services_mkdb

SERVICES_MKDB(8)					    BSD System Manager's Manual 					  SERVICES_MKDB(8)

NAME

     services_mkdb -- generate the services databases

SYNOPSIS

     services_mkdb [-qv] [-o database] [-V style] [file]
     services_mkdb -u [file]

DESCRIPTION

     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 for-
     mat (see services(5)).

     The options are as follows:

     -o database
	     Put the output databases in the named file.

     -q      Don't warn about duplicate services.  This is the default behavior.

     -u      Print the services file to stdout, omitting duplicate entries and comments.

     -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 for-
	     mat.  The DB format is useful for compatibility with old statically linked binaries.

     -v      Warn about duplicate services.

     The databases are used by the C library services routines (see getservent(3)).

     services_mkdb exits zero on success, non-zero on failure.

FILES

     /var/db/services.db       The current services database.
     /var/db/services.db.tmp   A temporary file.
     /etc/services	       The current services file.

SEE ALSO

     db(3), getservent(3), services(5)

BUGS

     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 destination file intact.
