Title:
  uniq is not checking and handling all file types

Status in coreutils package in Ubuntu:
  New

Bug description:
  Hi,

  The utility uniq allows all types of files as input. Allowing block
  devices or character devices as input can lead to unwanted behavior
  such as the utility executes indefinitely when device '/dev/urandom'
  is passed as an input. Please refer this for more information
  regarding this issue
  (https://github.com/pkmoore/rrapper/blob/master/anomalies/weird_filetypes.md).

  I've included a patch which checks and handles character devices and
  block devices when passed as input. Please get back to me for more
  information.

  Regards,
  Anoop Nadig
