dbformmail - write a shell script that will send e-mail to many people¶
NOTE: this page was directly converted from the perl FSDB manual pages from FSDB version 3.1
SYNOPSIS¶
dbformmail [-m MECHANISM] format_file.txt
DESCRIPTION¶
Read 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.
Unlike most Fsdb programs, this program does not output a FSDB file.
OPTIONS¶
- -m MECHANISM
Select the mail-sending mechanism: Mail, sendmail, mh. Defaults to Mail. Mail uses a Berkeley-style /usr/bin/Mail. Sendmail invokes /usr/bin/sendmail. Mh writes messages into the current directory, treating it as an mh-style mailbox (one message per file, with filesnames as sequential integrates).
This module also supports the standard fsdb options:
- -d
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)autorunoption controls that behavior within Perl.
- --help
Show help.
- --man
Show full manual.
