-l (lowercase L)

List database types supported

makemap command-line switch

The -l switch tells makemap to print a list of the database types it supports, then exit. The largest list, and the most types that makemap can support, will look like this:

dbm    makemap compiled with NDBM defined
hash   makemap compiled with NEWDB defined
btree  makemap compiled with NEWDB defined

If in doubt, run makemap with this switch before trying to create a database file.
