### NAME

services_mkdb - generate the services databases

### SYNOPSIS

services_mkdb [-q] [-o database] [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.db`. The file must be in the correct format (see services(5)).

The options are as follows:

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

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

-q
  Don't 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 successful use rename(2) to install over the destination file.

If services_mkdb fails it will leave the previous version of the destination file intact.
