Quick scripting 10points

A quick one

I need to do "ifconfig lan0 | grep inet" and from the line I get I just get the IP address. i.e. pipe the output to something and get only the ip adress ??

ANY CLUES

[Pete Randall · Accepted solution]

ifconfig lan0 |grep inet |awk '{ print $6 }'

Hi,

For the quick and dirty way to get the IP address from something like this:



Try this:


# ifconfig lan0
lan0: flags=843
inet 10.100.12.23 netmask ffffff00 broadcast 10.100.12.255

# ifconfig lan0 | tail -1 | awk '{print $2}'

10.100.12.23


It may not work in all cases, but it is one way to do it.

Hi

try this

ip1=`ifconfig lan0 | grep inet | awk '{print $2}'`

echo $ip1

will give the ip address stored in a variable

hth,

One perl solution:

ifconfig lan0 | perl -n -e 'if (/inet ([\d.]*) netmask/) {print $1;}'

Couldn't resist, because I saw so many replys that suggested a piped combo of grep and awk.
Why on earth waste two processes with IPC involved where just one would suffice?

e.g.

# ifconfig lan0 | awk '$1~/inet/{print $2}'

[Jeff Schussele]

Very good point Ralph.

netstat -in | awk '{if ($1 == "lan0") print $4}'
