Full Discussion: /dev/console file

If you had been on system A and used ssh/telnet/rlogin to go to system B and tried that command, you would have gotten the expected result.

Since you were on the console of the system, /dev/console was returned. It is, simply, the 'terminal' associated with the monitor attached directly to the server.

You can find more information by reading the man pages for the following commands and then trying those commands (you should always have an understanding of what a command will do before attempting to use it).

$ man file
$ man ls
$
$ ls -l /dev/console
$ file /dev/console
