For example, I have 25 MB Postfix log file which I've wrote a script that
extracts the IDs for a specific from <> address, then use fgrep to extract
the logs specific to that domain. 

That process takes about 5 minutes to process 17,000 unique IDs. 

If I use the -v invert, then it's another 5 minutes to generate a new list.
I figure that if fgrep scans a file line by line for a match, there would be
a way to process those that didn't match into another file to save time from
re-processing the script.

If there's not a utility to do this, I could write the procedure in Perl
that replicated what fgrep does, but I wanted to be sure that there isn't a
utility out there already.

Are you just asking about &quot;fgrep -v&quot; ?

&gt; I have a list of PostFix IDs in a file that I'm able to fgrep the initial
&gt; maillog and return all entries matching the IDs in the list. I'd like to
&gt; create two files with it though, one that contains the new maillog that
&gt; matches the IDs listed in the file and another file that contains the old
&gt; maillog without these lines.
&gt;
&gt;
&gt;
&gt; Any idea how I would go about accomplishing this? Thanks.
