File Types & I/O Rediction

I/O
I/O

I was has having problem in recognizing file types in my studies, therefore to learn I searched and read few documents and found these types under Unix / Linux:-

  • (-) – ASCII/ordinary files
  • (d) – Directories
  • (c) – Character Special Files
  • (b) – Block Special Files
  • (p) – FIFO Files or Pipes

Further everything which carry down with Input Output Redirection over entire Unix / Linux is followed by

  • Standard Input – “0” – Keyboard
  • Standard Output – “1” – Terminal / Display
  • Standard Error – “2” – Terminal / Display

Note:- It will be pleasure if someone would like to contribute more to this post
