makemap(ADMN)
makemap --
create database maps for sendmail
Syntax
makemap [-C file] [ -c cachesize ] [ -N ] [ -d ] [ -e ] [ -f ] [ -l ] [ -o ]
[ -r ] [ -s ] [ -u ] [ -v ] maptype mapname
Description
makemap creates the database maps used by the
keyed map lookups in
sendmail(ADMN).
It reads input from the standard input and outputs them to
the indicated mapname.
makemap handles three different database formats,
selected using the maptype parameter. They may
be:
dbm-
DBM format maps
btree-
B-Tree format maps
hash-
hash format maps
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 percent signs should be doubled
(``%%'').
Blank lines and lines beginning with ``#'' are ignored.
If the TrustedUser
option is set in the sendmail configuration file and
makemap
is invoked as root, the generated files will be owned by
the specified
TrustedUser.
Options
-C file-
use the specified sendmail configuration file
for looking up the TrustedUser option.
-N-
include the null byte that terminates strings
in the map.
This must match the -N flag in the sendmail.cf
K line.
-c cachesize-
Use the specified hash and B-Tree cache size.
-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.
-e-
Allow empty value (right hand side).
-f-
Normally, all upper case letters in the key are
folded to lower case.
This flag disables that behavior.
This is intended to mesh with the
-f
flag in the
K
line in
sendmail.cf.
The value is never case folded.
-l-
List supported map types.
-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.
-s-
Ignore safety checks on maps being created. This includes
checking for hard or symbolic links in world writable directories.
-u-
dump (unmap) the contents of the database to standard output.
-v-
verbose option.
