Re: return value from system call, exit status, shift right 8, bitwise and, $?

system() is one of those weird commands that do different things depending on their arguments. It you use a single string argument, the return status is the status of the shell (or CMD.EXE on Windows). Most often, this is zero (success) even if the shell could not find a program to run.

I'm not seeing that:

use strict;
use warnings;
use 5.010;

my $status = system( "foobar arg1 arg2 arg3" );
say $status;

--output:--
Can't exec "foobar": No such file or directory at 2perl.pl line 5.

YMMV. And here I thought I had it figured out. :( I wonder what happens on Windows.	[reply]
