- default to /etc/netgroup if no input file is specified. - create a temporary file and rename that to the final destination, so the we don't get partially created netgroup files. Fixes PR bin/963.

|
.Os
|
|
.Sh NAME
|
|
.Nm netgroup_mkdb
|
|
.Nd generate the netgroup databases
|
|
.Sh SYNOPSIS
|
|
.Nm netgroup_mkdb
|
|
.Op Fl o Ar database
|
|
.Op file
|
|
.Sh DESCRIPTION
|
|
.Nm Netgroup_mkdb
|
|
creates
|
|
.Xr db 3
|
|
style databases for the specified file. If no file is specified, then
|
|
.Pa /etc/netgroup
|
|
is used.
|
|
These databases are then installed into
|
|
.Pa /etc/netgroup.db.
|
|
The file must be in the correct format (see
|
|
.Xr netgroup 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 netgroup routines (see
|
|
.Xr getnetgrent 3 ).
|
|
.Pp
|
|
.Nm Netgroup_mkdb
|
|
exits zero on success, non-zero on failure.
|
|
.Sh FILES
|
|
.Bl -tag -width 24n -compact
|
|
.It Pa /etc/netgroup.db
|
|
The current netgroup database
|
|
.It Pa /etc/netgroup.db.tmp
|
|
A temporary file
|
|
.It Pa /etc/netgroup
|
|
The current netgroup file
|
|
.El
|
|
.Sh BUGS
|
|
Because
|
|
.Nm 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
|
|
.Xr rename 2
|
|
to install over the destination file.
|
|
.Pp
|
|
If
|
|
.Nm netgroup_mkdb
|
|
fails it will leave the previous version of the destination file intact.
