how can I read the last two lines from a big log file without load it into memory completely? I need read it every 10 secs(On a Win machine)...and I'm stuck trying to read the last lines.. package main import ( "fmt" "time" "os" ) const MYFILE = "logfile.log" func main() { c := time.Tick(10 * time.Second) for now := range c { readFile(MYFILE) } } func readFile(fname string){ file, err:=os.Open(fname) if err!=nil{ panic(err) } buf:=make([]byte, 32) c, err:=file.ReadAt(32, ????) fmt.Printf("%s\n", c) } The log file is something like: 07/25/2013 11:55:42.400, 0.559 07/25/2013 11:55:52.200, 0.477 07/25/2013 11:56:02.000, 0.463 07/25/2013 11:56:11.800, 0.454 07/25/2013 11:56:21.600, 0.424 07/25/2013 11:56:31.400, 0.382 07/25/2013 11:56:41.200, 0.353 07/25/2013 11:56:51.000, 0.384 07/25/2013 11:57:00.800, 0.393 07/25/2013 11:57:10.600, 0.456 Thanks!
