dbformmail - write a shell script that will send e-mail to many people
SYNOPSISdbformmail [-m MECHANISM] format_file.txt
DESCRIPTIONRead a ``form mail'' message from the file FORMAT_FILE.TXT, filling in underscore-preceded column-names with data. Output a shell script which will send each message through some mail transport MECHANISM.
Do not use this program for evil or I will have to come over and have words with you.
Note that this program does NOT actually SEND the mail. It writes a shell script that will send the mail for you. I recommend you save it to a file, check it (one last time!), then run it with sh.
- -m MECHANISM
- Select the mail-sending mechanism. Choose ``Mail'' or ``sendmail''. Defaults to ``Mail''.
This module also supports the standard fsdb options:
- Enable debugging output.
- -i or --input InputSource
- Read from InputSource, typically a file name, or "-" for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.
- -o or --output OutputDestination
- Write to OutputDestination, typically a file name, or "-" for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.
- --autorun or --noautorun
- By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The "--(no)autorun" option controls that behavior within Perl.

Sample form (in the file form.txt):
To: _account From: the sysadmin <root> Subject: time to change your password Please change your password regularly. Doesn't this message make you feel safer?
cat DATA/passwd.fsdb | dbformmail form.txt >outgoing.sh
Output (in outgoing.sh):
#!/bin/sh sendmail 'johnh' <<'END' To: johnh From: the sysadmin <root> Subject: time to change your password Please change your password regularly. Doesn't this message make you feel safer? END sendmail 'greg' <<'END' (etc.)
And to send the mail, run
