Question How can I ... (Modifying large ASCII files)

Hi Everybody!

Situation:
I have a large ASCII file (for example: 1-2 Mbytes) without linebreaks (\n).

Task:
I like inserting linebreaks after all 420 digits (byte).
(pattern: *[420pcs]\n*[420pcs]\n*[420pcs]\n...etc.)

My problem:
How? :-)
I like using shell script or (maybe) AWK (short) program.

Please, help me.

Bye
hviktor

html2stx(1)						      General Commands Manual						       html2stx(1)

NAME
html2stx - convert HTML documents into Stx SYNOPSIS
html2stx [ file ] DESCRIPTION
html2stx takes the given file, which should contain an HTML document, and converts it to structured text (Stx). If no file is given, stan- dard input is read instead. The program does not attempt to convert every possibly convertible piece of markup into Stx. For example, <font> tags are simply ignored. This tends to result in a nice, clean, beautiful document. (If it doesn't, the source document probably does not contain enough informa- tion to start with.) OPTIONS
None. DIAGNOSTICS
html2stx is a python script and will throw an exception if something goes amiss. In this case, the return value will be non-zero. SEE ALSO
stx2any (1), Stx-ref.html BUGS
o The word wrapping algorithm is probably not very clever. o Sometimes there are extra linebreaks in the output. o Probably many others. AUTHOR
This manual page was written by Panu A. Kalliokoski. html2stx is derived from the html2text utility by Aaron Swartz. html2text is a utility for converting html into "Markdown" structured text; the changes required to make it work for Stx were done by Panu Kalliokoski.
