NAME

makemap − creates database maps for sendmail

SYNOPSIS

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

DESCRIPTION

makemap 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.

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

dbm DBM format maps. (.pag,.dir)

btree B-Tree format maps. (.db)

hash Hash format maps. (.db)

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 parentheses should be doubled (%%).  Blank lines and lines beginning with pound sign (#) are ignored. 

Flags

-N Include the null byte that terminates strings in the map.  This must match the −N flag in the sendmail.cf K line. 

-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. 

-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 sendmail.cf.  The value is never case folded. 

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

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

-v Verbosely print what it is doing.
