alias to show my own configured ip

parses the output of ifconfig to show only the configured ip address (in this case from interface eth0).

the regexp is quick'n'dirty im sure it can be done in a better way.

--> this alias does not show your "internet ip" when you're in a nat-environment

and if we have two (or more) active network interfaces?

ifconfig $if | egrep -o "inet addr:[^ ]*"
Comment by bandie91 331 weeks and 4 days ago

Assuming that the default route is via the network interface of interest:

/sbin/ifconfig $(netstat -rn | grep "^0.0.0.0" | awk '{print $8}') | awk -F: '/inet addr/ {printf("%s\n",substr($2,1,index($2," "))) }'

Comment by mpb 331 weeks and 4 days ago

there must be a simpler way to do this...

Comment by elzapp 331 weeks and 4 days ago
ifconfig $(route|grep default|awk '{ print $8 }')|grep 'inet addr:' | sed 's/.*addr\:\(.*\) Bcast\:.*/\1/'

to show ip of default route

Comment by professoralex 325 weeks ago

route -n | egrep "^0." | awk '{print "Gateway to the Word: "$2", via "$NF""}'
