MMARCH(8)						      System Manager's Manual							 MMARCH(8)

NAME

       mmarch - Rebuild a Mailman mailing list's archive.

SYNOPSIS

       mmarch [options] <listname> [<mbox>]

DESCRIPTION

       Use  this  command  to rebuild the archives for a mailing list.	You may want to do this if you edit some messages in an archive, or remove
       some messages from an archive.

       -h, --help

	      Print this error message and exit.

       -q, --quiet

	      Make the archiver output less verbose.

       --wipe

	      First wipe out the original archive before regenerating.	You usually want to specify this argument unless you're generating the ar-
	      chive in chunks.

       -s N, --start=N

	      Start indexing at article N, where article 0 is the first in the mbox.  Defaults to 0.

       -e M, --end=M

	      End  indexing at article M.  This script is not very efficient with respect to memory management, and for large archives, it may not
	      be possible to index the mbox entirely.  For that reason, you can specify the start and end article numbers.

       mbox is the path to a list's complete mbox archive.  Usually this will be some path in the archives/private directory.  For example:

       % mmarch mylist archives/private/mylist.mbox/mylist.mbox

       mbox is optional.  If it is missing, it is calculated.

AUTHOR

       Author of Mailman is  the  Mailman  Cabal,  see	http://www.list.org/  for  information.  This  manpage	is  written  by  Tollef  Fog  Heen
       <tfheen@debian.org> for Debian, but may be used by others.
