it's unlikely that 1.4 will ship with support for db backends for
services, and if it does, the work this was going to do could be done with awk | makedbm ...

|
||||
.Os
|
||||
.Sh NAME
|
||||
.Nm services_mkdb
|
||||
.Nd generate the services databases
|
||||
.Sh SYNOPSIS
|
||||
.Nm
|
||||
.Op Fl o Ar database
|
||||
.Op file
|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
creates a
|
||||
.Xr db 3
|
||||
database for the specified file.
|
||||
If no file is specified, then
|
||||
.Pa /etc/services
|
||||
is used.
|
||||
The database is installed into
|
||||
.Pa /etc/services.db .
|
||||
The file must be in the correct format (see
|
||||
.Xr services 5 ).
|
||||
.Pp
|
||||
The options are as follows:
|
||||
.Bl -tag -width indent
|
||||
.It Fl o Ar database
|
||||
Put the output databases in the named file.
|
||||
.El
|
||||
.Pp
|
||||
The databases are used by the C library services routines (see
|
||||
.Xr getservent 3 ).
|
||||
.Pp
|
||||
.Nm
|
||||
exits zero on success, non-zero on failure.
|
||||
.Sh FILES
|
||||
.Bl -tag -width 24n -compact
|
||||
.It Pa /etc/services.db
|
||||
The current services database
|
||||
.It Pa /etc/services.db.tmp
|
||||
A temporary file
|
||||
.It Pa /etc/services
|
||||
The current services file
|
||||
.El
|
||||
.Sh BUGS
|
||||
Because
|
||||
.Nm
|
||||
guarantees not to install a partial destination file it must
|
||||
build a temporary file in the same file system and if successful use
|
||||
.Xr rename 2
|
||||
to install over the destination file.
|
||||
.Pp
|
||||
If
|
||||
.Nm
|
||||
fails it will leave the previous version of the destination file intact.
|
||||
