#Linux follows the Unix Philosophy where almost all things are treated as a file. The file could be:
- a regular file that contain encoded characters
- a directory which contains names and i-node numbers of the other files
- a character or block special file that represent I/O devices
-
a FIFO file to indicate a named pipe file (with a prefix
p) -
a symbolic link that point to other file (with a prefix
l) - a socket file for network connections
