May 20, 2007 NETGROUP_MKDB 8

### NAME

netgroup_mkdb - generate the netgroup database

### SYNOPSIS

netgroup_mkdb [-o database] [file]

### 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.

### FILES

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

### SEE ALSO

db(3), getnetgrent(3), netgroup(5)

### 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.
