in reply to get stdout stderr

I used to use IPC::Open3 for this type of thing. Now I use AnyEvent::Util::run_cmd:

use AnyEvent; use AnyEvent::Util; use File::Spec; my ($stdout, $stderr) = ('', ''); # I think these need to be empty str +ings, not undefs my $pid; my $cv = AnyEvent::Util::run_cmd [ qw(xcopy /Y /S /E /I /F /R /K), $so +urce, $dest ], '<' => File::Spec->devnull(), '>' => \$stdout, '2>' => \$stderr, '$$' => \$pid, # this line is optional, you may not need it. ; my $rc = $cv->recv();
(You can even run more than one of these at a time if you want, with a little extra code.)

[davido]: when i do get to that point I think I'll do it in a vm snapshot just in case. :)
[oiskuu]: tye, you were right: loginuid/sessionid are part of task struct if compiled with AUDITSYSCALL. I have some doubts if you should actually depend on that feature.
[Corion]: oiskuu: Depends on what you want to do with that information
[tye]: I'm not depending on that feature. But I could in this environment. I'm using getlogin(). shrug
[Corion]: For benign logging (which user started this DB instance), it's OK
[tye]: We use auditd for security monitoring. So we can rely on auditing being enabled. I'm not sure who would want to not be able to audit. Maybe some VM inside another system with audit?
[SuicideJunkie]: spies would want a system to not be able to audit.
