Sometimes exporting a collection from MongoDB adds the database prefix into the name. So, if you want to obtain the collection name from the filename containing the prefix database_name.collection_name you can do the following:

# echo the filename property and pipe the result into cut command. 
# then obtain the second part of the text after the '.' character,
collection_name=$(echo $col | cut -d"." -f2)

echo "importing $collection_name"

# use that as a collection name during import 
mongoimport -d edgraph -c "$collection_name" --file "$col.json" --jsonArray
