Try:
Code:

sed "s/three.*chickens //g" get.txt

No, your idea won't work, it would replace the 1st keyword
with the second globally.

[edit]heh - beat by twenty seconds :}[/edit]
What you want to do is
s/keyword1.*keyword2//g



Cheers,
Tink

what if
 
what if I wanted to do the same thing, but remove 's/keyword1.*keyword2//g' but leave keyword1 & keyword2 in place.

using keyword1 and 2 as references btw, cause I could easily use the words before&after each :)

I want to remove like s/[a-z].*$//g
that will remove the h at the end, how can I leave that....
