I'm looking on how to apply a regex on a pretty huge input text (a file
that's a couple of gigabytes). I found finditer which would return results
iteratively which is good but it looks like I still need to send a string

on a file?
Any help would be appreciated.
You can call *grep* posix utility.
Does not grep only work a line at a time? Just like the code below?
But if the regex's matches are possible only inner the context of a
line of that file:
#<code>
res = []
with file(filename) as f:
for line in f:
res.extend(getmatches(regex, line))
# Of course "getmatches" describes the concept.
