[SOLVED] Retrive (only) your IP Address from any page

EDIT: original title: Retrive your IP Adress Via 10.138 (http://10:138) with WGET | GREP

This is more related to Conky, which is, in a way, scripting-like (amateur scripting), so here goes...

Well, I'm using D-Link router and I just wish to get my IP Address from it instead of:

${execi 300 wget www.whatismyip.com/automation/n09230945.asp -O - -q}

or

${wget http://checkip.dyndns.org/ -q -O - | grep -Eo '\<[[:digit:]]{1,3}(\.[[:digit:]]{1,3}){3}\>'}

I want it from the following address:
http://10.138/wancfg.cmd?action=view

wget --no-cookies --no-cache http://10.138/wancfg.cmd?action=view --http-user=user --http-password=user -O - -q

or even

wget --no-cookies --no-cache http://user:user@10.138/wancfg.cmd?action=view -O - -q

but what to insert after wget | grep ??? (I tried -n 44 without success)

this is the code:

<link rel=stylesheet href='colors.css' type='text/css'>
<meta http-equiv='refresh' content='5'>

Well well well... what do you know:

wget --no-cookies --no-cache http://user:user@10.138/wancfg.cmd?action=view -O - -q

WORKS!!!

Can I be much more silly than I am now???

Please, can someone, briefly, explain this command:

grep -Eo '\<[[:digit:]]{1,3}(\.[[:digit:]]{1,3}){3}\>'

Anyhow, can someone, please, post here another way, and explain what each Letter/Command does what

I'm going from memory here, so I might get one or two things wrong.

\< and \> are word boundaries -- they will pick up e.g. 127.0.0.1 if it is by itself, but not 181203.1211111.23.43.4332242224.6729 which would otherwise match. "word" is any sequence of characters a-z, A-Z, 0-9, and underscore IIRC.
[[:digit:]] is a character class that just says to match any digit -- characters 0-9.
{1,3} is a quantifier that says "match the last thing at least once, but try to match it up to three times." Similarly, {3} is a quantifier that says "match the last thing exactly three times".
The parentheses are for grouping; the {3} quantifier refers to the entire subpattern in parentheses.
A dot . usually matches any character except newline. The backslash makes it a literal . so it only matches, well, dots.

So this pattern says:
Match a word boundary, followed by one to three digits, followed by (a dot, followed by one to three digits) three times, followed by a word boundary.

Make sense?
