[SOLVED] output IP into a file

grail · 05-12-2010, 11:50 AM

Just to confirm ... you made this change - -F"[ ]*:[ ]*" - in code for ipbits?

Except for the fact that I don't have whatmask (so using output you gave me read from a file), this is what I am using and get:

192.168.0.0/18

Hi grail, 1st) like to thank you very much for your help. 2nd) yes i did made the change.
if it helps you can download the whatmask program here:

i will continue working on code you gave me since it is working for you. Maybe i am doing something wrong.

tried several times getting the same result...!!!

NetRock · 05-12-2010, 03:22 PM

still scratching my head!!! from my end i am getting :
192.168.23.65 /20 (with the last code) !!!
tried different ways but still NO GO!!!

NetRock · 05-12-2010, 04:28 PM

maybe the extra space 192.168.23.65 /20 coming from "awk" ??!!

grail · 05-12-2010, 06:53 PM

Yes the awk "was" outputting the space prior to /20, but the new code removes it.
Just thought I would confirm, again, that we are on the same page with the following line as i have tried it several times and it does work.
(I would also mention that copy & paste from the forum does sometimes not include all spaces!!)

Code:

ipbits=$(ifconfig eth0 | awk -F: 'NR==2{print | "whatmask "$NF}' | awk -F"[ ]*:[ ]*" '/CIDR/{print $2}')
#                ^    ^ ^   ^   ^            ^ ^         ^      ^ ^   ^    ^    ^   ^             ^

All ^ refer to spaces. i jknow some are obvious but thought I would list all to be clear

Thanks grail for your great reply. taking the time & pointing the spaces, I appreciate very much- SMART.
I will try in the lab & let you know in the morning. from what i see when i copy & paste the spaces between the [ ]do not carry over.
I will confirm it tomorrow. Once again, BIG thanks for the good job & helping me.

Hi grail,

it is working now. so it was the spaces between [ ]. Now i am working on the rest of the project to get it to the destination!!
Thank you for your help.

No Prob ... glad you are on your way

The content of A is:
hostname 192.168.23.65
hostname 10.18.13.253
hostname 10.18.16.253
hostname 177.23.56.58

run the following command:
cat A | awk -F " " '{print $2 > NR}'

If contains 4 lines, the command creates 4 files : 1 2 3 4
file named 1 contains the first filtered line.

I forsee a problem with this logic, have a look at new fileA submitted by OP with comments in it. NR then starts at 4 and 7 gets missed due to repeated IP.
