Is the better option on a Open SuSE Box
1ifconfig | egrep [0-9A-Za-z]{2}\(:[0-9A-Za-z]{2}\){5} | awk '{print $1 ":\t" $5}' -
Print the IP address and the Mac address in the same line Show Sample Output
1ifconfig | head -n 2 | tr -d '\n' | sed -n 's/.*\(00:[^ ]*\).*\(adr:[^ ]*\).*/mac:\1 - \2/p' -
not shown ifconfig error
1for i in `lanscan -i | awk '{print $1}'` ; do ifconfig $i ; done 2> /dev/null -
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 Show Sample Output
0alias showip="ifconfig eth0 | grep 'inet addr:' | sed 's/.*addr\:\(.*\) Bcast\:.*/\1/'" -
0ipconfig getpacket en0 | grep yi| sed s."yiaddr = "."en0: ". ipconfig getpacket en1 | grep yi| sed s."yiaddr = "."en1: ".

Simple MAC adrress, thanks to ifconfig.
0ifconfig | awk '/HW/ {print $5}' -
0ifconfig -a| awk 'BEGIN{FS="[ :]+"} /Bcast/{print $4}'

If you are interested in interfaces other than eth0 you will need to change eth0 to your interface name. You could use this mammoth to nab the ip4 addresses of all your interfaces perl -e '@_=`ifconfig -a`; sort(@_); foreach(@_) { /(inet addr\:)(\d+.\d+.\d+.\d+ )/; $_=$2; @uniq=grep($_ ne $prev && (($prev) = $_), @_);} print join "\n",@uniq,"\n"; ' it seems silly to have all this code when the following will work fine ifconfig -a | grep "inet " | awk -F":" ' { print $2 } ' | cut -d " " -f1 Show Sample Output
0perl -e '$_=`ifconfig eth0`;/\d+.\d+.\d+.\d+ /; print $&,"\n";' -
0netstat -in
-
0ifconfig eth0 | awk '/inet / {print $2}' | cut -d ':' -f2
-
0ifconfig eth0 | grep -o "inet [^ ]*" | cut -d: -f2

This also works on non-Linux machines. If you have GNU sed you can do it more elegantly:
ifconfig | sed -n 's/^\s*inet \(addr:\)\?\([^\s]*\) .*/\2/;T;/^127\./d;p'0ifconfig | sed -ne 's/^.*inet \(addr:\)*\([^ ]*\).*/\2/;te' -e 'd;:e' -e '/^127\./d;p' -
Why use grep and awk?
0ifconfig | awk '/HWaddr/ { print $1, $5 }' -
0ifconfig | grep "inet" | grep "broadcast" | awk '{print $2}'
-
more variety
0ifconfig | grep "inet" | tail -1 | awk '{print $2}' -
0ifconfig eth0 | grep HW | cut -d " " -f 11
-
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 :) Show Sample Output
0ifconfig | grep inet -
Thx Mass1 for the sharing
0ifconfig | egrep -A2 "eth|wlan" | tr -d "\n"| sed 's/\-\-/\n/g'|awk '{print "mac: "$5 " " $7}' | sed 's/addr:/addr: /g' -
Gives the DNS listed IP for the host you're on... or replace `hostname` with any other host Show Sample Output
0host `hostname` | rev | cut -d' ' f1 | rev -
0netstat -nr|egrep -v "Routing|Interface|lo0"|awk '{print $5}'|sort -u| while read l; do ifconfig $l ; echo " Station Addr: `lanscan -ia|grep "$l "|cut -d ' ' -f 1`" ; done
-
On wired connections set 'eth0' instead of 'wlan0'
-1sudo ifconfig wlan0 | grep inet | awk 'NR==1 {print $2}' | cut -c 6- -
get desired info from machine and pipe it txt file. Show Sample Output
-2echo "-------------" >> nicinfo.txt; echo "computer name x" >> nicinfo.txt; ifconfig | grep status >> nicinfo.txt; ifconfig | grep inet >> nicinfo.txt; ifconfig | grep ether >> nicinfo.txt; hostinfo | grep type >> nicinfo.txt; -
-2ifconfig | grep "inet addr" | cut -d: -f2 | cut -d' ' -f1
-
This is what we use. You can grep -v 127.0.0.1 if you wish.
-2ifconfig | grep -o "inet [^ ]*" | cut -d: -f2 -
-2ifconfig | awk -F"[: ]+" '/inet addr/ {print $4}'
