sed not printing lines before a regular expression.
Hey, I found a way to print the lines which is just before a regular expression, not including the expression.

Code:
sed -n '/regexp/{n;p;}'  myfile

Now I'm looking for a way to print all lines, exept the regular expression and also the line before the same regular expression.

I am not sure if I understand what you want because your explanation is in my eyes a bit different from what the command does. Maybe a grep -v is sufficient?
Else you might want to post an example of your input and wanted output.
