Here's one I wrote probably needs revisited
(defn doCmd
"do any command"
([& params]
(let [cmd (new java.util.ArrayList)]
(doseq atom params
(let [#^String prms (. atom split " ")]
(doseq p prms
(. cmd add p))))
(let [proc (new java.lang.ProcessBuilder cmd)
isr (new java.io.InputStreamReader (..
proc start
getInputStream))
sb (new StringBuilder)]
(with-open br (new
java.io.BufferedReader isr)
(loop [c (. br (read))]
(if (neg? c)
(str sb)
(do
(. sb (append
(char c)))
(recur (. br
(read)))))))))))
