NAME
       makemap - create database maps for sendmail

SYNOPSIS
       makemap	[-C file] [-N] [-c cachesize] [-d] [-D commentchar] [-e] [-f]
       [-l] [-o] [-r] [-s] [-t delim] [-u] [-v] maptype mapnam

DESCRIPTION
       Makemap 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

       btree  B-Tree format maps.  This requires the new Berkeley DB library.

       hash   Hash format maps.	 This also requires the Berkeley DB  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
       indicate parameter substitution.	 Literal percents should  be  doubled
       (''%%'').  Blank lines and lines beginning with ''#'' are ignored.

       Notice:	do  not	 use  makemap  to  create  the aliases data base, but
       newaliases which puts a special token  into  the	 data  base  that  is
       required by sendmail.

       If  the	TrustedUser  option is set in the sendmail configuration file
       and makemap is invoked as root, the generated files will be  owned  by
       the specified TrustedUser.

   Flags
       -C     Use  the	specified  sendmail configuration file for looking up
	      the TrustedUser option.

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

       -c     Use the specified hash and B-Tree cache size.

       -D     Use  to  specify	the  character	to  use to indicate a comment
	      (which is ignored) instead of the default of '#'.

       -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.

       -e     Allow empty value (right hand side).

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

       -l     List supported map types.

       -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.

       -s     Ignore  safety  checks  on  maps	being created.	This includes
	      checking for hard or symbolic links in world writable  directo-
	      ries.

       -t     Use the specified delimiter instead of white space.

       -u     dump (unmap) the content of the database to standard output.

       -v     Verbosely print what it is doing.
