.TH MAKEMAP 8 "Jan 21, 2019"
.SH NAME
makemap \- create database maps for sendmail
.SH SYNOPSIS
.LP
.nf
\fBmakemap\fR [\fB-N\fR] [\fB-d\fR] [\fB-f\fR] [\fB-o\fR] [\fB-r\fR] [\fB-s\fR] [\fB-v\fR] [\fB-C\fR \fIfile\fR]
     [\fB-c\fR \fIcachesize\fR] [\fB-D\fR \fIcommentchar\fR] [\fB-e\fR] [\fB-l\fR] [\fB-t\fR \fIdelim\fR]
     [\fB-u\fR] \fImaptype\fR \fImapname\fR
.fi

.SH DESCRIPTION
.LP
\fBmakemap\fR creates the database maps used by the keyed map lookups in
\fBsendmail\fR(8). \fBmakemap\fR reads from the standard input and outputs to
the specified \fImapname\fR.
.sp
.LP
In all cases, \fBmakemap\fR reads lines from the standard input consisting of
two words separated by whitespace. The first is the database key, the second is
the value. The value may contain \fB%\fR\fIn\fR strings to indicate parameter
substitution. Literal percents should be doubled (\fB%%\fR). Blank lines and
lines beginning with \fB#\fR are ignored.
.sp
.LP
Depending on how it is compiled, \fBmakemap\fR handles up to three different
database formats, selected using the \fImaptype\fR parameter. See
\fBOPERANDS\fR.
.SH OPTIONS
.LP
The following options are supported:
.sp
.ne 2
.na
\fB-c\fR \fIcachesize\fR
.ad
.RS 18n
Use the specified hash and B-Tree cache size (\fIcachesize\fR).
.RE

.sp
.ne 2
.na
\fB-C\fR \fIfile\fR
.ad
.RS 18n
Use the specified \fBsendmail\fR configuration file (\fIfile\fR) for looking up
the \fBTrustedUser\fR option.
.RE

.sp
.ne 2
.na
\fB-d\fR
.ad
.RS 18n
Allow duplicate keys in the map. This is only allowed on B-Tree format maps. If
two identical keys are read, both are inserted into the map.
.RE

.sp
.ne 2
.na
\fB-D\fR \fIcommentchar\fR
.ad
.RS 18n
Use the specified character to indicate a comment (which is ignored) instead of
the default of '\fB#\fR'.
.RE

.sp
.ne 2
.na
\fB-e\fR
.ad
.RS 18n
Allow empty value (right hand side).
.RE

.sp
.ne 2
.na
\fB-f\fR
.ad
.RS 18n
Normally, all upper case letters in the key are folded to lower case. This flag
disables that behavior. This is intended to mesh with the \fB-f\fR flag in the
\fBK\fR line in \fBsendmail.cf\fR. The value is never case folded.
.RE

.sp
.ne 2
.na
\fB-l\fR
.ad
.RS 18n
List supported map types.
.RE

.sp
.ne 2
.na
\fB-N\fR
.ad
.RS 18n
Include the null byte that terminates strings in the map. This must match the
\fB-N\fR flag in the \fBK\fR line in \fBsendmail.cf\fR.
.RE

.sp
.ne 2
.na
\fB-o\fR
.ad
.RS 18n
Append to an old file. This allows you to augment an existing file.
.RE

.sp
.ne 2
.na
\fB-r\fR
.ad
.RS 18n
Allow replacement of existing keys. Normally \fBmakemap\fR complains if you
repeat a key, and does not do the insert.
.RE

.sp
.ne 2
.na
\fB-s\fR
.ad
.RS 18n
Ignore safety checks on maps being created. This includes checking for hard or
symbolic links in world writable directories.
.RE

.sp
.ne 2
.na
\fB-t\fR \fIdelim\fR
.ad
.RS 18n
Use the specified delimiter (\fIdelim\fR) instead of whitespace.
.RE

.sp
.ne 2
.na
\fB-u\fR
.ad
.RS 18n
Dump (unmap) the content of the database to standard output. Note that, if the
\fB-t\fR option is also provided, the specified delimiter is used when the
content is dumped instead of whitespace.
.RE

.sp
.ne 2
.na
\fB-v\fR
.ad
.RS 18n
Verbosely print keys and values being added.
.RE

.SH OPERANDS
.LP
The following operands are supported:
.sp
.ne 2
.na
\fImapname\fR
.ad
.RS 11n
File name of the database map being created.
.RE

.sp
.ne 2
.na
\fImaptype\fR
.ad
.RS 11n
Specifies the database format. The following \fImaptype\fR parameters are
available:
.sp
.ne 2
.na
\fBdbm\fR
.ad
.RS 9n
Specifies \fBDBM\fR format maps.
.RE

.sp
.ne 2
.na
\fBbtree\fR
.ad
.RS 9n
Specifies B-Tree format maps.
.RE

.sp
.ne 2
.na
\fBhash\fR
.ad
.RS 9n
Specifies hash format maps.
