Loop through file and write out lines to file(s)
Hi,
I am new to ksh scripting so your help will be much appreciated.
I have a file called file.txt which looks like this
Header 20050702 20050703
ABC
DEF
Header 20050703 20050704
123
456
Header 20050704 20050705
XXX
YYY
What I am trying to do is write out each of the record sets to its own file. For example, file1.txt will contain:
Header 20050702 20050703
ABC
DEF
and file2.txt will contain:
Header 20050703 20050704
123
456
etc.
What is the best way to approach this?
Thank you in advance.

encode::mime::header
Encode::MIME::Header(3pm) User Contributed Perl Documentation Encode::MIME::Header(3pm)
NAME
Encode::MIME::Header -- MIME 'B' and 'Q' header encoding
SYNOPSIS
use Encode qw/encode decode/;
$utf8 = decode('MIME-Header', $header);
$header = encode('MIME-Header', $utf8);
ABSTRACT
This module implements RFC 2047 Mime Header Encoding. There are 3 variant encoding names; "MIME-Header", "MIME-B" and "MIME-Q". The
difference is described below
decode() encode()
----------------------------------------------
MIME-Header Both B and Q =?UTF-8?B?....?=
MIME-B B only; Q croaks =?UTF-8?B?....?=
MIME-Q Q only; B croaks =?UTF-8?Q?....?=
DESCRIPTION
When you decode(=?encoding?X?ENCODED WORD?=), ENCODED WORD is extracted and decoded for X encoding (B for Base64, Q for Quoted-Printable).
Then the decoded chunk is fed to decode(encoding). So long as encoding is supported by Encode, any source encoding is fine.
When you encode, it just encodes UTF-8 string with X encoding then quoted with =?UTF-8?X?....?= . The parts that RFC 2047 forbids to
encode are left as is and long lines are folded within 76 bytes per line.
BUGS
It would be nice to support encoding to non-UTF8, such as =?ISO-2022-JP? and =?ISO-8859-1?= but that makes the implementation too
complicated. These days major mail agents all support =?UTF-8? so I think it is just good enough.
Due to popular demand, 'MIME-Header-ISO_2022_JP' was introduced by Makamaka. Thre are still too many MUAs especially cellular phone
handsets which does not grok UTF-8.
