Why does this return fail?

/tmp of course exist, but mkdir -p shouldn't return an error when a directory exist.

So why does the following fail?

system("/usr/bin/mkdir -p /tmp 2> /dev/null") == 0 or print("Failed");        
if ($?) {print("Failed");}

system("/usr/bin/mkdir -p /tmp 2> /dev/null");
if ($?) {print("Failed");}

From Bash I get the expected 0

# mkdir -p /tmp
# echo $?
0

It's /bin/mkdir not /usr/bin/mkdir. I know this not only because you said /usr/bin/mkdir fails and not only because I looked on my (Mac OS X) system, but also because such low-level, fundamental programs are often in /bin because they are required to boot a system etc.

By the way, you should not use system(mkdir) to make directories from Perl. I'm sure there are plenty of ways to do it more "natively" and with better error checking.
