Re: deleting that maillist footer

$q means "quit if last line of file".
 

 Here is a similar, simpler way that I think works, even as a somewhat long one-liner:
 

 $ cat input.txt
Hello, Dan!!!
 ------------------------------------
Posted by: Sven Guckes <sven@...>
------------------------------------

 

 $ cat sed.txt
/^-----*$/ {N; /Posted by:/ {N; /------$/ d } }

 

 $ sed -f sed.txt input.txt
Hello, Dan!!!
