The command:
ifconfig -a | (grep -E 'Link encap:|inet6 addr|inet addr:' |
grep -vE 'inet addr:|inet6 addr')
Would result with an output similar to:
eth0 Link encap:Ethernet HWaddr 00:90:f5:b7:6a:1c
lo Link encap:Local Loopback
sit0 Link encap:IPv6-in-IPv4
wlan0 Link encap:Ethernet HWaddr 00:24:d7:a7:16:c0
So the command:
ifconfig -a | (grep -E 'Link encap:|inet6 addr|inet addr:' |
grep -vE 'inet addr:|inet6 addr') | wc -l
would produce the count.
The problem here is that it would also count usages such as
"eth0:0".
To not count those devices use:
ifconfig -a | (grep -E 'Link encap:|inet6 addr|inet addr:' |
grep -vE 'inet addr:|inet6 addr:|:[0-9][0-9]*') |wc -l
