DESCRIPTION
 netgroup_mkdb creates a 
db(3) database for the specified file. If no file is specified, then 
/etc/netgroup is used. This database is installed into 
/var/db/netgroup.db. The file must be in the correct format (see 
netgroup(5)).
The options are as follows:
- 
-o database
- 
Put the output databases in the named file.
The databases are used by the C library netgroup routines (see getnetgrent(3)).
netgroup_mkdb exits zero on success, non-zero on failure.
 
BUGS
 Because 
netgroup_mkdb guarantees not to install a partial destination file it must build a temporary file in the same file system and if successful use 
rename(2) to install over the destination file.
If netgroup_mkdb fails it will leave the previous version of the destination file intact.
