NAME

6       dbformmail - write a shell script that will send e-mail to many people
7

SYNOPSIS

9       dbformmail [-m MECHANISM] format_file.txt
10

DESCRIPTION

12       Read a ``form mail'' message from the file FORMAT_FILE.TXT, filling in
13       underscore-preceded column-names with data.  Output a shell script
14       which will send each message through some mail transport MECHANISM.
15
16       Do not use this program for evil or I will have to come over and have
17       words with you.
18
19       Note that this program does NOT actually SEND the mail.  It writes a
20       shell script that will send the mail for you.  I recommend you save it
21       to a file, check it (one last time!), then run it with sh.
22
23       Unlike most Fsdb programs, this program does not output a FSDB file.
24

OPTIONS

26       -m MECHANISM
27           Select the mail-sending mechanism.  Choose "Mail" or "sendmail".
28           Defaults to "Mail".
29
30       This module also supports the standard fsdb options:
31
32       -d  Enable debugging output.
33
34       -i or --input InputSource
35           Read from InputSource, typically a file name, or "-" for standard
36           input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue
37           objects.
38
39       -o or --output OutputDestination
40           Write to OutputDestination, typically a file name, or "-" for
41           standard output, or (if in Perl) a IO::Handle, Fsdb::IO or
42           Fsdb::BoundedQueue objects.
43
44       --autorun or --noautorun
45           By default, programs process automatically, but Fsdb::Filter
46           objects in Perl do not run until you invoke the run() method.  The
47           "--(no)autorun" option controls that behavior within Perl.
48
49       --help
50           Show help.
51
52       --man
53           Show full manual.
