services_mkdb -- generate the services databases
services_mkdb [-qv] [-o database] [-V style] [file]
services_mkdb -u [file]
services_mkdb creates a db(3) database for the specified file. If no
file is specified, then /etc/services is used. The database is installed
into /var/db/services.cdb for CDB format and into /var/db/services.db for
DB format (see -V). The file must be in the correct format (see
The options are as follows:

-q Don't warn about duplicate services. This is the default behav-
-u Print the services file to stdout, omitting duplicate entries and
-V Create a specific version of the database style. style can be
cdb to request the CDB format (default) or db to request the DB
format. The DB format is useful for compatibility with old stat-

services_mkdb exits zero on success, non-zero on failure.
/var/db/services.db The current services database.
/var/db/services.db.tmp A temporary file.
/etc/services The current services file.
db(3), getservent(3), services(5)
Because services_mkdb guarantees not to install a partial destination
file it must build a temporary file in the same file system and if suc-
cessful use rename(2) to install over the destination file.
If services_mkdb fails it will leave the previous version of the destina-
tion file intact.
