To see which character device lines are currently used for the system console

/dev/console, you may simply look into the file /proc/tty/consoles:



  > cat /proc/tty/consoles

  ttyS0                -W- (Ep)        4:64



The columns are:



  device               name of the device

  operations           R = can do read operations

                       W = can do write operations

                       * = it is standard input of the reading process

  major:minor          major and minor number of the device separated by a colon



If the reading process holds /dev/console open at the regular standard input

stream the active device will be marked by an asterisk:
