MAKEMAP(8)		 BSD System Manager's Manual		    MAKEMAP(8)

NAME
     makemap - create database maps for sendmail

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

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 li-
		 brary.

     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 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.

     Notice: do not use makemap to create the aliases data base, but
     newaliases(8) which puts a special token into the data base that is re-
     quired by sendmail(8).

     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 file	 Use the specified sendmail(8) 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 in-
		 tended to mesh with the -f flag in the "K" line in
		 sendmail.cf. The value is never case folded.

     -l		 List supported map types.

     -o		 Append to an old file. This allows you to augment an existing
		 file.
     -r		 Allow replacement of existing keys. Normally makemap com-
		 plains 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 direc-
		 tories.

     -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.
