.Sh DESCRIPTION
|
|
.Nm
|
|
creates the database maps used by the keyed map lookups in
|
|
.Xr sendmail 8 .
|
|
It reads input from the standard input
|
|
and outputs them to the indicated
|
|
.Ar mapname .
|
|
.Pp
|
|
Depending on how it is compiled,
|
|
.Nm
|
|
handles up to three different database formats,
|
|
selected using the
|
|
.Ar maptype
|
|
parameter.
|
|
They may be
|
|
.Bl -tag -width Fl
|
|
.It Li dbm
|
|
DBM format maps.
|
|
This requires the
|
|
.Xr ndbm 3
|
|
library.
|
|
.It Li btree
|
|
B-Tree format maps.
|
|
This requires the new Berkeley
|
|
.Xr db 3
|
|
library.
|
|
.It Li hash
|
|
Hash format maps.
|
|
This also requires the
|
|
.Xr db 3
|
|
library.
|
|
.El
|
|
.Pp
|
|
In all cases,
|
|
.Nm
|
|
reads lines from the standard input consisting of two
|
|
words separated by white space.
|
|
The first is the database key,
|
|
the second is the value.
|
|
The value may contain
|
|
``%\fIn\fP''
|
|
strings to indicated parameter substitution.
|
|
Literal parentheses should be doubled
|
|
(``%%'').
|
|
Blank lines and lines beginning with ``#'' are ignored.
|
|
.Ss Flags
|
|
.Bl -tag -width Fl
|
|
.It Fl N
|
|
Include the null byte that terminates strings
|
|
in the map.
|
|
This must match the \-N flag in the sendmail.cf
|
|
``K'' line.
|
|
.It Fl f
|
|
Fold all upper case letters in the key
|
|
to lower case;
|
|
this is intended to mesh with the
|
|
\-f flag in the
|
|
\fBK\fP
|
|
line in sendmail.cf.
|
|
The value is not case folded.
|
|
.It Fl o
|
|
Append to an old file.
|
|
This allows you to augment an existing file.
|
|
.It Fl r
|
|
Allow replacement of existing keys.
|
|
Normally
|
|
.Nm
|
|
complains if you repeat a key,
|
|
and does not do the insert.
|
|
.It Fl v
|
|
Verbosely print what it is doing.
