Programming This forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

network script

I really enjoyed writing this script.I don't know about y'all but I have a lot of fun working with Sed, Awk, etc.

Manipulating strings of information with commands always turns out to be a fun puzzle to solve. There are a million ways to approach the problem and a ton of solutions but I like to find the most efficient and effective way possible!

I know there are a few guru's and scripters here in the forums and if you wanted to give it a try, I have a small challenge for you.

Take the output from an iw network scan and end up with the SSID(No label) and it's respective signal strength(Again no label).

Stipulations - You may only use 2 languages and one call to each language.

Code:
iw wlan0 scan | ...
Example output:

Code:
attwifi -44.00
TWCWiFi -73.00
CableWiFi -74.00
Example input:

Code:

                 * VO: CW 3-7, AIFSN 2, TXOP 1504 usec

My solution ->

Code:
iw wlp2s0 scan | awk '/SSID|signal/{print $2}' | sed -e 'N;s/\n/ /;s/\(\-[0-9.]*\)\(.*\)\([a-zA-Z0-9]*\)/\2 \1/';

I don't have a wireless card available, do you have an example input?

Mmh, 1 language and 1 call possible?

Code:
iw wlan0 scan | perl -ne '$s=$1 if /signal: (-?.*) dBm/;print "$1 $s\n" if /SSID: (.*)/;'

Very nice,. looking at your regex though, i see a couple of things I would change:

Quote:
sed -e 'N;s/\n/ /;s/\(\-[0-9.]*\)\(.*\)\([a-zA-Z0-9]*\)/\2 \1/';
  • escape the dot
  • use .* for 'a-zA-Z0-9'
Code:
sed -e 'N;s/\n/ /;s/\(\-[0-9\.]*\)\(.*\)\([.*]*\)/\2 \1/';

I didn't think it was necessary to escape the dot since the dot covers one letterz character or number and that character was literally a dot lol either way works. I did over look the [a-zA-Z0-9] regex though. Nice eye!

I thought what I posted was pretty straight forward and fairly easy! Instead I get no replies and the thread is left for dead.

I definitely feel the love here. <- lots of sarcasm

Meh, not many. From what I remember, this forum has some great scripters. I figured I would have gotten more replies than I did. Thanks everyone.

I am a little confused (could just be me).

I ran the original script posted:
Code:
awk '/SSID|signal/{print $2}' input_file | sed -e 'N;s/\n/ /;s/\(\-[0-9.]*\)\(.*\)\([a-zA-Z0-9]*\)/\2 \1/'
And my 'input_file' contains the data from OP. The output I received was:
Code:
 -48.00e1
 -38.00yAP
 -46.00i
 -61.00iFi
 -50.00
 -73.00ywifi
 -72.00iFi
 -76.00iFi
 -68.00p
 -88.00n-MiFi5510L-5699
 -84.00M
 -61.00ywifi
 -82.00i
 -73.00i
 -70.00i
 -75.00i
 -72.00ywifi
 -69.00ywifi
 -70.00iFi
So my query is, I thought the output was supposed to look like:
Code:
attwifi -44.00
TWCWiFi -73.00
CableWiFi -74.00
