netgroup_mkdb(8)

netgroup_mkdb8

Generate the netgroup databases

Usage

netgroup_mkdb [-o database] [file]

Overview

netgroup_mkdb creates Berkeley databases for the specified file. If no file is specified, /etc/netgroup is used. These databases are then installed into /etc/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)).

Files

/etc/netgroup.db

current netgroup database

/etc/netgroup.db.tmp

a temporary file

/etc/netgroup

current netgroup file

Exit status

The netgroup_mkdb utility exits 0 on success, and >0 if an error occurs.

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.
