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: Mail, sendmail, mh.  Defaults to
28           "Mail".
29
30           Mail uses a Berkeley-style /usr/bin/Mail.  Sendmail invokes
31           /usr/bin/sendmail.  Mh writes messages into the current directory,
32           treating it as an mh-style mailbox (one message per file, with
33           filesnames as sequential integrates).
34
35       This module also supports the standard fsdb options:
36
37       -d  Enable debugging output.
38
39       -i or --input InputSource
40           Read from InputSource, typically a file name, or "-" for standard
41           input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue
42           objects.
43
44       -o or --output OutputDestination
45           Write to OutputDestination, typically a file name, or "-" for
46           standard output, or (if in Perl) a IO::Handle, Fsdb::IO or
47           Fsdb::BoundedQueue objects.
48
49       --autorun or --noautorun
50           By default, programs process automatically, but Fsdb::Filter
51           objects in Perl do not run until you invoke the run() method.  The
52           "--(no)autorun" option controls that behavior within Perl.
53
54       --help
55           Show help.
56
57       --man
58           Show full manual.
