Name
-d
Synopsis
Ordinarily, makemap
will complain if two entries have identical keys and refuse to insert
the duplicate. But if it is desirable to allow the same key to appear
multiple times in the database, you can use the -d
switch to suppress the warnings and allow duplicates to be inserted.
But be aware that this switch is allowed only for the
btree
and hash
forms of the
db(3) library. Use of this switch with any other
form of database will produce the following error:
makemap: Type dbtype
does not support -d (allow dups)
See the -r
switch for a way to cause duplicates to
replace originals.
