ifconfig | grep inet

Functions: grep ifconfig
Tags: Linux ifconfig

Returns the IP, broadcast, and subnet mask of your interfaces absent any other extraneous info.

I know it's a bit lame, but I've created an alias for this when I *quickly* want to know what a system's IP is. Small amounts of time add up :)

ip addr show dev eth0 | awk '/inet/ {sub(/\//, " "); print $2}'
2012-12-11 12:12:50
User: 603k
Functions: awk

No grep or sed overload, just pure awk.

A=$(ip addr show dev eth0); A=${A##*inet }; echo ${A%%/*}

User: charley
Functions: echo

bash only - no grep, sed, awk, whatever - zero overhead

alternatively using ifconfig instead of "ip addr ..."

A=$(ifconfig eth0); A=${A##*inet addr:}; echo ${A%% *}

ifconfig |grep broadcast | awk '{print $2}'

User: fotoflo
Functions: awk grep ifconfig

get the ip address on your LAN

Know a better way?

If you can do better, submit your command here.

What others think

This does not work on linux. Bcast would contain the broadcast address but not the IP address.

Misspoke, "Bcast" would return the full line, but the word "Broadcast" does not exist in standard ifconfig output.

Comment by Karunamon 272 weeks and 2 days ago

1. grep overload: awk '/broadcast/ {...}'

2. ifconfig is obsolete: use ip

Comment by ioggstream 272 weeks and 1 day ago

This would not work.

Use any of the following:

ifconfig | grep -i bcast | awk '{print $2}' | sed 's/addr://' ip addr | grep inet | grep scope | grep -v inet6| grep -v '' | awk '{print$2}'| sed 's/\/..$//' ip a | grep inet | grep scope | grep -v inet6| grep -v '' | awk '{print$2}'| sed 's/\/..$//'
