models.
The .csv files must be present in the same folder along with this script.
