NAME

       makemap - creates database maps for sendmail

SYNOPSIS

       file] maptype mapname

DESCRIPTION

       creates	the  database  maps used by the keyed map lookups in sendmail(1M).  It reads input from the standard input and outputs them to the
       indicated mapname.

       handles up to three different database formats, selected using the maptype parameter.  They may be:

	      DBM format maps. (.pag,.dir)

	      B-Tree format maps. (.db)

	      Hash format maps. (.db)

       In all cases, 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 strings to indicated parameter substitution.  Literal parentheses should be doubled Blank lines
       and lines beginning with pound sign are ignored.

   Flags
       Use the specified
	       configuration file to look up the option.

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

       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.

       Allow empty value (right hand side).

       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 flag in the line in The  value	is
	       never case folded.

       Create NIS compatible alias database.

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

       Allow replacement of existing keys.
	       Normally complains if you repeat a key, and does not do the insert.

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

       Dump (unmap) the content of the database to standard output.

       Verbosely print what it is doing.
