You cannot access all browser cookies. Only cookies set for the current domain and not marked 'http-only' (or 'secure' if you are on a non-SSL page).
In javascript use document.cookies
Update
The browser has built in functionality, as a security feature, to prevent you from reading cross domain cookies. As long as the javascript runs in the browser, there is no method to access those cookies, let alone execute a shell command. Google for: same origin policy.
What you basically are looking for has so many security/privacy implications, I don't even know where to start explaining the dangers.

I tried document.cookies as you told i got only current domain cookies but i need browser stored cookies. Is there any way to execute shell script or unix commands by javascript??

ok, if i use shell script i can't able to access the local machine cookie file. Am doing this to bypass the sites which asks subscription in php curl() function, do you have any better method to store all cookies of specific domain.

And even it is helpful if you can tell how to access the sqlite database from javascript
Imagine that was possible. You browse to an arbitrary site that loads third-party ads, a rogue ad reads all your browser cookies and, voilá!, some guy from the Russian Mafia has the "Remember me" cookies and session IDs for all your sites. He can read your e-mail, see your pics on Facebook and retrieve money from your PayPal account.

That i agree but is there any other way to access all cookies of a specific site using javascript??
function getCookie(name) {
// Split cookie string and get all individual name=value pairs in an array
var cookieArr = document.cookie.split(";");
// Loop through the array elements
for (var i = 0; i < cookieArr.length; i++) {
var cookiePair = cookieArr[i].split("=");
/* Removing whitespace at the beginning of the cookie name
and compare it with the given string */
if (name == cookiePair[0].trim()) {
// Decode the cookie value and return
return decodeURIComponent(cookiePair[1]);
}
}
// Return null if not found
return null;
}

function listCookies() {
var theCookies = document.cookie.split(';');
var aString = '';
for (var i = 1 ; i <= theCookies.length; i++) {
aString += i + ' ' + theCookies[i-1] + "\n";
}
return aString;
}
