Hello.

I wish I could tell grep to stop searching in a file when it gets to a 
line matching something else. So if grep is searching a file for 'foo' 
then finds a line matching 'bar', stop searching for 'foo'. It would 
help me out a lot when searching for things in my perl modules where I 
do not want my perl pod searched.

LA

It may be out of the scope of GNU grep, but should be doable in perl -ln or=
 sed.
E.g (untested):

perl -ln -E '/bar/?exit:/foo/?say:0'
