Shell Programming and Scripting

hi all
i have a some huge html files (500MB to 1GB). Each file has multiple
<html></html> tags

<html>
.................
....................
....................
</html>
<html>
.................
....................
....................
</html>
<html>
.................
....................
....................
</html>
..........
..........

I want to split these html files into smaller files with <html> in the beginning and </html> at the end

<html>
.......
.......
</html>
<html>
..........
..........
</html>

Kindly suggest me a perl/awk/sed or any shell script solution.

Thanks and Regards,

hi franklin,
how can i create multiple file from a huge html file?

i tried this

awk '/<html>/{n++}{print >"output" n ".html" }' input.html

but splitting is not proper. one file should contain many <html> </html> sets

Thanks and Regards,
uttam

Try this:

awk '
/<html>/{close("file"c".html");c++}
{print $0 > "file"c".html"}
' file
