I want to see how many interfaces(ethernet cards) are
working using single command?

Answer Posted / alf55

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
