NAME spmail - splits a Berkeley-style mailbox into separate files SYNOPSIS spmail [-s start] [-p path] mbox spmail [-m|-w|-d|-h|-y] [-p path] mbox spmail -v DESCRIPTION spmail splits a Berkeley-style mail file "mbox" into separate files by message, day, hour, week, month, or year. In all cases, a directory called data/mbox is created to hold the individual messages, where mbox is the basename of the original mail file. Splitting by Message The first form of the command creates sub-directories beneath data/mbox with the names "0", "1", ... The first sub-directory (0) contains files with the names "001" through "999". Each remaining sub-directory contains files with the names "000" through "999". Each file con- tains a single mail message. Splitting by Date If splitting by date, mail is appended to files beneath data/mbox as follows: If splitting by output mailbox name looks like day YYYY-MM-DD hour YYYY-MM-DDHH month YYYY-MM week YYYYwNN year YYYY OPTIONS -v prints the version number and exits. -s num accepts a number at which the file creation is to begin. Default is 0. Only valid when splitting by message. -p path accepts a pathname which is to serve as the top- level directory, instead of "data/mbox". -d splits mailbox by day. -h splits mailbox by hour. -m splits mailbox by month. -w splits mailbox by week. -y splits mailbox by year. NOTES The regular expression used to search for the start of a mail message is "\n\nFrom .* (Jan|Feb|...|Nov|Dec) .* [0-9][0-9]:[0-9][0-9]" ERRORS Exits with If 0 Everything is OK. 1 Usage error. 2 Problem finding the mailbox file to split. EXAMPLES Splitting by message: These examples assume the existence of a file called sample containing 63 mail messages in Berkeley format, with dates ranging from 15 October 1995 to 19 July 1996. % ls -l data ls: data: No such file or directory % ls -l sample -rw-r--r-- 1 mail mail 221667 Nov 21 1997 sample % spmail sample % ls -R data data/sample: 0 data/sample/0: 001 009 017 025 033 041 049 057 002 010 018 026 034 042 050 058 003 011 019 027 035 043 051 059 004 012 020 028 036 044 052 060 005 013 021 029 037 045 053 061 006 014 022 030 038 046 054 062 007 015 023 031 039 047 055 063 008 016 024 032 040 048 056 Splitting by date: % spmail -d sample opening 1995-10-15 opening 1995-11-17 opening 1995-12-01 opening 1995-12-12 ... % (cd ./data/sample; ls -l) -rw-r--r-- 1 bin bin 725 Dec 15 17:25 1995-10-15 -rw-r--r-- 1 bin bin 1319 Dec 15 17:25 1995-11-17 -rw-r--r-- 1 bin bin 672 Dec 15 17:25 1995-12-01 -rw-r--r-- 1 bin bin 2191 Dec 15 17:25 1995-12-12 ... -rw-r--r-- 1 bin bin 948 Dec 15 17:25 1996-06-23 -rw-r--r-- 1 bin bin 1834 Dec 15 17:25 1996-06-24 -rw-r--r-- 1 bin bin 498 Dec 15 17:25 1996-07-01 -rw-r--r-- 1 bin bin 19496 Dec 15 17:25 1996-07-19 % spmail -w sample opening 1995w41 opening 1995w46 opening 1995w48 opening 1995w50 opening 1996w10 opening 1996w12 ... opening 1996w27 opening 1996w29 % (cd ./data/sample; ls -l) -rw-r--r-- 1 bin bin 725 Dec 15 17:25 1995w41 -rw-r--r-- 1 bin bin 1319 Dec 15 17:25 1995w46 -rw-r--r-- 1 bin bin 672 Dec 15 17:25 1995w48 -rw-r--r-- 1 bin bin 2191 Dec 15 17:25 1995w50 -rw-r--r-- 1 bin bin 19495 Dec 15 17:25 1996w10 -rw-r--r-- 1 bin bin 19496 Dec 15 17:25 1996w12 -rw-r--r-- 1 bin bin 20520 Dec 15 17:25 1996w13 -rw-r--r-- 1 bin bin 19495 Dec 15 17:25 1996w14 -rw-r--r-- 1 bin bin 22806 Dec 15 17:25 1996w16 -rw-r--r-- 1 bin bin 20946 Dec 15 17:25 1996w17 -rw-r--r-- 1 bin bin 20080 Dec 15 17:25 1996w18 -rw-r--r-- 1 bin bin 16949 Dec 15 17:25 1996w19 -rw-r--r-- 1 bin bin 1016 Dec 15 17:25 1996w20 -rw-r--r-- 1 bin bin 4095 Dec 15 17:25 1996w22 -rw-r--r-- 1 bin bin 25274 Dec 15 17:25 1996w23 -rw-r--r-- 1 bin bin 1930 Dec 15 17:25 1996w24 -rw-r--r-- 1 bin bin 948 Dec 15 17:25 1996w25 -rw-r--r-- 1 bin bin 1834 Dec 15 17:25 1996w26 -rw-r--r-- 1 bin bin 498 Dec 15 17:25 1996w27 -rw-r--r-- 1 bin bin 19496 Dec 15 17:25 1996w29 AUTHOR Karl Vogel Sumaria Systems, Inc.
