NAME
       makemap - create database maps for sendmail

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

DESCRIPTION
       makemap	creates	 the  database	maps  used by the keyed map lookups in
       sendmail(1M). 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.

OPTIONS
       The following options are supported:

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

       -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
			 folded.

       -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
			 sendmail.cf

       -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 delim
			 Use the specified delimiter (delim) instead of white‐
			 space.

       -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.

OPERANDS
       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.
