@(#)makemap.8 6.1 (Berkeley) 12/21/92

C 6 .sh NAME makemap - create database maps for sendmail makemap [ -N ] [ -f ] [ -o ] [ -r ] [ -v ] maptype mapname 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 format maps. This requires the ndbm (3) library. B-Tree format maps. This requires the new Berkeley db (3) library. Hash format maps. This also requires the db (3) 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 parentheses should be doubled (``%%''). Blank lines and lines beginning with ``#'' are ignored.

Include the null byte that terminates strings in the map. This must match the -N flag in the sendmail.cf ``K'' line. Fold all upper case letters in the key to lower case; this is intended to mesh with the -f flag in the K line in sendmail.cf. The value is not 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. sendmail(8)
