An '''i-node''' is a '''database''' containing information (e.g. ''file type'', ''owner'', ''permissions'', etc.) for all files that are created on the Unix/Linux filesystem.<br><br>The ''i-node number'' is like a '''finger-print''', and is considered to be '''unique''' for each file on the Unix / Linux file system.<br><br>Referring to the diagram on the far right, issuing the '''<span style="font-family:courier;font-weight:bold;">ls''' </span> command with the '''<span style="font-family:courier;font-weight:bold;">-i''' </span> option displays the i-node number for each file. You can see that <u>each</u> file (whether it is a directory or regular file) has its own unique<br>i-node number.
