System2 - like system(), but with STDERR available as well
use System2;
$System2::debug++;
my ($out, $err) = system2(@args);
my ($exit_value, $signal_num, $dumped_core) = &System2::exit_status($?);
print "EXIT: exit_value $exit_value signal_num ".
"$signal_num dumped_core $dumped_core\n";
print "OUT:\n$out";
print "ERR:\n$err"
Execute a command, and returns output from STDOUT and STDERR. Much like system(). $? is set. (Much cheaper than using open3() to get the same info.)
If $debug is set, on-the fly diagnostics will be reported about how much data is being read.
Provides for convienence, a routine exit_status() to break out the exit value into:
- the exit value of the subprocess - which signal, if any, the process died from - reports whether there was a core dump.
All right from perlvar(1), so no surprises.
Although I've been using this module for literally years now personally, consider it lightly tested, until I get feedback from the public at large.
Have at it.
