If you ever want to delete a bunch of log groups:

$ aws --profile ProfileName logs describe-log-groups --output table | awk '{print $6}' | grep lambdaNamePrefix | sed -E "s/(.*)/aws --profile ProfileName logs delete-log-group --log-group-name \1/"

PS. This only returns a number of delete-log-group commands but does not execute them. DS.
