       makemap - create	database maps for sendmail

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

       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

       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  re-
       quired 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.

       -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	``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   The	 value
	      is never case folded.

       -l     List supported map types.

       -o     Append  to  an old file.	This allows you	to augment an existing

       -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-

       -t     Use  the	specified  delimiter  instead of white space (also for
	      dumping a	map).

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

       -v     Verbosely	print what it is doing.

       sendmail(8), newaliases(1)

       The makemap command appeared in 4.4BSD.
