makemap(8)
NAME
  makemap - Create database maps for sendmail

SYNOPSIS
  /usr/sbin/makemap [-N] [-d] [-f] [-o] [-r] [-v] maptype mapname

DESCRIPTION
  The makemap command creates the database maps used by the keyed map lookups
  in sendmail(8).  It reads input from the standard input and outputs them to
  the indicated mapname.

  Depending on how it is compiled, makemap handles up to three different
  database formats, selected using the maptype parameter.  They may be

  dbm	    DBM format maps.  This requires the ndbm(3) library.

  btree	    B-Tree format maps.	 This requires the new Berkeley dbm(3)
	    library.

  hash	    Hash format maps.  This also requires the dbm(3) library.

  In all cases, makemap 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 %n strings to indicated parameter
  substitution.	 Literal percents should be doubled (%%).  Blank lines and
  lines beginning with the pound sign (#) are ignored.

FLAGS
  -N	    Include the null byte that terminates strings in the map.  This
	    must match the -N flag in the sendmail.cf K line.

  -d	    Allow duplicate keys in the map.  This is only allowed on B-Tree
	    format maps.  If two identical keys are read, they will both be
	    inserted into the map.

  -f	    Normally all uppercase letters in the key are folded to lower
	    case.  This flag disables that behavior.  This is intended to
	    mesh with the -f flag in the K line in sendmail.cf.	 The value is
	    never case folded.

  -o	    Append to an old file.  This allows you to augment an existing
	    file.

  -r	    Allow replacement of existing keys.	 Normally makemap complains
	    if you repeat a key, and does not do the insert.

  -v	    Verbosely print what it is doing.


RESTRICTIONS
  As provided by DIGITAL, only dbm maps are supported.
