# nbp(1)

tools for accessing the NBP database

## Name

nbplkup, nbprgstr, nbpunrgstr — tools for accessing the NBP database

## Synopsis

**nbplkup**

**nbprgstr** \[-A *address*\] \[-m *Mac charset*\] \[-p *port*\] *obj:type@zone*

**nbpunrgstr** \[-A *address*\] \[-m *Mac charset*\] *obj:type@zone*

## Description

**nbprgstr** registers *nbpname* with [**atalkd**(8)](/atalkd/8.md), at the given *port*. **nbpunrgstr** informs **atalkd** that *nbpname* is no longer to be advertised.

**nbplkup** displays up to *maxresponses* (default 1000) entities registered on the AppleTalk internet. *nbpname* is parsed by [**nbp\_name**(3)](/nbp_name/3.md). An \`*=*’ for the *object* or *type* matches anything, and an \`*\**’ for *zone* means the local zone. The default values are taken from the NBPLKUP environment variable, parsed as an *nbpname*.

## Environment Variables

NBPLKUP

default nbpname for nbplkup

ATALK\_MAC\_CHARSET

the codepage used by the clients on the Appletalk network

ATALK\_UNIX\_CHARSET

the codepage used to display extended characters on this shell.

## Examples

Find all devices of type *LaserWriter* in the local zone.
