What Does Su -l Do...and Why Would You Have To Sudo It

Hi

I'm focusing on getting my head around interactive v non-interactive shells, both non-login and login. Basically what scripts are run and how local and global variables behave.

I'm pretty much there except for 'non-interactive login shells'. I understand that 'non-interactive' shells are started when a script is run. However, if I start my script with #!/bin/bash --login, then a 'non-interactive login' shell will be started.

In my mind I would have expected this to be the same as logging in from scratch, albeit without a user\password prompt. In this case I would have thought that any exported variables from the parent shell would be blown away. This doesn't appear to be the case. The 'non-interactive login' shell appears to inherit the environment of its parent 'interactive' shell.

Can anyone explain the purpose of a 'non-interactive login' shell and how they behave in this regard.

Hope this makes sense.

Cheers

Mike

Trying to eliminate login password requirement ubuntu 15.04.
instructions say

sudo visudo

I can make changes but have no idea how to save and exit!

CentOS Linux 7 (core)
Kernel 3.10.0-299.el17.x86_64 on an x86_64
local host login:kd
[kd@localhost ~]$

The above is what displays on a black screen.
The program was d/l to DVD and then installed on a usb stick and booted from there. No password.

This is the second installation. On the first, a pw was specified but at login, it would not accept input from the keyboard except the enter key which resulted in Incorrect Password.

Help would be much appreciated.

->Need to upload a file from Unix box(Putty) to a website.

->Tried Wget and curl to upload a file to that website, when ever i am trying to fire the command its redirecting to Login page.

->for this purpose i have used cookies option to pass the Login information next time, but its giving empty cookie file and returning entire HTML page.

->used various options like redirecting,load cookies, for wget and curl, but everything is going in vain.

->Normally browser login process for that website is :

1.Login page www.example1.com/login and provide username and password
2.redirected to another URL www.example2.asp and after clicking on a folder icon.
3.it is getting redirected to another URL www.example3.com/folders.do?id=12433434324

i have to upload the file in the third URL and to a particular folder in that page, folders are containing different ids.

Please share your knowledge on this and provide solution as best as you can ,thanks
