Which database methods in Drupal are used most often?

gistfile1.sh

# Grep for db_select and grab the next 5 lines
# grep and sed those lines to find db methods
# isolate the methods
# count them.
# I ran this in the core: modules/ directory, would be interesting to see results from a mix of sites/all/modules/ directories
