DESCRIPTION
makemap
creates the database maps used by the keyed map lookups in
sendmail(1M).
It reads input from the standard input
and outputs them to the indicated
mapname.
makemap
handles up to three different database formats,
selected using the
maptype
parameter.
They may be
- dbm
DBM format maps. (.pag,.dir)
- btree
B-Tree format maps. (.db)
- hash
Hash format maps. (.db)
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 parentheses should be doubled
(%%).
Blank lines and lines beginning with pound sign
(#)
are ignored.
Flags
- -N
Include the null byte that terminates strings
in the map.
This must match the
-N
flag in the
sendmail.cf K
line.
- -n
Create NIS compatible alias database.
- -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 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.
- -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.
- -v
Verbosely print what it is doing.
HISTORY
The
makemap
command appeared in 4.4BSD.
