#!/usr/bin/env bash ## ## ## ## ## : ========================================== : Introduction : ========================================== # This script allows you to install the latest version of the # "firebase" command by running: # : curl -sL firebase.tools | bash # # If you do not want to use this script, you can manually # download the latest "firebase" binary. # : curl -Lo ./firebase_bin https://firebase.tools/bin/linux/latest # # Alternatively, you can download a specific version. # : curl -Lo ./firebase_bin https://firebase.tools/bin/linux/v7.2.2 # # Note: On Mac, replace "linux" with "macos" in the URL. # # For full details about installation options for the Firebase CLI # please see our documentation. # https://firebase.google.com/docs/cli/ # # Please report bugs / issues with this script on Github. # https://github.com/firebase/firebase-tools # : ========================================== : Advanced Usage : ========================================== # The behavior of this script can be modified at runtime by passing environmental # variables to the `bash` process. # # For example, passing an argument called arg1 set to true and one called arg2 set # to false would look like this. # : curl -sL firebase.tools | arg1=true arg2=false bash # # These arguments are optional, but be aware that explicitly setting them will help # ensure consistent behavior if / when defaults are changed. # : ----------------------------------------- : Upgrading - default: false : ----------------------------------------- # By default, this script will not replace an existing "firebase" install. # If you'd like to upgrade an existing install, set the "upgrade" variable to true. # : curl -sL firebase.tools | upgrade=true bash # # This operation could (potentially) break an existing install, so use it with caution. # : ----------------------------------------- : Analytics - default true : ----------------------------------------- # This script reports anonymous success / failure analytics. # You can disable this reporting by setting the "analytics" variable to false. # : curl -sL firebase.tools | analytics=false bash # # By default we report all data anonymously and do not collect any information # except platform type (Darwin, Win, etc) in the case of an unsupported platform # error. # : ========================================== : Source Code : ========================================== # This script contains a large amount of comments so you can understand # how it interacts with your system. If you're not interested in the # technical details, you can just run the command above. # We begin by generating a unique ID for tracking the anonymous session.
