6 dbformmail - write a shell script that will send e-mail to many people
7
9 dbformmail [-m MECHANISM] format_file.txt
10
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
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.
54
56 Input:
57 #fsdb account passwd uid gid fullname homedir shell
58 johnh * 2274 134 John_Heidemann /home/johnh /bin/bash
59 greg * 2275 134 Greg_Johnson /home/greg /bin/bash
60 root * 0 0 Root /root /bin/bash
61 # this is a simple database
62
63 Sample form (in the file form.txt):
64
65 To: _account
66 From: the sysadmin <root>
67 Subject: time to change your password
68
69 Please change your password regularly.
70 Doesn't this message make you feel safer?
71
72 Command:
73 cat DATA/passwd.fsdb | dbformmail form.txt >outgoing.sh
74
75 Output (in outgoing.sh):
76 #!/bin/sh
77 sendmail 'johnh' <<'END'
78 To: johnh
79 From: the sysadmin <root>
80 Subject: time to change your password
81
82 Please change your password regularly.
83 Doesn't this message make you feel safer?
84
85 END
86 sendmail 'greg' <<'END'
87 (etc.)
88
89 And to send the mail, run
90
91 sh outgoing.sh
92
94 Fsdb.
