Re: stat & uid

If this is on a *nix system and you have read access to /etc/passwd (probably you're either root, or the system uses a shadow file) you could load it into an array and 'grep /^$uid/, @passwd_file_listing' then '$uuid = split /:/, @array_you_put_grep_output_into'...

tc1364, i'd advise you to use the function mentioned by davidrw. my solution will work, but it's ugly, slow and insecure in comparison. sorry about that...	[reply]

Let me tell you from experience - looking at /etc/passwd is badness. There are so many ways that someone may not be using /etc/password (NIS/NIS+, PAM, LDAP, ...) that ... well, just don't. By using the getpw* functions, you tap into the same C runtime library that the OS uses to validate logins. Which means you'll get the value as used on the system, and not some random value. It's just a good habit to get into. And, besides, File::stat and User::pwent are way too easy to use relative to grepping and spliting the /etc/passwd file. :-)	[reply]
