NAME
       makemap - create database maps for sendmail

SYNOPSIS
       makemap  [-C  file]  [-N]  [-c  cachesize]  [-d]  [-D com-
       mentchar] [-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  map-
       type parameter.  They may be

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

       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  configu-
       ration  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  send-
              mail.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 directories.

       -t     Use the specified delimiter instead of white space.

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

       -v     Verbosely print what it is doing.
