I found this on the internet to convert an IPv4 address (w.x.y.z) to
a decimal number.
w * 16,777,216 + x * 65,536 + y * 256 + z = decimalNumber
I then found the subroutine, ip2dec in the script below.
The script works, that's not my problem. The problem is "How does it
work"?
The "split /\./"

Hello,
Everywhere I read about cgi setuid programs says that it is wrong and must
never be done,
but nobody says how to circumvent the need of it.
In my case, I need to read a password from a protected file (read only,
owned by root) to connect to a database.
How can I do this without running setui

use Cwd qw(getcwd);
my $cwd = getcwd();
print map { -e "$cwd/$_" ? "$cwd/$_\n" : "$_\n" } @ARGV;
Or use rel2abs in the core File::Spec module.

Yes, use Cwd::realpath() See `perldoc Cwd` for details.

Programming is as much about organization and communication
as it is about coding.
[updated for today's programming]
I have a path like
"/root/Tools/Log/../../Bin2/Patch/../Settings/ServerInfo/", and it's
absolute path should be "/root/Bin2/Settings/ServerInfo".
and I use these codes to get what I want.
my $my_str = "/root/Tools/Log/../../Bin2/Patch/../Settings/ServerInfo/";
Replace_it: $my_str =~ s#[^\./]+/\.\.
