Hi guys,
I have a perl script using system function, owner is root, like,
print "Previous $?, $!" ;
system("mkdir --parents --mode=0755 /home/myhome/disp/archive") == 0
or die "Unable to create directory,$!, $?"
system function sometimes return non-zero value, $? is -1 $! is No child
process, but the directory is actually created and mode's changed, There are
enouhg file handlers and inodes. It also happens to touch, echo, open pipe.
$! error message No child process is already there before the system call as
i print $! before call system function.
Enviroment is:
Linux version 2.2.17 (gcc version 2.95.2 20000220 (Debian GNU/Linux))
perl 5.005_03
After reboot machine, it's disappeared on some machines, but not on some
machine.
Can you point me where i look at to find what causes the problem, or is
there other better way to trap system call error?
Thanks in advance.
