makemap - create database maps for sendmail
makemap [-C file] [-N] [-c cachesize] [-D commentchar] [-d]
[-e] [-f]
[-l] [-o] [-r] [-s] [-t delim] [-u] [-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 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 [Toc] [Back]
-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 BTree
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.
-u dump (unmap) the content of the database to
standard output.
-v Verbosely print what it is doing.
