REGEX help required and some sed/awk help as well
Hi guys,

I am coding a bash script that makes use of php scripts to pull URL's from a website. These url links will have numbers in them like 0.2.3
I want to make a regex that will yield me such numbers if I use a command like preg_grep.

Question1: I need a regex that will tell my preg_grep to get any three digit number separated by two dots. Would d\.d\.d be an appropriate regex?

Question2: As well once I get the number I need to strip it of its dots. In bash would this tactic work for numbers:
Code:
$ foo=1.2.3
$ echo "${foo//./}"
testtesttest

Or should I use sed?


But in php could I use the following
PHP Code:
$var1 = "10.000";
$var1 = str_replace(".", "", $var1); 


Question#3 If I use the php code could the result $var1 be used in a comparison to see which number stored in $var2 is greater using a if comparison condition?
