   5 NAME
   6        makemap - create database maps for sendmail

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

  14 DESCRIPTION
  15        makemap creates the database maps used by the keyed map lookups in
  16        sendmail(1M). makemap reads from the standard input and outputs to the
  17        specified mapname.
  18 
  19 
  20        In all cases, makemap reads lines from the standard input consisting of
  21        two words separated by whitespace. The first is the database key, the
  22        second is the value. The value may contain %n strings to indicate
  23        parameter substitution. Literal percents should be doubled (%%). Blank
  24        lines and lines beginning with # are ignored.
  25 
  26 
  27        Depending on how it is compiled, makemap handles up to three different
  28        database formats, selected using the maptype parameter. See OPERANDS.

  30 OPTIONS
  31        The following options are supported:
  32 
  33        -c cachesize
  34                          Use the specified hash and B-Tree cache size
  35                          (cachesize).
  36 
  37 
  38        -C file
  39                          Use the specified sendmail configuration file (file)
  40                          for looking up the TrustedUser option.
  41 
  42 
  43        -d
  44                          Allow duplicate keys in the map. This is only allowed
  45                          on B-Tree format maps. If two identical keys are
  46                          read, both are inserted into the map.
  47 
  48 
  49        -D commentchar
  50                          Use the specified character to indicate a comment
  51                          (which is ignored) instead of the default of '#'.
  52 
  53 
  54        -e
  55                          Allow empty value (right hand side).
  56 
  57 
  58        -f
  59                          Normally, all upper case letters in the key are
  60                          folded to lower case. This flag disables that
  61                          behavior. This is intended to mesh with the -f flag
  62                          in the K line in sendmail.cf. The value is never case
  63                          folded.
  64 
  65 
  66        -l
  67                          List supported map types.
  68 
  69 
  70        -N
  71                          Include the null byte that terminates strings in the
  72                          map. This must match the -N flag in the K line in
  73                          sendmail.cf.
  74 
  75 
  76        -o
  77                          Append to an old file. This allows you to augment an
  78                          existing file.
  79 
  80 
  81        -r
  82                          Allow replacement of existing keys. Normally makemap
  83                          complains if you repeat a key, and does not do the
  84                          insert.
  85 
  86 
  87        -s
  88                          Ignore safety checks on maps being created. This
  89                          includes checking for hard or symbolic links in world
  90                          writable directories.
  91 
  92 
  93        -t delim
  94                          Use the specified delimiter (delim) instead of
  95                          whitespace.
  96 
  97 
  98        -u
  99                          Dump (unmap) the content of the database to standard
 100                          output. Note that, if the -t option is also provided,
 101                          the specified delimiter is used when the content is
 102                          dumped instead of whitespace.
 103 
 104 
 105        -v
 106                          Verbosely print keys and values being added.
 107
