Good morning all!
I want to know if Im interpreting this if statement below right.
if(((1) || (0)) && (1)){
do stuff;
}
This is saying: if true piped into false, then true, then do stuff. Right?
What does the && stand for?

ifconfig
IFCONFIG(8) System Manager's Manual IFCONFIG(8)NAME
ifconfig - configure a TCP/IP device
SYNOPSIS
ifconfig [-I ip-device] [-h ipaddr] [-n netmask] [-iv]
DESCRIPTION
Ifconfig initializes a TCP/IP device setting the IP address and/or netmask. It will report the address and netmask set. This command may
be used if the system has not been configured properly yet. It is only used at boot time to set a fixed address for a system without a
physical ethernet. Normally the inet task will find it out by itself from the RARP server.
OPTIONS -h The decimal TCP/IP address to set.
-n The netmask to set.
-i Don't set the IP address or netmask if already set. This way ifconfig cannot interfere if the numbers have been found out by RARP.
-v Report IP address and netmask. This is the default action if there are no other options.
SEE ALSO hostaddr(1), rarpd(8), set_net_default(8), boot(8).
