s0:0:wait:/sbin/rc0 >/dev/msglog 2<>/dev/msglog </dev/console

Can anyone tell me what is the meaning of this line.I understood upto the rc0 but from there to the end i didn't get it. Thanks.

It's shell I/O redirection.

X>Y redirects file descriptor X to file Y. In this case X is missing and defaults to standard output: this means that rc0's output is being written to /dev/msglog

X<>Y opens Y for read and write operations and assigns it to file descriptor X, in this case 2 (stderr).

<Y accepts input from a file (in this case /dev/console).

Bye,
Enrico.
