In bash following processes each line as it is appended to a file:
tail -F tmp.log | while read LOGLINE; do echo `date` ":" $LOGLINE; done
In closh that could be:
tail -F tmp.log |> #(doseq [line %] (println (sh-str date) ":" line))
Make sure it can process potentially unlimited file. Make sure the pipe operator |> uses lazy-seqs.
|>
Make sure that piping large streams, e.g. /dev/zero will not run out of memory.
/dev/zero
