  • character and block device
    • character or raw device
      • for serial data transfer
      • on 'ls -al' first letter is 'c'
    • block devices
      • moves blocks to buffer and writes after 'sync' executed by 'syncer' daemon
      • on 'ls -al' first letter is 'b'

to test yet

  • cut
  • tee - sends output of pipe to additional place (file as well as stout f.e.)
