NAME

       makemap - Create database maps for sendmail

SYNOPSIS

       /usr/sbin/makemap [-N] [-d] [-f] [-o] [-r] [-v] maptype mapname

OPTIONS

       Include	the  null byte that terminates strings in the map.  This must match the -N option in the sendmail.cf K 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.   Nor-
       mally  all uppercase letters in the key are folded to lower case. This option disables that behavior.  This is intended to mesh with the -f
       option in the K line in sendmail.cf.  The value is never case folded.  Append to an old file.  This allows you to augment an existing file.
       Allow  replacement  of existing keys.  Normally makemap complains if you repeat a key, and does not do the insert.  Verbosely print what it
       is doing.

DESCRIPTION

       The makemap command 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.

       The  makemap  command  handles  three  different database formats, selected using the maptype operand.  They may be: DBM format maps.  This
       requires the ndbm library. See ndbm(3).	B-Tree format maps.  This requires the new Berkeley db library.   Hash	format	maps.	This  also
       requires the 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 indicated parameter substitution.	Literal percents should be  doubled  (%%).
       Blank lines and lines beginning with the pound sign (#) are ignored.
