Extract every record except
 

I know how to extract every record that contains a pattern:

grep "404" <f1> > <f2>

But is there a way to extract every record that doesn't contain the pattern?

Thanks.

Hi,

Read the man page of grep and pay special attention to the -v option.


Cheers,

Thanks. Just to leave an example:

echo "$(grep -v "\*" <f1>)"

This displayed every line in file <f1> that didn't contain an asterisk.
