Hi everyone, I hope that someone can help me out:

In the following line:

PRIHDR;2809999444;2007 6.1;20070423;9;;4021473000003;;4021473000003;8714231530688;EUR;;

The output should be:

PRIHDR;2809999444;2007 6.1;20070423;4;;4021473000003;;4021473000003;8714231530688;EUR;;

I've tried some variations on the following command:

sed 's/;9;;/;4;;' <oldfile>newfile

When I run this command it tells met what to do with the ";" how can I solve this issue?

Thanks in advance,

IHulky

p.s. the other lines in the document (line 2 and further) have to be copied as well to the new file.
