I'm using the URL Regex feature of Squid for allowing sites via a list of regex strings to match allowed domains. The regex was actually copied from our previous proxy solution and it seemed to "just work". But, we've recently discovered that some domains (likely due to virtual hosts or host header configuration depending on if it's Apache or IIS respectively) fail if they are used without the www prefix in the URL. Below is an example of what sometimes works:
Code:
http://.*\.microsoft\.com/.*
The '.*\.' before the 'microsoft\.com' portion SHOULD mean, any number of any characters (zero or more) followed by a '.' I see the error in terms of the '\'. portion of the regex and plan to fix that. However, I've been unable to find a way to match both 'www.microsoft.com' and 'microsoft.com'. Here's what I thought would work:
Code:
http://[!.*|.*\.]microsoft\.com/.*
I admit to being really bad with regex, so please don't be too hard on me please. I've just never been able to "get it" 100%. Needless to say, the above doesn't work for me at all. It matches neither 'microsoft.com' nor 'www.microsoft.com'. I've tried some limited testing with 'grep' to try and find an adequate solution. But, what is it that I'm really trying to match? At first, I assumed I wanted a whitespace character, but I'm not looking for ' microsoft.com'. Then I thought, a null? But that seems to be impossible to match since it's not really a match at all since there's no character there. I'm sure someone who is an expert at regex would look at this and provide something insanely simple. I really don't want to do this:
I want to use find to locate files with two different extensions, and run a grep on the results. The closest I have gotten is incredibly slow and ugly:
for i in `ls -laR|egrep -e '(.js|.css)'`; do find . -name $i -print|xargs grep -H searchBg; done;
This method makes my eyes bleed. Help! ;)

Hello,
I would assume the expression ^$ should match a null string. Yet when I run:
echo -n | sed 's/^$/nullstring/'
I get no output.
Can anyone tell me why? (6 Replies)
Let's say I'm trying to match potentially multiple sets of parentheses. Is there a way in a regular expression to force a match of closing parentheses specifically in the number of the opening parentheses?
For example, if the string is "((foo bar))", I want to be able to say "match any number of... (7 Replies)

Hi,
I'm trying to validate if a string matches a regular expression, but it is not working. Am I missing something? Do I need to scape any of the characters?

echo Valid value
