“rd” exits with errorlevel set to 0 on error when deletion fails, etc
Wow, this is the 2nd case I’ve seen where ERRORLEVEL is not set properly! See File redirection in Windows and %errorlevel%. The solution is the same as for detecting redirection failure. Use the || operator to take action upon failure. rd testdir || echo The command failed! The bizarre thing is, when you use the … Read more

How do you capture stderr, stdout, and the exit code all at once, in Perl?
(Update: I updated the API for IO::CaptureOutput to make this even easier.) There are several ways to do this. Here’s one option, using the IO::CaptureOutput module: use IO::CaptureOutput qw/capture_exec/; my ($stdout, $stderr, $success, $exit_code) = capture_exec( @cmd ); This is the capture_exec() function, but IO::CaptureOutput also has a more general capture() function that can be … Read more
