your search is matching "(wildcard) + x" which led me to believe that your reference to an OS of $x was the same basic format and the only ones I can think of that end in x are the *nix family: Linux, Unix, Xenix, etc.

dude just give up the answer, all your going to get from now on is blind guessing on some very obscure piece of trivia
Sine no one really got it, and I'm leaving soon:
$ is an anchor in regular expressions. If you're using some application that uses regular expressions, you can search for 'stuff' to look for the word stuff, or '^stuff' to look for lines that begin with the word stuff, or 'stuff$' to look for lines that end with the word stuff. Similarly, you can search for lines begiining with 'x' by using '^x' and lines ending with 'x' by using 'x$'. Hence, x$ matches anything that ends with x, which is basically the same set of unixes that *nix refers to: unix, linux, xenix, irix, etc.

Apparently all those who tried guessing the right answer
Hey Notfred, thanks for the explanation
bah, i was just about to post the answer too, and i actually knew it
basically, *nix isnt a generic enough term since linux is not *nix, it is *nux, but since most unixes end with x, x$ matches them all. the regex wasnt apparent to me at first, i was thinking "x plus some text", where $ could just be whatever, a variable variable, whatever

No problem
Also, if oyu go back to the link I posted as a hint, and hit "advanced search" it has a mini-regex tutorial that explains most of it
Hmm, that is what I was looking for the other day. The ^ character always stays with me because I use "ls -la|grep ^d" all the time but I wanted to know what the special char to find characters at the end of lines.

It means Micro$oft. And you've been spending WAY too much time with perl if you're coming up with stuff like this at 6pm on a Friday night.

Many of the VB [that's Visual Basic - something that microsoft made - they also made windows, so I think this counts] functions that deal with strings come in two flavors - one that ends with a dollar sign ("$") and one that doesn't. An example is Left$ and Left. The function that ends with the dollar sign returns a variable of type String, whereas the other function (without the dollar sign) returns a variable of type Variant.Originally posted by: notfred

See? Just because $ means something to you doesn't mean it means the same thing to everyone else. So really your original question is somewhat meaningless.
