NAME

6       makemap - create database maps for sendmail
7

SYNOPSIS

9       makemap  [-C  file] [-N] [-c cachesize] [-d] [-D commentchar] [-e] [-f]
10       [-l] [-o] [-r] [-s] [-t delim] [-u] [-v] maptype mapnam

DESCRIPTION

13       Makemap creates the database maps used by  the  keyed  map  lookups  in
14       sendmail(8).   It  reads input from the standard input and outputs them
15       to the indicated mapname.
16
17       Depending on how it is compiled, makemap handles up to three  different
18       database formats, selected using the maptype parameter.  They may be
19
20       btree  B-Tree format maps.  This requires the new Berkeley DB library.
21
22       hash   Hash format maps.  This also requires the Berkeley DB library.
23
24       In all cases, makemap reads lines from the standard input consisting of
25       two words separated by white space.  The first is the database key, the
26       second  is the value.  The value may contain ``%n'' strings to indicate
27       parameter substitution.  Literal percents should be  doubled  (``%%'').
28       Blank lines and lines beginning with ``#'' are ignored.
29
30       Notice:  do  not  use  makemap  to  create  the  aliases data base, but
31       newaliases which puts a special  token  into  the  data  base  that  is
32       required by sendmail.
33
34       If the TrustedUser option is set in the sendmail configuration file and
35       makemap is invoked as root, the generated files will be  owned  by  the
36       specified TrustedUser.
37
38   Flags
39       -C     Use the specified sendmail configuration file for looking up the
40              TrustedUser option.
41
42       -N     Include the null byte that terminates strings in the map.   This
43              must match the -N flag in the sendmail.cf ``K'' line.
44
45       -c     Use the specified hash and B-Tree cache size.
46
47       -D     Use to specify the character to use to indicate a comment (which
48              is ignored) instead of the default of '#'.
49
50       -d     Allow duplicate keys in the map.  This is only allowed on B-Tree
51              format  maps.  If two identical keys are read, they will both be
52              inserted into the map.
53
54       -e     Allow empty value (right hand side).
55
56       -f     Normally all upper case letters in the key are folded  to  lower
57              case.   This  flag disables that behaviour.  This is intended to
58              mesh with the -f flag in the K line in sendmail.cf.   The  value
59              is never case folded.
60
61       -l     List supported map types.
62
63       -o     Append  to  an old file.  This allows you to augment an existing
64              file.
65
66       -r     Allow replacement of existing keys.  Normally makemap  complains
67              if you repeat a key, and does not do the insert.
68
69       -s     Ignore  safety  checks  on  maps  being  created.  This includes
70              checking for hard or symbolic links in world  writable  directo‐
71              ries.
72
73       -t     Use  the  specified  delimiter  instead of white space (also for
74              dumping a map).
75
76       -u     dump (unmap) the content of the database to standard output.
77
78       -v     Verbosely print what it is doing.
