then i thought instead of putting sudo infront of every command just make the user type su and job done ie from there it will run all the commands as root
I thought I explained this in post #4 in this thread when I said:
Quote:
Nothing in your script after invoking su will be run with root privileges. The su utility, if given a proper password, will start a shell and nothing in the rest of your script will be run until that shell exits.
Once a user types the root password in response to invoking the command su (without operands), they can then type any commands into the shell that su starts for them and it will run those commands with all of the privileges of someone who logged in as root. When they exit that super-user shell, your script will then continue running with the same privileges as the user who invoked that utility had when they invoked your script. No commands in your script after the shell started by su exits will run with root privileges unless it was root who invoked your script to being with.

The here-document trick I also showed you in that post can be used to feed commands into that super-user shell. The text in that here-document is just read and executed by the shell that su starts; it is not that su is running commands in your script.

The logical easy way to do this (if a user who is going to run your script knows the root password and wants to run your script with root privileges) is for them to run su and then while in the shell that su starts have them run your script and do whatever else they need to do as root before exiting that super-user shell.

NAME
Plack::App::CGIBin - cgi-bin replacement for Plack servers SYNOPSIS
use Plack::App::CGIBin; use Plack::Builder; my $app = Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app; builder { mount "/cgi-bin" => $app; }; # Or from the command line plackup -MPlack::App::CGIBin -e 'Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app' DESCRIPTION
Plack::App::CGIBin allows you to load CGI scripts from a directory and convert them into a PSGI application. This would give you the extreme easiness when you have bunch of old CGI scripts that is loaded using cgi-bin of Apache web server. HOW IT WORKS
This application checks if a given file path is a perl script and if so, uses CGI::Compile to compile a CGI script into a sub (like ModPerl::Registry) and then run it as a persistent application using CGI::Emulate::PSGI. If the given file is not a perl script, it executes the script just like a normal CGI script with fork & exec. This is like a normal web server mode and no performance benefit is achieved. The default mechanism to determine if a given file is a Perl script is as follows: o Check if the filename ends with ".pl". If yes, it is a Perl script. o Open the file and see if the shebang (first line of the file) contains the word "perl" (like "#!/usr/bin/perl"). If yes, it is a Perl script. You can customize this behavior by passing "exec_cb" callback, which takes a file path to its first argument. For example, if your perl-based CGI script uses lots of global variables and such and are not ready to run on a persistent environment, you can do: my $app = Plack::App::CGIBin->new( root => "/path/to/cgi-bin", exec_cb => sub { 1 }, )->to_app; to always force the execute option for any files.
