makemap(1M)
makemap --
create database maps for sendmail
Synopsis
/etc/mail/makemap
[-Ndforv]
[maptype]
[mapname]
Description
makemap
creates the database maps used by the keyed map lookups in
sendmail(1M).
It reads input from the standard input
and outputs to the indicated
mapname.
Depending on how it is compiled,
makemap
handles up to three different database formats,
selected using the
maptype
parameter. The formats are:
- dbm
-
DBM format maps.
This requires the
ndbm(3bsd)
library.
- btree
-
B-Tree format maps. This
requires the new Berkeley
dbm(3bsd)
library.
- hash
-
Hash format maps.
This also requires the
dbm(3bsd)
library.
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 In
strings to indicate parameter substitution.
Literal parentheses should be doubled (( )).
Blank lines and lines beginning with # are ignored.
Options
- 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 uppercase letters in the key
are folded to lowercase.
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.
- 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 perform the insert.
- v
-
Verbosely print what makemap is doing.
