### NAME

cdbmake-sv - create a constant database from a `services` file

### SYNOPSIS

`cdbmake-sv` _f_ _ftmp_

### DESCRIPTION

`cdbmake-sv` is similar to `cdbmake`
but takes input in `/etc/services` format,
producing both forward and backward records
for each line.
For example, the input line

    discard 9/tcp sink null

maps `discard/tcp` to `9`,
maps `sink/tcp` to `9`,
maps `null/tcp` to `9`,
and maps `@9/tcp` to `discard`.

There is also a `cdb64make-sv` that uses cdb64 format instead of cdb format.
