Quick scripting 10points

Stefan Saliba — Wed, 11 Sep 2002 12:45:18 GMT

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

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

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

will give you the IP adress only .

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}'

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