NAME

       makemap - create database maps for sendmail

SYNOPSIS

       makemap	[-C  file] [-N] [-c cachesize] [-d] [-D commentchar] [-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 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
       required 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.

   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 sendmail.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
       -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-
	      ries.

       -t     Use the specified delimiter instead of white space.

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

       -v     Verbosely print what it is doing.
