makemap -- create database maps for sendmail


makemap [-C file] [ -c cachesize ] [ -N ] [ -d ] [ -e ] [ -f ] [ -l ] [ -o ] [ -r ] [ -s ] [ -u ] [ -v ] maptype mapname


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 format maps

B-Tree format maps

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.


-C file
use the specified sendmail configuration file for looking up the TrustedUser option.

include the null byte that terminates strings in the map. This must match the -N flag in the K line.

-c cachesize
Use the specified hash and B-Tree cache size.

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.

Allow empty value (right hand side).

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 The value is never case folded.

List supported map types.

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.

Ignore safety checks on maps being created. This includes checking for hard or symbolic links in world writable directories.

dump (unmap) the contents of the database to standard output.

verbose option.
