This is possible with sed, awk, perl, and probably a zillion other
tools, depending on exactly what you want to do.  But none of these are
part of GNU coreutils, they are their own projects.  However, any system
that has coreutils installed will likely have at least one of them as
well.

sed -e 's,search,replace,g'
perl -pe 's,search,replace,g'
awk '{ gsub(/search/, "replace"); print }'

That's way too generic of a description to really be able to offer any
concrete advice.
