regarding lex regular expression

Hi all

I am using lex for my application scanning and I need to skip some lines for which I don't know the exact pattern.

So, could anybody tell me the regular expression to display lines NOT beginning with the specified pattern.

I know how to display lines beginning with the specified pattern.
For example,

^ABCD.* ---- It will match lines beginning with ABCD .....

Thanks in advance.

HI,
One method is you can mention the expected pattern one by one and at last have apettern . which means the pattern is not handled.
^ABCD {}
^XXXXX {}
. { Pattern which is not handled
This can be skipped
}

Thanks
