       makemap - create database maps for sendmail

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

       makemap  creates  the  database  maps  used by the keyed map lookups in
       sendmail(8). makemap reads from the standard input and outputs  to  the
       specified mapname.

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

       makemap  handles  three  different database formats. Database format is
       selected using the maptype parameter. See OPERANDS.

       The following options are supported:

       -c cachesize      Use the specified hash and B-Tree cache size  (cache-

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

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

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

       -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  behav-
                         ior. This is intended to mesh with the -f flag in the
                         K line  in  sendmail.cf.  The  value  is  never  case

       -l                List supported map types.

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

       -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

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

       -t delim          Use the specified delimiter (delim) instead of white-

       -u                Dump  (unmap) the content of the database to standard
                         output. Note that, if the -t option is also provided,
                         the  specified  delimiter is used when the content is
                         dumped instead of whitespace.

       -v                Verbosely print what it is doing.

       The following operands are supported:

       mapname    File name of the database map being created.

       maptype    Specifies the database format. The following maptype parame-
                  ters are available:

                  dbm      Specifies DBM format maps.

                  btree    Specifies B-Tree format maps.

                  hash     Specifies hash format maps.

       |      ATTRIBUTE TYPE         |       ATTRIBUTE VALUE        |
