     makemap - create database maps for sendmail

     makemap [-N] [-d] [-f] [-o] [-r] [-s] [-v] maptype mapname

     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
     database  formats,  selected  using  the  maptype parameter.
They may be

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

     hash        Hash format maps.  This also requires the Berke-
ley DB li-

     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 ``#'' are ignored.


     -N          Include the null byte that terminates strings in
the map.
                 This  must  match the -N flag in the
``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 upper case letters in the  key  are
folded to low-
                 er  case.   This  flag  disables that behaviour.
This is intend-
                 ed to mesh with the -f flag in  the  K  line  in
                 The value is never case folded.

     -o           Append to an old file.  This allows you to aug-
ment an exist-
                 ing file.

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

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

     -v          Verbosely print what it is doing.


     The makemap command appeared in 4.4BSD.
