Answer 1

Following command doesn't work if your are under proxy.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Instead user following -

ruby -e "$(curl -x http://DOMAIN%5cUSER_NAME:PASSWORD@PROXY:PORT -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Note we have to use %5c instead of "\" Similarly if your password has any special character replace it with unicode e.g for @ use %40 Refer this Unicodes

Replace above command with your own params

DOMAIN - Your Domain

USER_NAME - Your User Name

PASSWORD - password

PROXY - 10.10.10.10

PORT - 8080

After I had tried everything described, I looked up into the folder permission of brew in /usr/local/etc/. Somehow the permission were changed and I was not able to open the folder. I changed the folder permissions(with chmod) with same permissions as the other folders and brew start working.

Open Terminal and put below command.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Uninstall:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Once install complete after entering brew commands:

Brew has now been rewritten in Bash!

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Here is a version that wraps the homebrew installer in a bash function that can be run from your deployment scripts:

install_homebrew_if_not_present() {
    echo "Checking for homebrew installation"
    which -s brew
    if [[ $? != 0 ]] ; then
        echo "Homebrew not found. Installing..."
        ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    else
        echo "Homebrew already installed! Updating..."
        brew update
    fi
}

And another function which will install a homebrew formula if it is not already installed:

brew_install () {       
    if brew ls --versions $1 > /dev/null; then
        echo "already installed: $1"
    else
        echo "Installing forumula: $1..."
        brew install $1
    fi
}

Once you have these functions defined you can use them as follows in your bash script:

install_homebrew_if_not_present
brew_install wget
brew_install openssl
...
