awk hack

[lawrenzo_1]

Hello all,

I have written a bit of a hack but am sure I can get the desired output within one statement:

# netstat -rn |awk '/default/ {IP = $2};END{print IP}'|awk -F"." '{print $1"."$2}'

172.20

what is the best syntax for running this with one awk?

thanks

Chris

Hi Chris:

# netstat -rn |awk '/default/ {split($2,a,".");print a[1]"."a[2]}'

Regards!

HI (again) Chris:

It's worth remembering that you can set your output record seperator to write the solution thusly, too:

# netstat -rn |awk 'BEGIN{OFS="."};/default/ {split($2,a,".");print a[1],a[2]}'

Regards!
