Wizards (if there's any around this week),
I've got a regexp I'm using to replace one SID in an HKEY_USERS registry key with another, but I'm beginning to suspect there's something wrong with it. It does work, but in fiddling with it, I discovered that it still works when it shouldn't (I think). For example (output from a test script),
Old sid:
"Users/S-1-5-21-1294888362-425938668-1648912389-1005/Software/Microsoft/Internet Explorer/Main//AutoSearch"
Now change the sid:
"Users/S-1-5-21-135449575-3924064129-568730901-1013/Software/Microsoft/Internet Explorer/Main//AutoSearch"
Well, that's the change I needed, but... Here's the original regexp:
$line =~ s{[S\-0-9]{43,45}}{$new_sid};
And, when I changed it to this:
$line =~ s{S\-[0-9]{41,43}}{$new_sid};
it still worked, and I think that should've failed--because '-' doesn't match [0-9], right? That's when I began to suspect something was wrong. I don't know regexps well enough to be sure there's something wrong, or to know how to write the regexp I *really want.*
Please help...
Thanks,
Deane
