[Solved] How to append date to filename, but base it on yesterday's date?
Hello,
I'd like to write a monthly archive script that archives some logs. But I'd like to do it based on yesterday's date. In other words, I'd like to schedule the script to run on the 1st day of each month, but have the archive filename include the previous month instead.
Here's what I have so far (this works for current day):
So the format ends up being: filename_2013-09(Sep).tar.gz
I'd like to be able to run a script on October 1st and have it say that.
And I'd like to run the same script on November 1st and have it end up with a filename_2013-10(Oct).tar.gz
Thanks!

SYNOPSIS
chewmail [OPTIONS] <MAILBOX> ...
DESCRIPTION
chewmail is a program for archiving mail. It is inspired by the by the Python-based archivemail, but with more useful semantics. All mail
is archived to the mailbox specified with the --output-box switch, in mbox format. It can read mailboxes in mbox, Maildir and MH formats.
Internally, chewmail uses Mail::Box, so it support file names and URLs supported by that module.
OPTIONS -o mailbox-format, --output-box=mailbox-format
The mailbox to archive messages to. The mailbox is run through the Date::Format module, so it supports all it's conversion specifiers.
The date and time is relative to the messages timestamp, or the current time if the timestamp is impossible to determine. A sample of
the conversion specifiers follows:
%% PERCENT
%b month abbr
%B month
%d numeric day of the month, with leading zeros (eg 01..31)
%e numeric day of the month, without leading zeros (eg 1..31)
%D MM/DD/YY
%G GPS week number (weeks since January 6, 1980)
%h month abbr
%H hour, 24 hour clock, leading 0's)
%I hour, 12 hour clock, leading 0's)
%j day of the year
%k hour
%l hour, 12 hour clock
%L month number, starting with 1
%m month number, starting with 01
%n NEWLINE
%o ornate day of month -- "1st", "2nd", "25th", etc.
%t TAB
%U week number, Sunday as first day of week
%w day of the week, numerically, Sunday == 0
%W week number, Monday as first day of week
%x date format: 11/19/94
%y year (2 digits)
%Y year (4 digits)
-d days-old, --days=days-old
Only archive messages older than than this many days.
-D date, --date=date
Only archive messages old than this date. The date can be any date understood by Perl's Date::Parse module.
-R, --only-read
Only archive messages that are marked seen or read.
--delete-immediately
Synchonize the mailboxes after every message is moved. This will be substantially slower but may provide better recovery for some mail-
box formats in the event of a crash.
--preserve-timestamp
Preserve the atime and mtime of the input mailbox. This only affects file-based mailboxes, such as mbox.
-n, --dry-run
Go through all the motions of archiving the mail, but don't actually change any mailboxes.
-v, --verbose
Output more informational messages. Use multiple times for more verbosity.
-q, --quiet
Don't output any messages other than error messages.
-V, --version
Print the version number then exit.
-h, --help
Print usage information then exit.
EXAMPLES
Archive two day old messages in inbox to inbox-old:
chewmail --days 2 -o inbox-old inbox
Archive read messages to a mailbox named the year-month of the message:
chewmail --only-read -o %Y-%m inbox
