MAKEMAP(8)
NAME
makemap - create database maps for sendmail
SYNOPSIS
makemap [-N] [-d] [-f] [-o] [-r] [-s] [-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
btree B-Tree format maps. This requires the new
Berkeley DB li-
brary.
hash Hash format maps. This also requires the Berke-
ley DB li-
brary.
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 ``#'' 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 low-
er case. This flag disables that behaviour.
This is intend-
ed 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 aug-
ment an exist-
ing 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.
-v Verbosely print what it is doing.
