为了更好地说明，让我们列举 stdin 的每一行

$ dmesg | count | nth_rs 0 1 2 3
     0  [    4.095065] xhci-hcd xhci-hcd.3.auto: xHCI Host Controller
     1  [    4.100328] xhci-hcd xhci-hcd.3.auto: new USB bus registered, assigned bus number 4
     2  [    4.107985] xhci-hcd xhci-hcd.3.auto: Host supports USB 3.0  SuperSpeed
     3  [    4.109677] mmc_host mmc0: Bus speed (slot 0) = 50000000Hz (slot req 52000000Hz, actual 50000000HZ div = 0)
