This is essentially the function of grep on a Unix box. Grep has been
ported to almost all platforms by the GNU project (Stallman et al.,
www.gnu.org). For PC binaries of grep and a whole lot of other utilities
go to 
and look for djgpp. 

Just to clarify: djgpp is a programming environment -- gnu c and c++
compilers -- ported to PC. It has been used on the DOS/Windows PC
platform to compile the code for the utilities. The binaries, i.e.
compiled utilities, are also available under the djgpp pages (actually
one is supplied ftp URLs for a mirror near you).

While you are there, get gawk as well -- exceedingly useful for
functions such as you describe. It is less complicated, and less
powerful, than perl; its relative simplicity may recommend itself over
perl if you are not a programmer.
