I don't have an option to execute brew cask as sudo user

[xabim]

General troubleshooting steps

• I have retried my command with --force and the issue is still present.
• I have checked the instructions for reporting bugs (or making requests) before opening the issue.
• None of the templates was appropriate for my issue, or I’m not sure.
• I ran brew update-reset && brew update and retried my command.
• I ran brew doctor, fixed as many issues as possible and retried my command.
• I understand that if I ignore these instructions, my issue may be closed without review.

Description of issue

In order to execute silent and unattended scripts I don't have an option to pass the password question and my script gets paused waiting for the password.

I want to know if there is a possibility to run sudo brew cask with a option like --run-as-sudo and maybe a warning but let the script continue without asking the sudo password

If I remove the root check the sudo command works, maybe we can relax this option and develop the above flag.

Output of your command with --verbose --debug

sudo brew cask reinstall teamviewer --verbose --debug
Password:
Error: Running Homebrew as root is extremely dangerous and no longer supported.
As Homebrew does not drop privileges on installation you would be giving all
build scripts full access to your system.

man -P 'less -p SUDO_ASKPASS' brew-cask
man -P 'less -p --askpass' sudo

I don't see how that solution can give me the privilege to execute the script unattended

If I execute the command line and the installation of brew as root (with or without sudo) I can't make it work, I don't see the ability to launch it without typing the sudo password at any time.

I use an agent to execute those scripts, and can be done with or without privileges.

Ok thanks, the issue there is that you have to type the password (at least one time), and we are deploying through an MDM tool, that executes scripts in a unattended way, I mean, you don't have the opportunity to type anything, and the other option is to write the admin pass in the script, and I found a big security issue there.

I only see two options:

1. Create a user, give NOPASSWD rights with sudo and execute all the commands with that user (but I see a security issue there)
2. Fork the repo and try to delete all the sudo checks, and install brew system-wide

Thanks for your time

Your particular case is pretty specific, so we’re likely not going to support that more than we already do in the pointed feature.
