MAKEMAP(8) OpenBSD System Manager's Manual MAKEMAP(8)NAMEmakemap - create database maps for sendmail
SYNOPSISmakemap [-C file] [-N] [-c cachesize] [-D commentchar] [-d] [-e] [-f]
[-l] [-o] [-r] [-s] [-t delim] [-u] [-v] maptype mapname
DESCRIPTIONmakemap 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 DBM format maps. This requires the ndbm(3) library.
btree B-Tree format maps. This requires the new Berkeley DB
library.
hash Hash format maps. This also requires the Berkeley DB
library.
In all cases, makemap reads lines from the standard input consisting of
two words separated by whitespace. 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.
Notice: do not use makemap to create the aliases data base, but
newaliases(8) which puts a special token into the data base that is
required by sendmail(8).
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.
Flags
-C file Use the specified sendmail(8) 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 Use the specified hash and B-Tree cache size.
-D Use to specify the character to use to indicate a comment
(which is ignored) instead of the default of `#'.
-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 behaviour. 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.
-t Use the specified delimiter instead of white space (also for
dumping a map).
-u dump (unmap) the content of the database to standard output.
-v Verbosely print what it is doing.
