Sudo -S with Terminal - Did something get messed up?

Question

Hey everyone,
I just had a quick question...Today I got my 2011 Macbook Pro from repair. Everything was replaced, so everything on my computer, including applications, was lost. I've been reinstalling them, no worries. I let someone with the proper software install Adobe Creative Suite, but I found out he was using a pirated version he had on an external, and I removed it - the company I work for would obviously not support it. However, after doing a bit of searching, I want to make sure nothing on my computer got screwed up, because when I found out it was pirated and I searched for it, there were some security concerns, specifically with the sudo -s command in terminal.
This is what was done (I think, this was in a "install.txt" file):
Run Osx/disable_activation_osx as root
  if you dont know how to do that, open a terminal window
  then issue sudo -s, a root shell will open
  then simply do "sh disable_activation_osx" w/o the ""
  or ./disable_activation_osx( make it executable chmod 755 disable_activation_osx
  you do that from the folder where disable_activation_osx is. (just copy it anywhere on your hdd)
  Or do it manually
  Add the text below to the bottom of your hosts file. To get to hosts file, type "sudo nano /private/etc/hosts"
# Adobe Blocker
127.0.0.1 lmlicenses.wip4.adobe.com
127.0.0.1 lm.licenses.adobe.com
When I checked the contents of the disable_activation_osx file, I found this:
echo "Do you wish to update your host file ?"
select yn in "Yes" "No"; do
    case $yn in
        Yes ) echo "127.0.0.1     activate.adobe.com" >> /etc/hosts;
          echo "127.0.0.1     practivate.adobe.com" >> /etc/hosts;
              echo "127.0.0.1     lm.licenses.adobe.com" >> /etc/hosts;
              echo "127.0.0.1     lmlicenses.wip4.adobe.com" >> /etc/hosts;
               break;;
        No ) break;;
    esac
done
Is this something I should be concerned about? And if so, should I just basically start with a completely clean version of OSX? Or is this something that is harmless? I wasn't sure because the script files don't seem to have anything but IP Addresses and URLs. But as I said, some websites were saying sudo -s can mess up your whole computer, and I don't want that!
Any help is appreciated!

Answer 1

What is there to be concerned about? The shell file is simply doing what you were instructed to do yourself manually.
By itself sudo -s doesn't screw up anything. It's what you enter next. Just be careful to either type or paste the instructions you were given. Or take it all to your IT people and ask them to fix it all for you.
