You might want to look up the function "readFile" in the Prelude.  

I must admit that while I've been using Haskell for odd bits and ends
for a while now, I've not yet used a file handle -- still a lot of
posted code seems to use them.  Is this a creeping C-ism, or are
handles genuinely useful, even if you simply are reading the content
of a file to process it (i.e. typical Unix shell util usage)?

If I haven't seen further, it is by standing in the footprints of giants
