( ns tokenize (:import ( java.io BufferedReader FileReader ))) ( defn process-file [file-name] ( with-open [rdr ( BufferedReader. ( FileReader. File-name )) ] ( doseq [line ( line-seq rdr ) ] ( println line )))) ( process-file 'tokenize.clj' ) The BufferedReader wraps the FileReader to provide a lazy interface to the file, and allows us to treat the stream as a list, while behind the scene it calls the readLine method on BufferedReader.

( ns tokenize (:use [clojure.contrib.duck-streams:only ( read-lines ) ] )) ( defn process-file [file-name line-func line-acc] ( reduce line-func line-acc ( read-lines file-name ))) ( defn process-line [acc line] ( reduce #( assoc%1%2 ( + ( get%1%2 0 ) 1 )) acc (. Split line ' ' ))) ( prn ( process-file 'tokenize.clj' process-line ( hash-map ))) It's a bit more compact, but probably you'd be using duck-streams.read-lines because you were already using other duck-streams functionality (like for writing out files, for appending to files). There are many other approaches to reading in files in Clojure, but these should be enough to get started.
